Shimano Ultegra FC-R8100 2x12 Speed Chainset 46/36T

  • The HollowTech II 12-speed Ultegra chainset offers an ideal balance of light weight and stiffness, making it the perfect choice for both enthusiast and competitive riders.
  • HollowGlide hollow outer chainring gives vast improvements in rigidity by virtually removing outer chainring flex and hugely improves shift performance, even under high load.
  • The chainring teeth have been developed to work in conjunction with 12-speed HG chains for increased contact to provide greater efficiency and improved power transfer.
  • Industry leading HollowTech II cold forged 4 arm hollow cranks have been evolved for maximum rigidity while reducing weight.
  • A wide range of chainring options and crank arm lengths are available to meet the needs of all riders and racing disciplines.
