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)
All-mountain SLX HollowTech II chainset is tough and aggressive yet also lightweight and excellent value The HollowTech II Chainset features hollow forged crank arms which are both lightweight and rigid whilst being incredibly strong and durable HollowTech II integrated bottom bracket design uses a wide bearing placement with a large axle diameter for increased stiffness, efficiency and added durability 70 degree spider arm for optimal rigidity 36/26T combination 12-speed chainrings We recommend that the bottom bracket is initially installed by a bike shop to ensure perfect facing and fit For use with 12-speed HG MTB chains only With a 48.8mm double ring chain line for use in conjunction with 142 mm O.L.D.
Features:Dynamic Chain Engagement (DCE) is used to hold the chain and help prevent chain jump out. This is achieved by using a broader and taller tooth profile in conjunction with a special hooked leading edge and alternate profiled tooth shaping.
