I picked up a nice little Trek 830 (pearl white, nice condition. she's a beaut) and was going through sorting it out. I'm adjusting the derailleur and notice the chain hopping up and down. I first think it's a stiff link, but realized it occured too often and caused no other issues. Then I'm thinking the chainring is bent/warped, but the big one is round still...
I'm decently mechanically inclined, but this was really messing with my brain. Not round, but no evidence of bash damage. For a brief moment I was picturing the gorilla that must have put enough tq. on these poor rings to warp them like this....people really should warn a guy about these things.
Oh, they are Suntour XCE cranks. I found a minuscule amount of info on these. Basically that they are from '89. Anybody got some info?
