105 FC-5600 Double Cranksets with integrated spindle. Shimano 105 is great for part time racers as well as fitness enthusiasts looking for "pro-level" technology in a lightweight, efficient, and affordable package. Although it is a by-product of Shimano's premier engineering range, it offers sleek design and a great feel which gives the 105 its own unique identity.
Combining race-proven hollow forging technology and an integrated crankset & bottom bracket, the Hollowtech ll crank reduces weight while drastically increasing rigidity as well as power transfer. The crank arms themselves are hollow, which provides strength and rigidity while keeping the combined weight low. Circling this amazing crank set are SG-X chainrings.
Built with specially designed tooth profiles, pick-up spikes and ramps, SG-X enables the front derailer to shift super smooth, giving you the rider, easy, trouble free, and quiet shifts so you can focus on going that extra mile. Hollowtech II design with spindle integrated into right crank arm.
