9 speed Tiagra STIs
Tiagra rear mech (not sure on the exact model, I don't think it's a long cage)
Tiagra front mech (double)
48t & 34t chainrings
12-27 cassette
I have the possibility of some riding with proper climbs in the not too distant future and after blowing out my knee last summer want to increase my range without fitting a triple and having to change my shifters. I figure a 34-32 ratio would make climbing a fair bit easier than 34-27.
What (apart from the cassette) would I need to change to fit an 11-32 or even 11-34 cassette? Thanks.
