My issue is that I live in Florida and there is basically nothing but flat or rolling courses in my season. I have a 12-25 cassette and a 53/39 crankset and yesterday during points in my race I found myself spinning and looking for a higher gear and found myself in my highest one. I guess I am more of a big and steady rider than a high spin guy. Should I just get used to a higher cadence or would it be a better idea to look into a larger crank ring a 54 or 56 or a 10-23 sram cassette for the back? Thanks for the advise.
