The chain on my old S-10-S skips and I can't figure out why. I rebuilt the bike myself and have done some work to fix the problem. First, a new freewheel thinking that the skipping came from a worn out old one. That was accompanied by a new chain as the old one was fairly close to worn out.

Result: Skip skip skip.

Checked rear drop outs and wheel alignment. No problem with the drop outs, but the wheel was not as "true" as it could have been when tightened down, fixed that.

Result: Skip Skip Skip.

As the bike is friction shift, all I can think is that the LBS may have pulled a chain for a bike with more than a 6 speed freewheel, leaving me tolerances that are too close. I plan to check out that possibility with the LBS on Monday.

Any other ideas? I really want to beat this as the bike is a sweet ride otherwise.
