I always wondered why the old Rock Shox Indy XC fork on my old KHS bike would completely bottom out when I got onto the bike. Well it looks like I figured it out. Looks like one of the elastomers (is that the right term?) has completely disintegrated into dust.
I found a website with replacement ones, but they didn't have the springs. These springs have a yellow stripe which according to the Rock Shox manual is for riders around 140-180 lbs. I'm more like 190 and would like to get the stiffer springs, but not sure if they're available anywhere.
