More Information

The FC-R7100 is the crankset of Shimano's 105 12-speed groupset. The crank arms are formed from hollow aluminium and finished in gloss black anodising, giving an optimised balance between light weight, stiffness and efficiency.

HOLLOWTECH II joins the bottom bracket axle to the right crank arm and uses an outboard bearing system, which cuts weight while keeping strength for better power transfer. The resin ribs on the back of the chainrings are a 105 structural design that saves weight and keeps front shifting crisp.
