Any question answered...

I have a ten speed Shimano groupset so 10 speed chain, but the only crankset I have is a 2300 8 speed. Is this going to work? Are the teeth really going to be too wide to fit into the chain? I am not at home, but just realised the mismatch - when I get home I will try the chain to see if it does fit. BUt even if it does, will it work properly?

Possibly, depends how wide the chainring is on the 8speed crankset. Wrap the 10speed chain around it and see if it binds?
