Keeping your bike shifting with crisp precision, the Shimano HG 091 11 Speed Chain represents the very best among Shimano's line, pairing brilliantly with the brand's top flight XTR and Dura Ace 11 speed drivetrains. New for this year, this chain features a revised plate profile that's compatible with E bikes and single speed applications. This design makes it no longer vulnerable to separations in the aforementioned applications, withstanding higher torque generated by E bikes. Slight asymmetry pairs perfectly with Shimano's 9000 series drivetrains for silky smooth gear shifts and greater power transfer. The low friction SIL TEC treatment glides across your cassette's cogs with minimized friction. Ultimately, this allows you to focus on riding without worrying about your chain keeping up with rapid shifting and high cadence efforts.
