Convert to compact crankset?
Hi,
I'm currently running a 53/39t Shimano 105 5700 drivetrain on my road bike, and plan to do some serious climbing this year. I've done 14-15 % climbs with this gearing (mostly shorter climbs), but in this area, you can climb 100 ft for every 10 mi ridden. Would it be beneficial to go with a compact crankset?
Would it be possible without changing derailleurs/shifters? Got a 11-28 cassette in the rear.
