I'm having trouble with front brake chatter on my CX machine. 1-1/8" Kinesis crosslight fork, tektro shortie cantilevers WTB ball bearing threadless headset. I've tried 3 different sets of brake pads, 2 different wheels (each with a different rim) and toeing the pads. Extreme brake pad toe in improves things, but the amount that I have to angle the pads is rediculous, and I loose a lot of power. Any ideas?
