I've got an odd chain skip problem, I was hoping someone might have some input to share.
I just got an awesome, older 7 speed Trek 950 Singletrack from the thrift store that skips under load. I gave it a new 7 spd chain, a new 7 spd RD, and a thorough tune up and cleaning. Cassette teeth are sharp and clean, not rounded off. New shifter housing and cables, everything tensioned and shifting like butter. Hanger does not look bent and it has all compatible LX components for this part of the drivetrain.
The old RD looked fine but swapped it to make sure it wasn't the problem. Still skips.
Pawls are engaging. Made it a singlespeed on the cog ratio it skips on, and everything engages just fine.
The search function is great, I learn a lot around here, but this has me stumped.
I've spent hours and hours on it, I'm about to take it to the 15 year olds at the lbs to see if they can do anything.
I guess my question is: What else COULD it be? Thank you!
