I've seen a few threads on 10 to 9 speed compatibility but none that really cover this.
I'm thinking of buying a Shimano 10-speed dynasys M770 crankset (on special but also because I need it in 165mm length for my son) but it says everywhere it is not compatible with 9 speed drive train. At most I would think I might need a 10 speed chain (as that has been shown to work on 9 speed cassettes) just in case there is some special ramping and chain matching going on. Does anyone know what the 10 speed cranksets are not compatible with? Chain? Chainline? 9 speed front derailleur?
