The Shimano HG601 105 5800 11 Speed Chain is a super narrow lightweight 11-speed HG-EV symmetrical design chain for smooth shifts and maximum durability.

The outer plate design has been developed to reduce the chance of chain suck and Sil-Tec surface treatment technology (PTFE plating) on Zinc Alloy inner and outer links and rollers make sure the chain stays running smooth and increases durability. The inner plate has been developed for better contact with gears providing smoother shifting under high load, giving efficient pedaling, increased rigidity, and near-silent running.

This chain has a total width of 5.62mm, optimized for 11-speed Super Narrow HG-EV drivetrains to give its full potential and can now be used with the higher torque generated by E-Bike drivetrains.
