I have a road bike that was converted to single speed with a single sprocket on the read wheel and a single chainring.
I had a 3/32 chain which worked perfectly fine. However after many kms and apparent chains stretch I decided to replace the chain.
I replaced the chain with a single speed 1/8 chain which I assumed would work perfectly, given that there's a single sprocket and chain pitch is standard.
All modern bicycle chains are made to the “one-half inch pitch” standard, meaning from rivet to rivet is nominally 0.5 inches. The sprocket teeth are cut for this same one-half inch standard to accept bicycle chains. However, this does not mean all makes and models of chains are interchangeable. source
Since I replaced the chain, the chain skips on the rear sprocket due to what appear to be misalignment which compounds after a couple of revolutions and then skips.
I tried adjusting the chain tension but that doesn't seem to help.
Hypothesis to explain the problem:
- The stretched chain had deviated from standard pitch and caused the sprocket (which is relatively old) to match it through constant wear.
How reasonable is that? Should I just replace the sprocket? Could the problem be elsewhere?
