The XTR/Dura-Ace CN-HG901 Chain keeps our bikes shifting with precision, and pairs brilliantly with Shimano's top-notch XTR and Dura-Ace 11-speed drivetrains. This model features a revised plate profile that's compatible with E-bikes and single-speed applications. 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.
