Tour Aotearoa Sports Illustrated Bikini edition

Building a bike for the Tour Aotearoa  is not that easy. With the TA just around the corner ( feb 21 for wave 1) we have finally got to the pointy end of things. I am going to take a look at a few of the local riders bikes, my own, Bills, Matt G and Matt D's. Bill has been tweaking his gear with the kind of diligence that would get him a job at NASA if he wasn't slumming it as a lawyer. As older gentlemen we both appreciate the comforts that modern bicycle design can bring, but my build tends a bit on the zombie apocalypse side where as Bills is a bit more of a armchair ride. Ive always been impressed with the attention to detail in Bills bikes so it was a good chance to ask him some questions about it. The Matt(s) bikes are a bit more simpler in their approach, but are still completely different in many other ways.

We will start with mine. Its taken me 2 years of testing potential rigs for the inaugural 3000km Tour Aotearoa. I had plenty of bikes to choose from, a light Carbon 29er frame, a supple steel CX frame, a 29er alloy fully, a steel rigid and a 26er alloy fully. I narrowed it down, and went through countless iterations between my Karate Monkey and the Giant XTC. Racks, bags, flat bars, aero bars, drop bars, cranks, derailleurs. Bottle mounts. I tried several of the iterations more than once.


I even wrote a blog post on the pros and cons of racks vs seat-bags.

There are many reasons for my final pick, and I have tried to list most of my gear choices and their rationale below. The weight of the carbon Giant was tempting but the way you can just duct-tape or radiator hose-clip something onto a tubular steel frame just appeals to me. There is a 2 pound weight penalty but I don't feel that is much in the big picture, especially were peace of mind is concerned.
Same bags, different bikes...

 Frame An early steel Surly Karate Monkey, 4130 steel, horizontal drop-outs incase of derailleur failure so I can SS. This happened to me in my last Kiwi brevet, and the drop-outs saved my bacon. You could also argue that if I had a replaceable drop-out, and I replaced it I would have been better off, but these modern derailleurs are so flimsy I suspect it would have died as well.

Fork
Carbon. Nothing flash.

 Derailleur's
Rear-9 speed old school Deore XT derailleur. Strong pivots. Cable adjuster at the back so its tunable without inline cable adjusters when used with drop-bars. I ranted about it here once....
Front-3 speed old school STX narrow profile. Simple design. More clearance for my wheel than the modern designs, allows me to run the Karate Monkey with the short wheel base it came with. Some modern front derailleurs are really long.

Saddle
A circumcised Brooks B-17. I love this saddle, but that's easy to say when it hasn't been sat on for 3x18 hour days in a row so far. With the crappy weather expected I will need a cover.I was really happy with my Brooks Swift, until I tried the B-17. I think the width is what makes is so comfy.

Bars
Woodchippers and Profile aeros for maximum comfort, positions and aeroness. I had a spell without the Woodchippers, but I was so glad to return to them. Each of the many positions allows a completely different weight distribution for your arms and butt. The Woodchippers give a much more aero frontage than flat bars too. Aero makes a difference, even at slow speeds. I have to claw back some watts lost via my dynamo hub too I guess.

Shifters
Durace 10 speed on right. A gift from a friend. They work well. Not as bullet proof as bar-end shifters, but if they broke, I would adjust the cable to mid cluster and still run the three front rings and still have a massive range.
Bar-end shifter on left. Its not easy to get 3x shifting on drop bars with "brifters" and MTB cranks hence the bar-end shifters. Pauls make a  trigger mount that would work but I am happy with the simple 3 speed in friction  mode for simple trimming

My Tune Bigfoot in early 2x configuration
Brakes
cable BB7s because they are rock solid and work. No surprises with cables

Bags
Stealth Seat, Top-tube and Frame bags. Home-made front harness. Supporting local grown industry! The Stealth stuff has been totally bomproof in daily commuter use as well as weekend rides.

Pedals
XT. More reliable than XTR and not keen to go the Crank Bros route again!

