I've got my commuter cyclocross bike dialed in to about as good as the I can get it, but the braking just doesn't seem right to me. I'm using a yoke+transverse cable which came with the bike, not a link cable. I've read through all of sheldon brown's pages on adjusting cantis, and tried a whole range of different yoke heights, settling somewhere in the middle.
My problem is this: I have it adjusted so that the yoke angle at rest is somewhere around 90 degrees. Both the brifters and crosstops seem to be smushing the brakes quite well against the rim so that the brakes actually get compressed, so the mech advantage seems correct. But then when I go out on the road, the stopping power when using the brifters is nonexistent, while if I use the crosstops I can stop on a dime. The brifters don't bottom out, it's just that they hit the rim and I'm squeezing hard but the bike isn't stopping.
My setup includes: Tektro Oryx cantis, Tektro RL70 crosstop levers, and Sora brifters. Also on the front is a steerer-tube mounted cable stop. The yoke is some cheapo looking thing: shown here. I could lower the yoke for more M.A., but I don't think I need more; if I do that won't it make the crosstops have too much?
What if I replaced the yoke?
