The Shimano 105 FC-R7100 crankset brings 12-speed road performance within reach, pairing hollow-forged alloy arm construction with Shimano's refined chain management geometry for efficient, consistent power delivery.

  • Hollow-forged alloy arms reduce weight while maintaining the stiffness needed for efficient power transfer
  • 12-speed compatible, designed for use with Shimano 105 R7100 and Ultegra R8100 groupsets
  • Gloss black anodised finish for a clean, durable aesthetic
  • Resin-ribbed chainring backs provide structural support while minimising chainring weight
  • Optimised chainring profiling for fast, accurate Di2 and mechanical front shifting

Shimano 105 has long been the benchmark for value-focused road performance, and the FC-R7100 upholds that reputation. The hollow alloy arm construction uses Shimano's forming technology to create a crank that is both light and rigid. The redesigned chainring profile works in concert with 105's front derailleur geometry to deliver crisp, predictable shifts under load — whether on flat roads or steep climbs.

Compatible with Shimano 105 R7100 and Ultegra R8100 12-speed road groupsets. Requires a Shimano Hollowtech II-compatible road bottom bracket. Available in multiple crank arm lengths and chainring size combinations — confirm your frame's BB shell type before purchasing.
