Tour bike drive train problem
Bike: 1984 Trek 520, just rebuilt with my hardrocks drive train, sram x-4 derailer, mountain triple up front (but no front derailer), 8 speed chain, quill stem friction shifter, I have not transferred my cassete yet, and have been running it on a 5 speed free wheel (untill i get my next paycheck), it shifts bad/can't find the sweet spot/buzz's. Is this because the 5 speed free wheel is different then the 8 speed cassete (that was part of my hard rock)********************????
Also: I possible could afford to take a link or so out of my chain, but ill ask for LBS for their opinion on that, and I need to learn more about fine tuning my derailer! |

if you can't dial in a sweet spot, then maybe you have serious chainline issues. i can't thing of a reason why you can't adjust your friction shifting to get in a sweet spot. perhaps you need to adjust your b-screw?

I doubt it will help with your problem but you should shorten your cable housing a tad.

Did you reset the limit screws on the rear derailler when you swapped it over? They would need adjusting regardless of whether or not you were still using an 8 speed cassette.
