Your Ultegra cranks won't take a 30. You'll be buying a new crankset to go to a true compact double. I run compact doubles on three bikes.
My commuter has a chainguard+42+26 on a 130/74 BCD in front with a 6 speed 13x24 freewheel in back. My Hilsen has a 44/30 on 94mm BCD in front with a 9 speed 11-26 in back. My road bike has a 44/30 White Industries VBC in front with a 9 speed 12-27 in back. I've never thought to myself on any of those three bikes: "dang, I need a higher top end gear" On Tuesday, September 25, 2012 12:49:53 PM UTC-7, lungimsam wrote: > > My used Bleriot came with an Ultegra drivetrain.
