So I slapped a 11-34 XTR cassette with my shimano long cage rear ultegra derailleur and ultegra shifters,
I've been reading the forums and they say that is not possible.
I've ridden it about 50 miles around in the lowest 34 gears and don't seem to have problems. My question is am I damaging the components? Why are people saying this isn't possible?
Thanks in advance,
