Running with a 12-25 cassette. The 39/25 is the same lowest gear as my roadie and I have no problem with needing lower gearing, but wondering how it will fare on the 'cross racecourse.
No. I don't think so. I was running a 38 single ring last year and thought it worked pretty well.robdamanii said:I think what I'm asking is the 39 going to be a huge ring as a small ring, or should I look into finding 36t rings for my compact cranks and stick with the 48t large ring.
