Less wasted (too) tall gears in exchange for a more useful lower gears.
Do you think I am I cutting off too much top end by going with 48/34 & 11/34? I would probably need to replace the crank which I'm contemplating anyways. I'm not using this as a commuter, I'm riding to be as fast as possible. My normal adviser sent me to sheldon's gearing website, but I am not fully understanding all the data. You may not have the information you need to answer that, but any help is appreciated.
