Old DA 9 speed shifters (left), much closer to bar than "aero" levers (right). |
If you are serious about off-road riding then you will likely want the brakes more forward on the bar so you can access them when on the drops.
If you are more inclined to be gravel grinding or bike-packing then you are likely to want them to be higher on the bar, so you can make use of the different positions available. This was one of the main reasons I didn't use my Karate Monkey on the Kiwi Brevet, with my smaller digits its a real reach for the brakes while on the drops, and it causes me a pressure point after about 3 hours riding. This pressure point is in the very same spot on my hands when I rest my hands on the hoods.
A couple of views on how you could set up your drop bars.
- Drop bar set-up by Guitar Ted.
- Matt Chester on drop-bar set-up.
- Jason Boucher's tips on a Salsa Woodchipper.
- Shiggys why-for.
Obviously I had to swap my MTB-pull Avid BB7's with the Road-pull version. My next move will be to bring them further down the bar to see where the best position of compromise is. (I did - see below).
I have just discovered the pitfalls of trying to use STI road levers on an MTB. Its a bit of a mess.
The rear derailleur is sweet. On the front, unfortunately STI levers only pull 69% of the cable that an MTB lever pulls, so STI levers and MTB derailleur on the front is not really compatible.
- MTB's all use top-pull derailleurs.
- Road bikes all use bottom pull derailleurs. Suck.
What are the alternatives? Surprisingly few.
1. A pulley device for changing the direction your cable comes from Problem solvers.
2. Another device to change the direction from the speen.de guys, (good luck trying to understand it). A better description here.
3. A special top-pull road-style derailleur made for CX application.
4. I just tried this one, and its 99% successful. Clamp the derailleur cable on the other side (back-side) of the bolt. It effectively shortens the lever, giving more pull. Not all derailleurs can be tweaked this way.
A very good link to derailleur stuff.
See here my drop-bar set-up with the bars rotated forward so I get a much more comfy position for my hands and wrists while on the drops. The more horizontal the drop is, the better my OOS afflicted wrists like it.
Also note how the drops themselves are less than 2 inches below the flats on my standard XC bike (Santa Cruz Superlight), and that is with the stem in the positive position on the Superlight. If the stem was flipped they would be identical. Not at all aggressive.
Okay. My top-pull CX-70 Cyclo-cross front derailleur has arrived! It really works a treat. See below.

Well there is another option for running integrated shifters - SRAM - although that's probably not the answer you're hoping for.
Rival/X9 was my groupset of choice for my surprisingly similar build!

Hey there, yes I heard that sram road and mtb cable pull was the same ! Good on them.
Hi Jeff - I found pics of your KM on mtbr then happened upon your blog. I have a 2007 KM frameset (16") that is currently attached to an Xtracycle cargobike kit. I'm planning to switch to a new cargobike setup in November and build up the KM as a rigid dropbar 1x8, my first real mtb! Your notes on sizing and frame fit have been really helpful as it sounds like we are similar in stature. I ride a 54cm Cross Check for cyclocross and proper fit has always been difficult for me to achieve. Thanks for posting. Cheers -
