Can someone confirm if using different chainring/cog combinations with the same total tooth count will not change anything regarding chain length? I think I have read something o n Sheldon's website but I can not get to find it again.
In a scatterbrained (maybe stupid?) idea of building a bike with a two drivetrain system (flip flop hub with fixed free + double crankset) in order to have one speed for general use and one speed for very hard climbs, say 41/15 and 34/22 (56 tooth count in total - gear ratios of 2.73 and 1.55), would it be achievable with the same chain length?