Cranks
Tune Big Foot : 22/34/44 A gear for every occasion. I love this crank. I've had it for years. It has a swapable spider, but I prefer the compact to the ATB style of  BCD.

White Industries. Square taper FTW !
BB.
White Industries cromo BB, square taper. If my crank falls off, I can probably find a compatible one on the side of the road somewhere. Most of my bikes are square taper. The Giant has a press-fit BB which was another point in the Karate Monkeys favour.

Cluster
11-36

Lighting
SP dynamo hub with Exposure Revolution light. Will use for main lighting and USB charging of Etrex and phone where needed, also the 18650 rechargable lap-top batteries for my cache and torch. I may take a 2xAA torch as back-up. I wrote a piece about charging these batteries using the dynamo hub here.

Cages
3x plastic Topeak. Cheap off T7. Applied with insulation tape. Seems rock solid so far.

Rims
DT Swiss front. Stans rear. I have been told they make Stans rims oversize to fit non-tubeless tires better. They are not compatible with many of my first choices in tires. On the other hand, a wire-bead WTB Nano beaded up perfectly on them, apparently a Nano TCS wont fit.

Tires
WTB Nano TCS front, WTB Nano wire-bead COMP rear. I am not really a fan of tubeless in general. Hoping to save a bit of rolling resistance, I don't have great expectations for their self-sealing abilities given past experiences, especially with sidewall punctures. The Nano is a strange tire, and seems quite capable when you actually put your preconceptions aside. I cant see it as being confidence inspiring on wet roots though : )

Trialing Trevs bottle mounts.

Almost sorted...

I promise, no more tinkering!


------------------------------------------------------------------------------------------------------------------------------


And now for Bills bike, a beautifully set up Salsa Spearfish. Armchair comfort with a sensible gear range for oldies like ourselves.

Salsa Spearfish, why yes, his chain is blue!

Bills rear seat box.
Bill is the type of guy who spends a lot of time thinking about his kit and how it can best deliver the goods for him in the outdoors. If there is not an option good enough he will build his own.

Q. Is there an overall theme for the way this machine has developed Bill or is it just one iteration of many?

When I bought the Salsa Spearfish in 2014, it came with a Revelate frame bag which would be difficult to better, so I turned my attention to finding a way of making seat bags and a bar bag that better suited my needs. I didn't want to just buy the off the shelf versions even though there were, by then, several well thought out and professionally made options.The inspiration for the top tube bag box came from you, Jeff, when I saw a picture of your bike with a spare bottle mounted on the top tube. It seemed to me that, if you were going to use all of the top tube, then you would be better off with one box going the full length of it rather than setting three different items to it.

How long have you been working with carbon fibre for, and how did you get into it? 

I have been playing with carbon fibre for many years. That probably started before it was possible to buy decent lights for bikes and I wanted something better than the plastic drainage tube holders for Halogen bulbs that we were all experimenting with at that time. As a teenager, I was involved and sailing dinghies which meant that I learnt how to use fibreglass at an early age. Carbon fibre is just fibreglass with a more modern and cool looking fibre.

How many carbon items on the bike have you built? The seat box, top-tube and front roll?

I spend my day providing clients with advice and documentation. At the end of each day, I have a little physical evidence other than a mound of paper to show for that. I love making things in my spare time so that I have the satisfaction of seeing something physical for my efforts

I understand you worked with Michael at Stealth Bike Bags for your top-tube bag?

Yes, Michael at Stealth Bike Bags made the cover for the top box and was great to work with once he understood what I was after. It's great to see someone of his age being able to combine talent and passion into a viable business.

The mono stay aero bar, where did that originate from, I remember Trevor Woodward had one in stainless steel in one of he early Kiwi Brevets?

The single aerobar was inspired by Trevor's 2010 Kiwi Brevet with a stainless steel version. I'll give him credit for that now since he has since stolen (and bettered) my idea for a dual mount for bottles on the downtube.

