i just picked up a 96' rock shox judy xc fork at my local bike shop for $50 bucks they have never been used but have been at the shop for a while, i put it on my bike and they seem really stiff, so i took out top and it isnt even a spring, it is like 5 hard foam cylinders. are these shocks supposed to be stiff? can i somehow soften them up? or should i just try to return them at my shop?
