Shimano's proven 105 group is full of trickle down technology from the Ultegra and Dura Ace lines. It's an outstanding value, and the crankset is no exception. The Shimano FC 5600 crankset uses the Hollowtech II process to create an ultra-stiff power transfer machine to get the go-fast from your legs into the wheels. It's a smooth shifting, superlight crankset that's ready for everyone from racers to weekend warriors.
