So theres no real benefit of the 1:1 ratio over the 1:2 ratio, other then being "unique" (read; more proprietary parts to buy during upgrade/downgrade)..?
Thinking logically, it would seem a larger ratio, would be more beneficial, easier to shift (less thumb/fore finger movement, allowing more leverage), would use smaller shifting mechs/pods, and would aid in faster shifting from cog to cog (1mm of shifter movement = 2 or more mm of derailer movement). Am I missing something here?
