Hey folks,
I recently joined this forum, but I have been lingering for quite some time. That is, until I ran into a problem that wasn't addressed by one of your tutorials. I recently changed the chain on my 70s era schwinn varsity. It was badly stretched, but before getting into bike maintenance I didn't even know that this was an issue.
when I replaced the chain I was careful to insure I didn't create any tight links in the chain. The new chain rode through the gears beautifully when upside down and working on it. however, when I went outside the chain began jumping the flywheel. It did not shift up or down, but simply skipped. This happens more than once per revolution when going up hills. it happens on all gear combinations, but particularly the higher gears, where there is more load on the freewheel
I went back to the LBS who sold me the chain and they blamed my ignorance on how to install a chain. After checking out the chain and admitting there was nothing wrong with how I put the chain on, they told me that the old chain meshed with the freewheel and they wore together. He said that it is then likely that if I go to a new chain, it won't mesh with the old flywheel and I will have to replace the flywheel as well. This will cost 35$ to replace my 5 speed freewheel.
My question is - is this guy yanking my chain? This seems less than plausible to me. the wear on the freewheel is minimal, and the teeth still have largely squared off corners, although I can't say how many miles are on it, or when it dates from. is it possibly a chain - freewheel compatibility issue? I have a Sugino crank, a schwinn front derailleur that looks original the bike, a shimano rear deraileur, but I can't tell the brand of the freewheel.
I tried recycling a 6 speed freewheel bringing it to the LBS to put on, but he said my axle was too short. even after putting some washers? on it.
any help is appreciated
