I'm not exactly hard to find!ColinJ?
I have been away from cycling for a long time and am replacing my vintage racer with only 1 front sprocket, with a 27 gear bike & 3 front sprockets. Is it a common occurrence for the chain to fall off in bottom gear? I ask because if I 'break down' and can't fix it myself I physically can't walk to get help/home, so this issue is worrying me a bit.
I've seen chains so firmly wedged down between the little ring and frame that they couldn't be released without the use of heavy duty tools and were destroyed in the process.No, but if you do drop the chain, just put it back on again!
