Shimano Ultegra R8000 11 Speed Chainset

Shimano Ultegra HollowTech II 11-Speed Chainset

The Shimano Ultegra HollowTech II 11-speed chainset delivers an ideal balance of low weight, stiffness and shift performance, making it a perfect choice for both enthusiast and competitive riders. The HollowGlide hollow outer chainring virtually eliminates flex, significantly improving rigidity and delivering crisp, reliable shifting even under high load.

Chainring tooth profiles are optimised to work seamlessly with 11-speed HG-EV chains, increasing contact for greater efficiency and improved power transfer. Industry-leading HollowTech II cold-forged hollow crank arms maximise rigidity while keeping weight to a minimum.

Wide gear pitch spacing improves clearance between the chain and leading teeth, ensuring compatibility with frames using 135 / 142 mm O.L.D. and 410 mm chainstay lengths. A wide range of chainring sizes and crank lengths allows riders to tailor the setup to their discipline and riding style.