A aero bar that rivals the Black Adders codpiece!
 There are plenty fullies out there at the moment, was there a particular reason that you went for the Salsa Spearfish?

After the Scalpel, I bought a Salsa Dos-Niner and loved it. Getting older, I looked for a bit more comfort and found that and performance in the Spearfish. An added attraction was that no-one else I knew had one.

Do you think that some riders in NZ tend to copy the trends of Tour Divide riders with rigid rigs regardless of the local terrain?

When the sewing machine chokes, get out the awl.
Yes, but I don't see anything wrong with that either. We need to start somewhere, take other's ideas and adapt them to suit our own needs. It's part of the development process.

I see you have the Jones Bars, do they give you enough positions for your hands or are you on the aeros most of the time anyway ?

The Jones bar provides lots of options for hand positions, especially with the bar bag mounted well below that by the carbon tube spaces. However, I find myself riding mostly on the Aero bars so a lot of the Jones bars' benefits are not utilised by me.

What does your light kit consist of, K-lite with a Lime-fuel for cache?

The dyno light set up was provided by Kerry Staite of K-lite. I have added a Lime Fuel Blast as a cache battery after trialling several other options. I'll place my faith and Kerry's advice in this regard as the remainder of the setup has proved very dependable.

Plenty of room here in Bills carbon fibre sandwich top box with fabric zip top.
Do you think the added complexity of a dynamo system is worth it in the NZ style of Bikepacking where you have a compulsory 6 hour stand down each day, stopping potential all-nighters?

I don't need the organisers of the TA to impose a six hour compulsory stand down each day. I intend to impose that (or more) on myself. Having said that, I would still back the dynamo system for those intending to ride 18 hours as it is important to minimise the time spent looking for places where you might charge the various devices on which we have become so dependable. All of my electrical items can now be charged via USB - headlamp, 2 rear lights, my iPhone, my iPod and my Garmin GPS.

If time and money were no object is there anything you would change on this set-up?

If money was no object, I wouldn't be wasting it on new bike parts. I would be working less, spending more time with my family and riding my bike. More time riding would result in a much better performance than any changes I might make by throwing more money on my bike. That doesn't stop me dreaming about other bikes, though. My ideal setup would be a Black Sheep custom frame with a Lefty front fork, Project 321 adapter and hubs, carbon wheels built by Oli of Roadworks, a Gates carbon belt drive and Rohloff gearing - with homemade bits made from carbon fibre by yours truly.

 Your bike seems very aerodynamic, is this something that was done on purpose or did it just evolve that way ?

Aero?  "I'm a Wellingtonian! Wind has a big influence on our days here. The urge to be as aerodynamic as possible goes back to the time spent messing around with triathlons. We did our wind training outside, not on rollers in front of the TV. I was a useless runner, so needed to gain as much of an advantage as possible on the swim and bike legs. There'll be plenty of wind on the TA to make it well worth being as aerodynamic as you can be. But, it's also essential that you be comfortable in the aero position. I do wonder about those who are trying to fit aero bars to their TA bikes a week or so out from the event. Not ideal."

---------------------------------------------------------------------------------------------------------

The next bike is Matt' Gs sadly recently discontinued Singular Gryphon. A bike he got specifically for the first  Kiwi Brevet in 2010. It has been added to over time with fruitier bits including a new Igleheart fork which was a replacement for the original one that met with a stubborn bollard one day.

Trialling the Bruce Gordon Rock n Roads, grippy but a bit slow on the road


What Matt G thinks.

Unlike Jeff, I have not put two years thought into my set up, and it likely shows. I built up a Singular Gryphon a little over six years ago for the first Kiwi Brevet and it completely changed – and made – my love for off road riding. I was disappointed to learn recently that Singular won't be making the Gryphon any more; I have had my heart set on a Ti Gryph since I first saw one.

