Shimano's 105 FC-R7000 crank arms bring Hollowtech II integration to an 11-speed road groupset, pairing a 24mm aluminum spindle with a stiff, lightweight arm design. Supplied in a 165mm length, this pair accepts a 9/16 inch pedal thread and is sold as crank arms only, without chainrings or a bottom bracket included.
The crankset uses Shimano's 110mm Asymmetric 4-arm chainring mount with a 4-bolt pattern, compatible with 53-39T, 52-36T, or 50-34T chainring combinations across 11-speed, double-chainring drivetrains. A wider gear pitch increases clearance around small chainrings on modern 135mm O.L.D. frames, allowing use of larger-volume tires without added frame interference.
