Why is brake judder a problem with Cyclocross bikes?
Common problem, read the article already referenced below for the extended explanation. The short version is your cross bike uses Cantilever brakes. The forces inherent in Cantis amplify the braking flex in the fork. Solutions: 1) Try different pads and/ or more toe in on the pads. 2) Move the brake hanger down, this lessens the inherent lever arm in the system that acts like a bow and arrow. The hanger is usually at the top of the head tube, lowering it down to the bottom of the head tube or the pre drilled boss on the fork drastically changes the angles. Though you may need a shorter straddle cable. 3) Get a thing-a-mah-jig and switch to V Brakes. You can’t just bolt V’s on as they require more cable movement, but there are a couple of devices out there in addition to the one I named.