Since then I have had little desire to move away from it, and I did not consider anything else for the Tour Aotearoa. I have become a massive fan of dirt drops. I put quite a bit of thought into the set up for that first Kiwi Brevet, but since then I have mostly only made changes when replacing bits whose lives had come to an end. Occasionally I can be rather overly particular when those changes are made, and I've got to thank Mike Anderson who has put up with endless faffing from me when helping me get the bike together and keep it running (unfortunately, I still maintain my triathlon influenced mechanicing skill)

Three of the main decisions I needed to make were tires, bag system and tent vs bivy: 

Tires: I have spent quite a bit of time with both fat and skinny tires on the Gryphon. For the Tour I couldn't get my head around the need for fat tires given the amount of road and gravel time and the competence and comfort I have found many skinny tires have in technical riding. Quite possibly I will change my mind in a few weeks time! I had been using Bruce Gordon Rock n Roads on my SSCX for quite some time, including a mountainous tour in Japan, and I am pretty enamoured with them. I feel like I am really giving up very little with them, even on moderately technical single track, So I initially planned on using them. After quite a few kms and wearing one down to the threads, I was pretty certain that they “felt” slower on the roads than I wanted. At that point I swapped to WTB Nano TCS 40s and have not looked back. I am running them tubeless and while I definitely do not feel as confident on them as the Rock n Roads, I am comfortable enough and they feel great on the roads. Having said that, I am infinitely more confident on them than on a previous pair of Stan's Ravens! They do feel a little floaty at times in loose gravel, but all-in-all I am pretty stoked with these tires.

Bag-system: In the past I have run Freeload racks or Freeloads and an Ortleib handlebar bag. My set up has always worked well. This time I was determined to use panniers, dammit. I struggle with many of the reasons and logic I see for the superiority of bags over panniers for most bikepacking. I will skip that fight for now, because, here I am, with no panniers, and with no racks.

I pretty quickly decided I wanted a holster style seat bag because I did not really fancy the idea of fighting with loading a standard bag and I also really liked the idea of a dry bag. I went for a Revelate Terrapin, partially influenced by the long lead-in-time required for a Porcelain Rocket (and my late planning). I have been very happy with the Terrapin, until I broke a buckle today. Operator error? Probably, but I am suspecting my dexterity and mental acuity will not be impressive after I get a couple of thousand kms in me. It's all fixed and sorted now. I hope. A key goal was to try and reduce the load I have carried in the past (maybe I have succeeded) and I also hate the look of a framebag. Yes, I know. Priorities. I also wanted to carry water bottles in standard places, so I had a custom half frame bag built up by Stealth Bike Bags. It's been exactly what I needed.

I need to carry a little more up front (where else will my Aeropress fit?), so I went for a Fairweather handle bar bag, which has a drybag which opens on both ends, plus another moderately sized pocket and a map-pocket. It has performed flawlessly. I can get my tent and sleeping quilt in it and have room for a bottle and plenty of food. I strap the tent poles to the outside of it.

Tent vs. Bivy: There was no real debate here. With two to three weeks (four!?) in NZ, it's going to get wet and grotty. I want to sleep out as much as possible so I ruled out a bivy. I have used them in the past and they have been sufficient, but I was looking for more. For reasons I cannot quite recall I decided on a Tarptent Protrail. The size and generally performance is certainly very good. However, after a night in 150kph gusts with either poles getting knocked down or pegs rocketing across the tussock, I decided I need a change – strong wind is a regular occurrence in this fabulous country. I am sure someone more clever and determined than me could make it work (that's why I sold it to Jeff), but I just did not want to deal with the uncertainty from it. After doing a bit more research I have switched to a MSR Hubba NX 1-person. I will never look back.

Everyone around me was going for dynamos. I thought it was an interesting idea, but I was not quite ready to commit to one. After seeing them in use for a while now, I think they are a very interesting idea, but I think I will wait until some of the supplementary electronics become a bit more robust; I suspect it should not take too long. I will probably pay for one in AA and AAAs during the Tour.

What Matt D thinks.

