The hills are alive...




We discovered this new hill in Wellington the other day, in Wadestown, "Weld St" . Dang it was steep... you cant tell from the photos, but I felt ill riding up it, as short as it was. The last photo is from out near Makara beach. Much less steep, and more scenic.

Assembling kit for Oz masters world track champs

I got an axle kit from HED, to convert this old screw-on clustered disc into a fixed wheel for the track. It worked a treat! It was easy as to set up. I havent tried it out yet, the velodrome is probably a bit slippery at the moment. Hmmm bugger.... have just found a flaw with the HED kit. It only has the one set of threads, and there is not much room for a lock-ring.... which means I cant use the clever Miche styled carrier system I just bought. You can slip a very thin lock-ring on if you are using standard cogs, but its threaded the same way anyway, so its just for decoration. A trick for young players.

My buddy Humpy has lent me his Raceline Record with Miche crankset, so that should be a bit faster than my old "Pex" . A couple of new chains and some bars and I should be rocking.

I will put a negative rise stem on to improve my cda. Its easier than making more watts. I have an idea on what kind of watts I will need to be competitive, and its another 70 watts over what I estimate I made at the nationals. I am not sure how easy it is to grow another 70 watts for 3kms but I will be monitoring my progress closely with the power tap.

New toy just arrived...

Power tap Pro.
Looks a bit like an SL, but its not.
Compare
The Saris guys are amazing. They certainly stand by their product. Awesome to know this when you live thousands of miles away from their HQ. These babies look totally different inside to the old yellow model pro. It has little hearing aid type batteries instead of the bigger half AA sized ones.


The weight is very similar to the old yellow pro though, despite the shiney carbon : ) - well, it was on my kitchen scale.

Dynamic Composites Zen Disks


I really liked the look of these wheels while at the the Track nats this year so I took a few shots.

Apparently their offical launch is coming in the next few months. Stay tuned.

A commute route I often take to get to work

This is a commute route I often take to get to work. I live about 2kms from work, and its all downhill. Good for 14 calories of expenditure according to my power tap. So some times I start by carrying on up my hill until I reach the Danzig MTB track built by the local MTB club. If I ride down it, then back up again, and back down my hill, its a good 60 mins of single-track fun.

A lunch time ride in the Hutt Valley

This is a lunch time ride for us here in "The Hutt". It takes in Moonshine Hill and can be done at a firm pace of 1 hour and 9 mins from my place of work. It has one of the steepest climbs about and I think it is about 15 %. Check out the location map if you are a Lord of The Rings fan. For a hell of a long time the set for the battle scene of Helms deep was sitting in at Dry Creek Quarry at the bottom of Haywards hill.
You could see if from the road, I guess I shoudl have taken a picture? A lot of this stuff is lying around in back-lots in Wellington as they dont really know what to do with it. What do you do with giant polystyrene monsters and buildings.They filmed the downtown scenes for King Kong behind my wifes work in Petone, but you couldnt see a thing. Amazing the tiny places they can sneak a movie set into.

Flying Scotsman movie

I saw the movie last night. The Mrs was using the car carting the kids about, so I had to ride my bike into town to meet the folks I was going with. I thought it was apt that I should ride my fixer so by the time I got to their house at the top of Brookyn Hill my legs were seriously munted.

The guys I went with were not cyclists at all, but they loved the movie. Its been playing for 3 days now in Wellington, altho there were only about 10 of us in the theatre last night. Many cyclists have said to me that its their favorite movie and it would be the best cycling movie I have seen too.
The movie manages to come across in a really balanced way that has appeal to the man/woman on the street and still manages to appeal to the hard core cyclist. The UCI (called the WCF in the movie) get pretty demonised, but everyone else comes out pretty well. Chris Boardman comes over as a genuinely good sportsman which is pretty much the feeling I got from reading the book.

The topic of depression is dealt with very well. Its always there in the background, but doesnt overwhelm the movie. With 1 in 5 people in this country being afflicted at some stage in their life its a topic that could do with more coverage. I am sure Graham isnt the only athlete to have suffered.

The movie seems to finish quite abruptly. There was a lot more that could have been put in, but it would possibly have ended up looking repetitive in the end, as it was more of the same. Wins more, position banned, more downers etc.

I would definitely recommend it as a great movie to watch, for cycling fans, and non-fans. Maybe the non-fans would enjoy it the most, because they will know less about it, and be gobsmacked at the way things happened. The people I went with were.

As usual, a movie never matches up to the book, but thats a tall order in 105 minutes. The best way to do it would be movie first, then book.
Its an awesome book, and a great movie.

DIY aero testing

DIY aero testing.

