My suspension fork isn't doing the whole suspension thing very well anymore. Things were working fine until last night...
Last night I decided to do a quick ride after putting the kid to bed, and it turned out to be a pretty nice one for a while. But then after going through a small rock garden my fork started to make this nasty clunking sound, and it kept locking up over bumps instead of compressing.
I stopped riding and pushed down on the front of the bike several times to try to compress the fork manually. Sometimes it would lock up and not compress at all (but not like normal lockout---this time it had a harsh sound/feel to it). Sometimes it would compress okay but make a squishing(?) sound. And sometimes it would completely bottom out with relatively little resistance.
During the very slow ride back to my car, the fork was clunking continually and not compressing over bumps.
So, is my fork done for? I'm taking it into the shop today, since suspension systems are the one part of bikes that I know very little about. I'm sure they'll tell me what's up, but I wanted to arm myself with some opinions and knowledge before going in. Any help would be appreciated.