The other Matt, (Matt D) has gone all CX on us. The alloy Cannondale took over from his beloved Surly Straggler as his rig of choice in this years Hutt Cross Cyclo cross series. Normally I wouldn't suggest a CX bike for Bikepacking in NZ, but having ridden with Matt D on Barryn's "Brevets Little Brother" and seen his skills I suggest its not going to slow him down much at all.


 About the bike choice
Initially like others, I had trouble deciding on the bike. My choice was between a carbon 29r, steel cyclocross bike and an alloy cyclocross bike. In the end the alloy CX bike won over. The deciding factor probably came down to researching the TA route and the fact there will be a lot of time spent on tarseal and gravel. I also like the dropped bar setup as I think it'll be great to have plenty of hand positions. Of course there is going to be the odd section where the bike will not be ideal but I feel for the most part it will be.

I'm fairly new to this style of riding, so it's been great riding with seasoned brevet riders in the lead up to TA. They've been an invaluable source of knowledge and great to bounce ideas off and speak to about gear choices.

I have put a lot of thought into everything and there has been a real tendency to over-think every aspect of my setup. I'm ready now and looking forward to getting in to it.

Doozy on Brevets Little Brother.

Gear setup
CaadX 105 alloy frame with carbon fork 

11 speed
road setup running 11-40 on the rear and 34/46 on the front. A Wolftooth Roadlink mounted to the hanger has allowed me to run a decent sized cassette on the rear giving me a large gear ratio.

Bars
are Salsa Woodchippers and I find these really comfy. Have opted not to run an aero bar as I've never really been into them and I'm not a triathlete.

Bags
are all Stealth; Seat bag, top tube bag, harness, frame bag with loads of space. It's been great having a locally based manufacturer to deal with and have done many trips out to Eastborne over the last year or so. Water storage goes in a bladder in the frame bag and in a basic camelback.

Lighting/charging: I went with a SP dynamo hub with Exposure Revo light and Limefuel blast cache battery.

Charge spoon saddle is nothing fancy. I've done some pretty long rides on it and it's remains really comfortable.

Brakes are BB7s. When they're set up correctly you can't fault them.

Wheels Stans Arch on the rear and Crest on the front.

Tires are tubeless WTB Nano race 40c. I am a little worried about the rear wearing quickly so I have a spare in waiting Wellington at the half way point.



Ready to roll.


One of these Matts is not like the other.

Take the long way home

Last friday I came in to work early with the idea of sneaking out early and doing another evening ride. I reckon its a great opportunity to test gear in its intended environment. I had plenty to test. Once again I had oscillated from my Karate Monkey to the plastic fantastic Giant XTC. It has all the personality of a tupperware container but the frame weighs about as much as the rigid front fork on my Karate Monkey. At the last minute I "Pocketed" a few stories from the Inspiring riding site, onto my phone so I could have them "TTS" read to me by the robotic English woman, whose voice I had chosen, and I also downloaded a couple of podcasts from an MTBing site to keep me company.

I was going to do the "Big Coast" a loop from Lower Hutt and across the Rimutaka incline, down the side of Lake Wairarapa and back along the south coast.

Given that it was reportedly a southerly I was a bit peeved to be experiencing a bit of head wind as I headed north up the Hutt Valley, not a lot, but enough to make it less enjoyable. The first podcast I started listening to was about Bikepacking but after they mentioned people cranking out 400 mile days it kind of lost a bit of credibility with me. I hung a right early on and elected to take the hilly approach to the incline rather than the usual drawn out flat one. It had been ages since I'd gone that route. It was a welcome change. It was my first ride with my new Stealth frame bag, and I was also testing a couple of Klite
A piece of art I created called Nexus Marshmallow
Kerrys 3d printed anything cage mounts. A couple of things were immediately obvious. My actual bottle cage was crap, it was scrounged off a TT/road bike, and every time I pointed downhill in the rough, the bottle fell out. The other thing was, the Giants top tube was a lot higher than the Karate Monkey's so the GTB (groin to bottle) clearance was not ideal. The Klite anything mount also added a bit of height. The last time I had a bottle on my top-tube is was on a much smaller frame and was mounted directly with radiator hose-clamps.