The goal.
To see if there is a measurable difference in "aero-ness" between using my new aero lid, and using my old standard helmet.

An increase in "aero-ness" is crudely defined as the ability to do the same speed for less watts.

The location.
Outdoor velodrome at Haitaitai, Wellington NZ.
333 metre concrete track. (Bumpy).
Wind . Nil.
Temperature. 9-11 degrees.
From around 8am onwards.
Barometric pressure 1026 hpa.
Humidity 80%

The format.
8 runs. Completed in 1 hour and 15 mins with very little resting or downtime, apart from swapping helmets and noting temperature. Aero means Aero helmet, non-aero means non-aero helmet.
4 x 5 mins at 34 kmh. Aero, non-aero, aero, non-aero
2 x 5 mins at 40 kmh Non-aero, aero,
2 x 10 mins at 35 kmh. Aero, non-aero(35kmh seemed easier to do than 34 kmh)

The difficulities.
1. Getting the track to myself. (No problems)
2. Getting consistant wind . (No problems)
3. Getting consistant temperature. Pretty good.
4. Riding at a consistant speed. Way better than a previous attempt. The trick was to ride by feel (cadence?), rather than obsess on watching the computer.
5. Getting a smooth line. I rode on the sprinters line because it was way smoother than the bumpier pursuiting line. I guess this means I am less vertical than I could have been.

The equipment:

1. Bianchi d2 chrono TT bike and Power tap. Deep front rim. Weight around 9kgs
2. Carrera Dragon Fly helmet (Non-aero)
3. Louis Garneu Rocket helmet. (Aero)
4. Rider about 71 kgs. Add another 3 kgs for kit at least.


The "raw results"" are as follows, and have had no factors applied to them. They are listed in the order that they were undertaken.

Run number:
----------------------------------------------------
1. Aero. 5mins 34.6kmh 191 watts temp 9.3
2. Non-aero 5mins 34.5kmh 194 watts temp 9.9
----------------------------------------------------
3. Aero 5mins 34.7kmh 196 watts temp 9.4
4. Non-aero 5mins 34.5kmh 197 watts temp 9.8
----------------------------------------------------
5. Non-aero 5mins 40.2kmh 280 watts temp 9.9
6. Aero 5mins 40.5kmh 270 watts temp 10.9
----------------------------------------------------
7. Aero 10mins 35.1kmh 195 watts temp 11.4
8. Non-aero 10mins 35.3kmh 197 watts temp 11.4
----------------------------------------------------


To try to get an smooth transitition from start to finish, I would set my timer off for 5 mins, take two laps to settle in, then go another 2 laps after my time had elapsed, and stop pedaling on the line.

At the end of the day, after downloading this data, I would then "select" 5 mins worth of data, back from that coasting point, so all tests at least stopped in the same place.

The differences I recorded in the 40kmh test were pretty major, compared to the lower speeds, but I guess I would have to do it a couple of times to see if they were consistant and not some kind of an aberration. I think the last two runs are the least impressive as far as being decisive in any way, as the last run was actually faster than the one before it. If I am doing it right, I get a CdA of .233 using Alex Simmon's spread sheet. I am not sure if that is good or not.

07 NZ Track nationals


I was pretty keen to do the NZ track champs when I heard that they were going to be held in the new covered velodrome in Invercargill, but totally dismissed the idea after Kay's job came to an end in December. I knew it was an extravagance we couldn't afford.

Rachel rang the weekend before the track champs started and asked if I would be interested in driving the van loaded with bikes and two young'ns down to Invercargill. Simon had wrecked his back and couldn't drive down the van! Simon was particularly gutted as he had some good form. As I would be spending 4 days driving the bikes and riders down there and back, the club would subsidise my accommodation while there. I initially dismissed the idea as my brownie point collection was not looking good. In the end my long suffering wife told me to go, as I could at least visit my Aunt who had been having treatment for her cancer at Invercargill, and I could stay with my brother on the way there and back, who also had not been well.

That next week was a pretty damn hectic. I had to prep my TT bike for the event I had actually been training for (Saturdays TT in Masterton), as well as build up my track bike into something competitive by borrowing fruity parts from most of the trackies in Wellington. Trackies are great like that. Bars, wheels, chains.... not much of my original bike remained. I also had to load up the van kindly lent to us by Marty McDonald to ferry the gear down. Bikes, wheels rollers and other inanimate objects were jammed into the back along with Nick and Troy who managed to keep me fully entertained for the 2500kms we did in the van. They unmercifully ribbed each other constantly about the size of each others legs and their inability to own up when the air turned foul. I have to admit to being worried on the way back when Nick started for the first time to eat non-processed food, eg Apples.... Nick's diet up until then had consisted solely of Coke and Subway.

