I have a '04 Trek 520 with a Bontrager Fairlane A-Sym rear rim and v-brakes
with pink Kool-Stop pads. When I apply the brakes, they grip harder every
time the pads go by the portion of the rim where the valve is. So when I
break, the bike goes thunk, thunk thunk each time the wheel goes around
until I come to a jarring stop. It's very annoying. So I figured the
obvious- that there must be a bulge in the rim where the valve is. I put it
on a trueing stand. I checked and double-checked. There is no bulge- the
wheel is true. It's as if the metal near the valve has a different
composition or something, so that the brakes grab it more in that spot- but
there is no bulge. Has anybody experienced anything similar?
