Ain't gonna bump with no...
My old Manitou II fork's urethane bumpers have hardened up to the point that I have a rigid fork. I have been trying to find replacements for years. Any time I do (usually on eBay) they sell for more than the fork is worth.
Well, I found a substitute!!! I am not going to tell just yet, but they fit in the fork and seem to be working. I just have to try some different densities to get the right feel. I will be riding on Sunday and will report what I have found.
Hope springs eternal!