The research I had done before heading south had unearthed nothing about the kinds of times I expected would be competitive in my 3km pursuit. There were no results to be found on the Cycling Southland Website. We tend to forget we probably have the best cycling club website in NZ thanks to Jonno. http://www.pnp.org.nz

I didn't race until the Friday, so I had time to try some bigger gears. We arrived at about 4pm (having left Christchurch at 7.30 am) and got on the track at 8pm on the Monday night! I started by going up 2.5 inches in my gearing and I was still spinning pretty damn fast on a 3/4 length effort. After ringing up Aaron for advice, I went up another inch in another effort a few days later.
I was now looking at splits of 18 seconds flat per 250 metre lap. This was my best case scenario. If I blew, I thought I could come under 3.46, bearing in mind my fastest time in Wellington was 4.06 . Yep, it was a fast track. At the last minute Mike Byrne offered me his Teschner with Mavic and Zen wheels on it... possibly one of the fruitiest bikes there, but I decided against it. It had taken me a week to build up my bike, and I was happy with my aero position on it. I had Aarons old rear Ghibli so that was pretty cool. Luckily I did a few laps in the morning with my contact lenses in, as they dried up with the heat of the enclosed velodrome. There was an emergency trip by Mark back to the Motel to get my specs which meant not using the visor on my new lid.

The guy who I thought would win my event was Ray Dunstan. He wins the TT in our age group every year at the Road nats... (every year except this year). Just my luck. I didn't go down to Palmerston South, but Mike Sim did, and got Rays scalp. Ray rode the pursuit just before me. I sat in the hotseat and watched him shorten the Masters 2 record by 24 seconds! His time was sharp. 3.39. It was a PB for him by 3 seconds and would have given him a silver at the world masters in Manchester last year. Ray has a duel going with NZ's current top women's pursuiter, Alison Shanks. We think he is now in front of Ali by a few hundreths!

I knew I would have to be firing to beat Ray. My splits were for a 3.41, but I would see what happened. After telling Troy and Nick that the three rules of pursuiting are....
1. Dont start too hard, 2. Dont start too hard, and 3. Dont start too hard.... I started too hard....

Not that hard, but 17's when I was supposed to be doing 18 flat. As you would expect, as I tired my times drifted up.... I wasn't dying but it was getting harder.... I was starting to think about looking for the lap board so I could see how many I had to hang on for...... BUMMER! Only one lap to go... I dug it in and was in hi 17s again... too late, it was already over. Time flies when you are having fun.... or not...
3.44.01. In the end I came 2nd and pushed Murray Steele into 3rd spot. Apparently Murray got silver in the teams pursuit at the Commonwealth Games in 82'? Anyway. My mum was watching, and apparently the guys doing the commentary were getting pretty excited as the unknown from Wellington was mowing down the local guy (Mike Lormans). I nearly caught him on the line. As vets, we didn't do heats, and he didn't medal in the end. 9 seconds seemed to be the difference if you caught someone over the 12 laps.
Jville Cycles satanic mechanic Mark Humphries did a great job of yelling my splits. Its damn hard to hear with the noise of the crowd and the wind blasting around your ears.

Going back thru my pursuit calculator, I come out with an average of 18.3 second laps, an average speed of 48.21 kmh. (Sarah Ulmers WR is about 52 kmh). It looks safe to me!

Some of the guys down there are gnarly looking old buggers. I think its the climate. They look like they are 10 years older than they really are. We are lucky we have such a mild climate here in Wellington.... shame about the wind tho! If the drome down there wasn't covered we would have been lucky to get 1 days racing in. We had rain and hail and artic winds during in the week.

We had a great time and Shane Riches and Sepp Hiribar both tore the legs off the opposition in heats and finals, once again, against guys that had represented NZ at the very highest level..... Shanes heat was scary, he just dropped them by so much. Maybe too much? They certainly would have had an eye on him for the final! He was racing some seriously fast guys that had muscles on their muscles. Shanes cooking had to be experienced to be believed. Lasagne with home made pasta! Yummmmmm.

I expressed concern to Sepp that the guy he was racing had a sprint bronze from the Commonwealth Games and would have tactics we could only dream about. Sepp told me to relax. Sprinting is an intuitive thing. Not something to worry about.
A gold and an NZ record in the Master 2 515m scratch proved him right!
Paulas efforts in the AWD were amazing too, especially since she had food poisoning the day before she raced!

Thanks to all the guys that lent us bits and supported us. There was a petition going around to get the event back to Invercargill for next year. If it was anywhere else this year most of it would have been rained out.

Cheers Jeff
