I have a Giant Cypress 2008. It has a cheap suspension fork. I noticed some play when I applied the front brakes the other day. So with the top tube between my legs, I locked the front brake and pushed the bike.
There was no clunks or rattling, and I'm sure it's not the headset. Because when I move the bike while applying the front brakes, the lower part of the fork moves with regard to the higher part. By the lower part I mean the part below the moving portion of the fork, to which the brakes are connected.
I am sure it's the fork also because when I turn the wheel so that the handlebar is parallel to the top tube, and move the bike back and forth, the fenders (attached to and along with the brakes) move with respect to the higher part of the fork.
I've read that some play in a suspension fork is ok. But how much is ok, and is it safe? Is it fixable in cheap forks?
