I popped up to Carmarthen branch today to pick up a set of pedals for grandson's bike, as well as a new chain to replace the snapped one on my tourer thing. So I cleaned the chain and took it with me, asked the guy at the desk if he had a replacement. How many speeds is it? He asked? Er, dunno 18 I think. Well he said, "the no of speeds is the number of sprockets on the back, the front one is just to line up the chain with the back set"
Well, if this is the case, surely the crank sprockets would all be the same size?? Is this a classification thing?
The one thing I agree with (which I never knew or thought about tbh, is that the chain width is dictated by the nymber of sprockets on the back. At second look we had the correct looking chain, I asked if he had a vernier - no, so eyball it was.
