Hi all,

I'm thinking about getting the new UT centaur crankset 39/53. I want to put it on my cyclocross bike with already has a 2006 centaur drivetrain...except for the crankset...of course.

I have the feeling that 53/39 will be too much for cyclocross, especially that I run an 11-23 cassette. My question is: Is it possible to switch the 53 outter chainring for a 48 (48/39 configuration)? If yes, where can I buy them?

Eventually I could also put a 13-29 cassette.

Thanks for your input.
