i have a problem like that, when im pulling up a small hill while turning, as my back tire gets close to the start of the hill and its being pushed down by the strut to stay on the ground it makes some clunkitybunk noise as the tire gets going up the hill and starts compressing the strut back together. i think its my sleeves getting caught up on something.

haha i dont know if you know what im talking about, it was hard to explain. yours do something like that too?? (if u can figure out what i was trying to say.)
