Subject: RE: Crank for Road Bike The drawback of a 12-28 cassette is the wider spacing... it can make it difficult to find the "right" gear, one gear is slightly too tall, but the next one down is slightly to low... That's one of the benefits of a compact, it allows you to use a much narrower spaced cassette without giving up the low end or top end.
Personally, I would use a 50/36 combined with a 12-25 or 11-23 (depending on terrain... ). 50/11 is a taller gear than a 53/12 btw, so you're not giving up any top end.
Plus, changing the cassette is much less expensive than swapping out the crank Edited by audiojan 2013-02-10 11:47 AM
