I have an issue with my rear wheel on my nearly nearly new Trek Hybrid 7100 which i suspect is just annoying rather than anything dangerous or serious.
I got the bike just for commuting 8 mile a day, and the odd spot of family touring and I'm liking the bike so far. However, I noticed when I was cleaning the frame that the rear wheel is 'buckling' ever so slightly when the brakes are applied.
Now, the wheel is running 100% true, I've checked and so have my LBS, so its only becoming 'misaligned' when the brakes are squeezed. Its as if the brakes are pushing it out of line. I could actually feel the play in the wheel by pulling it side to side.
So I took it back to my LBS as I suspected it was the axle or just the cones. They adjusted the cones and checked the wheel for trueness, which was fine.
Theres no more play in the wheel, but I'm still getting the issue with the wheel when I brake. Is it the brakes causing it? Is it normal? Its hardly noticeable but thats not the point - why is there lateral movement when braking?
Any ideas other than cones or trueing?
