What is the maximum size large ring that anyone has got away with on a Tiagra 4703 triple?
Shimano says only 30/39/50.
But based on past experience I know that I can usually get 22 or even 24T capacity, but that the middle/outer ring gap needs to be preserved. Ideally i would like 28/41/52. Anyone think it would / would not work?
It's for a tandem and I want as broad a range as possible as the guy it is for wants to do both hilly-ish club rides and the odd TT.
