dura ace cassette - how many teeth works best with 53/39 crank?
hello everyone,
im new to the forum and looking for some advise on a new cassette. i recently purchase a new set of wheelsets (reynold attack clinchers) and im looking for a new cassette to go with it. im currently using a 53/39 crank with a 10 speed 12-25 cassette. i dont have a cadence meter so im not sure which setup is idea for me. i usually ride with the larger crank up front and 21,22,23 in the rear.
i've research a lot on tri bikes; felt, cervelo, kuota, etc and they all pair a 53/39 with either a 12-25 or a 12-23. any pros or cons of the two? or maybe a totally different setup all together? a 12-27? 11-xx? is there an ideal setup for tri specific vs road racing?
would i reguire a new chain if i use a setup different from my current 12-25? any advice would be appreciated.