Approaching Cross Creek
I was enjoying Andy Kerr's Inspiring Riding tale about custard squares as I was grovelling up those first climbs, but decided to save the rest of the stories for "optical" reading, as a fair bit gets lost in translation with Text To Speech.

I came across a woman on a touring bike part way through the Incline. Her bike was fully loaded and it had taken her all day to get from Wellington to part way up the Incline.

By now I had switched to AM radio for entertainment. 567. Yes RNZ. I banzaied my way through the Incline's tunnels with my dynamo lights blazing away. When I made it to Cross Creek I was surprised that it was 6:30 and I had been riding for 2 hours 40. I guess I had been stopping a lot to take photos.

Ruamahanga 50. 80km Time trial lives here.
It was a lovely day in the Wairarapa and I was down on the aeros all the way down the side of the lake, and past the turn-off to the Ruamahanga 50, the site of one of my most favoured events.

It was actually pretty cold, but more as a result of speed induced windchill into the southerly I think. I had already stopped to put on a high necked poly-prop at Cross Creek, and I still had rain pants. leggings and a rain jacket at the ready should it get nasty. In hindsight I should have thrown in my bivvy sack and sleeping bag as well, its not like they take up a lot of room, and I had plenty spare.

I stopped at the top of the hill before the descent down to the coast and texted my daughters to say I would be a bit longer than I had said.


I got to the coast and started noticing the rabbits everywhere. There is a real problem over there. Lots of young ones. A few people had already turned up to their holiday baches on the Coast and were settling in for the weekend. I'd been pedalling for around 4 hours 15 at this point.

I see the sea.
The sun started to go down which added to the ambiance of the ride. I bowled through the Corner Creek camp site. No one there. Its my favourite time of the day to be riding, dusk. The Revolution light/SP dynamo  was more than up to the task but I knew it would be useless soon enough when I hit the stretches of unrideable deep sand and scree. I flicked on my 10$ head torch and grunted my way through the gnarly scree. I knew there was a fast line through it somewhere, but I had no idea where, its hard enough to spot it in the daylight hours as it is. The track seemed to disappear a bit at times, maybe due to some heavy rains earlier in the week. Somehow I managed to find my way across the river/stream with minimal fuss, barely getting my shoes wet.

Even though the thick sand and lumpy scree is slow going,  within a couple of hours I was at the Orongorongo end of the trail. Part way along the coast I had got a few texts from the kids when I surprisingly ran into some cell coverage. I had set up my phone with the "Wheres my droid" app.
If anyone texts me a special predetermined word, the phone messages back to them with my lattitude and longitude in a clickable link which will open in Google maps or a web browser. It only works if you have your GPS on, which it is by default if you are using Strava, but you also need cell coverage.

So now I was at the Orongorongo farm, and out of cell coverage again. I decided against doing the proper Big Coast course, over the hill and around to Pencarrow, as it was already late, and so with a slight tailwind I got down on the aero-bars again and motored along, destination Wainuiomata. That stretch bores me to tears, but I had to keep alert, as on 4 separate occasions I was attacked by marsupial suicide attack team of possums who shot out from the side of the road and nearly took me down. Maybe my dynamo light was attracting them. They seem to be inherently more stupid than a rabbit as far as road sense goes and their bow-legged gait has got to be more useful for scaling and decimating native trees trees than negotiating 3/4 chip at speed.

I called in at the first gas station at Wainuiomata and squaffed a coke and a hot coffee. I felt like a strange alien impostor as I witnessed the banter between the locals and the staff. I most likely looked like an alien  with my thousand yard stare and flashing gizmos on my lid. "Take me to your barista!" I had probably already eaten about 5 muesli bars from the expired stash recently inherited from my work and less than 2 bottles of water and electrolyte drink at that point.


