Does anyone do a 12 or even 13 or 14-40T cassette?
Trying to get some easier gears on a Tiagra 4700 groupset with a GS rear mech. 50-34 front so a 11-40 (with road link) would put it at 45T when the capacity is 41T.
Will it work ok past capacity or if not, is there a cassette out there that starts at 12 or higher? Top end speed is not an issue and it's not my bike so I really don't want to have a situation where is a risk in certain gears.
if the crankset is 4700 as well, you could look into getting some oval chain rings instead - someone (I think Doval maybe?) does a 46-30 for compact 4-bolt. If that's not an option for you, then 46-34 with an 11-40 would be my suggestion as well.
