The need for speed (taller gears)
Okay, I'm finding the current gearing on my old Giant RB is just not tall enough. The larger chain ring is 52T and a 14T on a 6spd cassette. I really would like to step the 14T up to at least a 12T but preferably an 11T. Why am I having such a tough time trying to find that gear? Is it not doable? We're talking Shimano here. Will an 11T from an old MTB cassette fit the hub? Or does it have to come off a road bike due to hub differences? Am I just not looking in the right places? Are we having fun yet?
Thank you in advance for any sharing of knowledge,
