| it is a "known" Numpty issue that affects some but not others. My guess has always been that it is down to have race specification brakes on long travel forks and the fact that at times you can ride a numpty gently by trailing the brakes, - which is a big no-no on these brakes as the pads glaze. I say that as the only time I experienced it was when out riding slowly through dark country lanes, - i was not sure of any of the bends so I began trailing the front brake, - few miles later judder started, - cured it by grabbing one hell of a handful of brake to the point where the front wheel was starting to let go; no more judder. I think these brakes are meant to be used in true race bike style, - late braking and pull em hard, - which perhaps does not suit the unusual side of the numpty in that you can ride it in a slow lazy way if you feel like it. |
