The Shimano Ultegra FC-R8100 12-speed chainset offers an ideal balance of light weight and stiffness, making it the perfect choice for both enthusiast and competitive riders. The HOLLOWGLIDE structure cuts weight yet maintains strength for better power transfer and quicker, more precise front shifting. It features HollowTech II cold forged 4 arm hollow cranks evolved for maximum rigidity while reducing weight. The chainring teeth are developed to work in conjunction with 12-speed HG chains for increased contact, providing greater efficiency and improved power transfer. The wide gear pitch spacing increases clearance between the chain and leading teeth for compatibility with frames having an Over Locknut Dimension (O.L.D.) of 135 / 142 mm. A wide range of chainring options and crank arm lengths are available to meet the needs of all riders and racing disciplines. The integrated bottom bracket uses wider bearing placement and a larger axle diameter for increased stiffness and efficiency. The bottom bracket seal design has minimal bearing interface, ensuring smooth rolling and increased durability (sold separately).
