Howdy.
I have a standard Shimano 105 group, including STI brifters and 52-42-30. As my age in years equals the number of teeth on my large chainring , I find I want a serious granny, like a 26. But since both front and rear shifters are indexed, I'm thinking that I'm locked into these specific chainring sizes. True?
I know it's not an FD capacity issue, b/c I have another ride (but with SRAM twist shifters) where the same 105 FD handles 50-38-24 just fine.
An alternative I'm also considering is a 46-36-26 touring crankset. Any hope of the 105 STI brifters working with these? Thanks. Peter.
