Shimano Ultegra R8000 Chainset

• Shimano's R8000 series chainset brings you the exceptional styling and efficiency of the top-tier Dura-Ace and makes it more accessible to all riders. Featuring lightweight crankarms, a hollow outer chainring and a wider gear pitch, the R8000 chainset offers optimal power transfer without weighing your bike down.
  The HollowTech II 11-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 11-speed HG-EV 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
  Wide gear pitch spacing increases clearance between chain and leading teeth to provide compatibility to frames with O.L.D. 135 / 142 mm and 410mm chain stay length
  A wide range of chainring options and crank arm lengths are available to meet the needs of all riders and racing disciplines
  HollowTech II integrated bottom bracket uses a wider bearing placement and larger axle diameter for increased stiffness and efficiency
  HollowTech II integrated bottom bracket seal design has minimal bearing interface ensuring smooth rolling and increased durability (sold separately).