I got a text from Ash to say she had cooked me a nice tea for when I got home. With my caffeine levels topped up I scaled the Wainui Hill and opted for the trail down the other side rather than push my luck with local Friday night bogans on the road proper. I have to say everyone was on their best behaviour that night. The Coast road can be a scary place on the wrong day.

Petone foreshore with the lights of Wellington in the distance
At 11pm on RNZ they were playing an hour long doco on the Legendary Sun Ra who I had only vaguely heard of. It was a pretty interesting listen as I rode along by myself into a the Wellington CBD.

 An hour later at 12.00 on the dot I staggered down the stairs and knocked back the delightful meal I found waiting for me. Thanks Ash!  8 1/2 hours after I had left work I was home. 148kms under the belt and some lovely terrain covered and gear tested. My legs felt great on my final climb up the Brooklyn  Hill and I had no significant gear issues. My shorts were mint. No chafing anywhere. 

The plastic fantastic did the job. But do I want to ride it for up to twice that amount of kms a day in the upcoming TA ?  Maybe my next big coast will be on the Karate Monkey again....

Plastic fantastic vs steel is real....
How google earth sees it.

The poor mans Diablo

Exposure Diablo
The Exposure Diablo is a light that is very popular with Bikepackers because it can be charged via USB, via a dynamo, and it can also be used as a power-bank to top-up devices. (USB in and USB out).

I call my set-up the "Poor Mans Diablo".
The Rich Mans "Diablo" (RMD) costs about $300 NZ dollars. The Poor mans Diablo (PMD) does all the things the RMD does, at a fraction of the price. The RMD is one item. The PMD is effectively two.

The charger/powerbank are separate in the PMD. The PMD has the same sized battery inside in it as the RMD, a 3100 mah battery. Exposure make top-shelf gear for sure, and you could probably use a Diablo underwater if that's the way you Bike-pack ; )

I reckon if I wasn't using a dynamo system in the TA, this would be my sole lighting system. As is it, it is my back up. See the costings below for the PMD.


Torch + charger/power-bank + battery + cable + 3-pin USB plug. All that is missing is the helmet and bar mounts.

You could also use one of these. This one takes 2x 18650s.  Also
dirt cheap. I am not sure how they go charging two batteries of
uneven charge should one become more flat than another?
Final cost in NZ pesos:

Torch=13.27
Charger= 8.03
Cable=7.90
USB wall Adaptor=18.90
Battery=18.00
Bar-clamp=1.43
Helmet-clamp=5.85
Total=73.38 +


With a PMD you can carry multiple batteries. If you take another charging box, you could charge more than 1 battery at a time. You can get charging boxes that take 1, 2 or 3 18650 batteries. The reason I use the single one is that it does "pass-through" for use as a cache battery with my dynamo set-up. The double one above is not pass-through but both charges and can be charged.

Handlebar mount.
The quality of your PMD's torch beam will likely determined by how much you pay for it.

My 10$ ones wont likely be as good as a "name " branded one, like this Klarus XT2C that Nathan Mawkes uses in his set-up.

A higher quality torch may have a more even spread. This is where spending more could pay off. I am very happy with my torch for the money but would expect a more even beam from something like the Klarus.




I get 14, 7 and 3.5 hours out of one of these 3100mah batteries on high, medium and low settings. There is also strobe and SOS !




 If you want to delve into levels of nerdery you had no idea existed, go here for tests on batteries, chargers, torches etc. More for flash-lights here on the Candlepower forums.

Remember with the batteries used above. Some people regard them as incendiary devices. Do not put them on charge and leave the house!

Another really cheap and possibly more more useful scenario is to use an AA powered Fenix LD22, as used as a spare head torch by Josh Kato in winning this years Tour Divide.

Try this.

1. Fenix LD22 torch
2. 1 x 4 or 2 cell NIMH USB powered charger
3. 2 to 4 Lithium batteries
4. 2 to 4 rechargable NIMH batteies
5. Top up at gas stations on route if all the other AAs run out.

If you were wanting to try this option, the first step would be to get one of these torches and trial it first.
