Keeping your bike shifting with crisp precision, the Shimano XTR/Dura-Ace CN-HG901 11-Speed Chain pairs brilliantly with the brand’s top-flight XTR and Dura-Ace 11-speed drivetrains. It represents the very best among Shimano’s line, which puts it in the running as the best chain, period. This year’s model features a revised plate profile that’s compatible with E-bikes and single-speed applications. It’s no longer vulnerable to separations in the aforementioned applications because it’s able to withstand the higher torque generated by E-bikes. The chain’s slight asymmetry pairs perfectly with Shimano’s 9000 series drivetrains for silky-smooth gear shifts and greater power transfer, and the low-friction SIL-TEC treatment glides across your cassette’s cogs with minimal friction. Ultimately, this allows you to focus on riding without worrying about your chain keeping up with rapid shifting and high-cadence efforts.
