Product Details

The R7100 2-speed crank brings maximum power transfer efficiency to your road bike. At the same time, shifting is as fast and precise as usual. The crank weighs only about 50 grams more than the comparable Ultegra model, which is mainly due to the hollow-formed aluminium crank arms.

Thanks to the Hollowtech II design, which has been tried and tested for years, with a fixed 24 mm axle, the ratio of stiffness, performance and weight is just right. The small chainring is made entirely of aluminium, while durable composite is also used on the large chainring. FC-R7100 has an asymmetrical 4-arm bolt circle diameter of 110 mm.

  • Perfect balance between stiffness, stability, weight and rotational efficiency
  • Optimised power transfer
  • Fast, high-precision shifting at the front
  • Hollow crank arms (Hollowtech)
  • Anodised crank arms and chainrings
  • Stainless steel chainring bolts
  • Chainline: 44.5 mm
  • Q-Factor: 148 mm
  • Compatible BSA Shell Width: 68 mm
  • Recommended Bottom Bracket: BBR60 or BB72 Press Fit Hollowtech II (not included)
  • Recommended Chain: CN-M7100
  • Weight: 170mm 34-50: 754g
