Ultegra's new FC-R8100 crank maintains the same quick, precise front shifting and efficient power transfer that Shimano riders have grown accustomed to, but with even more crank arm length options. Spanning 160 to 175 mm in length, Ultegra cranks now cater to smaller riders, triathletes, and cyclists curious about shorter crank arms. An integral part of Shimano's new 12-speed road line up, the FC-R8100 crank builds upon Shimano's legendary front shifting and transmission efficiency. With new refinements for seamless 12-speed shifting, the Ultegra crank is now offered in lengths from 160 to 175 mm, bringing performance and improved fit for smaller riders, triathletes, and riders with specific biomechanical requirements.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 ridersHollowGlide hollow outer chainring gives vast improvements in rigidity by virtually removing outer chainring flex and hugely improves shift performance, even under high loadThe chainring teeth have been developed to work in conjunction with 12-speed HG chains for increased contact to provide greater efficiency and improved power transferIndustry leading HollowTech II cold forged 4 arm hollow cranks have been evolved for maximum rigidity while reducing weightWide gear pitch spacing increases clearance between chain and leading teeth to provide compatibility to frames with O.L.D. 135 / 142 mmA wide range of chainring options and crank arm lengths are available to meet the needs of all riders and racing disciplinesHollowTech II integrated bottom bracket uses a wider bearing placement and larger axle diameter for increased stiffness and efficiencyHollowTech II integrated bottom bracket seal design has minimal bearing interface ensuring smooth rolling and increased durability (sold separately)
