It increases long-term durability by up to 300% over Hyperglide. This slows drivetrain wear, which results in more stable gear changes through extended use.HollowTech II cold-forged crank arms: The arms use a proven forging process that improves rigidity under load. This cuts unwanted flex during pedalling, which leads to steadier power transfer.Hollow forged and anodised aluminium crank arm design: This construction removes excess material while maintaining structural strength. It lowers overall weight and holds stiffness, which results in a firm and controlled pedalling feel.Option to use external or press-fit bottom brackets: This setup gives freedom during installation and service work. It makes fitment straightforward, which leads to easier tuning and long-term maintenance.Alloy outer ring paired with a steel inner ring: This mix uses the light weight of alloy and the wear strength of steel. It keeps shifting clean and extends ring life, which results in dependable performance in mixed riding.47mm chainline set for 142/135 mm O.L.D.: This chainline aligns the rings with LINKGLIDE or HG 11-speed chains. It reduces cross-chain friction and helps maintain clean shifting, which results in a smooth and stable drivetrain feel.This chainset aims at riders who want solid long-term performance with minimal fuss. The LINKGLIDE system helps with consistent shifting over many miles. The forged crank arms support steady load handling, and the chainline setup works well across common frame standards. Together, these features back a drive unit that holds its performance over time without complex upkeep.If you want a chainset that brings strong durability, clean shifting, and simple setup to your build, this model is ready to slot into your drivetrain and support reliable everyday use.
