Front wheel shudder on Cyclocross brakes I have a Javelin Primitivo with cantilever brakes. My front fork is carbon.



When I brake the front wheel will "shudder". I replaced my wheels and adjusted my brakes (toed them in). I have even tried my road bike wheels.

Any thought on solving this? I would like to upgrade my brakes but I want to keep the option for my wide tires.
The stutter comes from the way the brakes are actuated. From the picture on Javelin's site I see that the housing is held at the top of the head-tube. When you brake the fork flexes backwards causing the cable's tension to change. The brakes will be slightly released causing to fork to move again, re-tightening the brakes, pushing the fork backwards. This happens in quick succession thus the brake stutter. The way to cure it is to move the attachment of the cable-housing to the crown of the fork. There are front cable hangers that can be screwed to the hole where a side-pull brake would be attached.
