The original Cannondale 2x9 (29/44) crankset was showing lots of wear and was not shifting well after two years of hard use. Replaced it with the FSA V-Drive ISIS splined compact crankset (22/32/44) and bottom bracket combination. The CNC machined chainrings are ramped and pinned. They look great and shift very smoothly, even under load. If they hold up, I will be very pleased with this set-up. I will post an update in about 6 months.
