• Precision Bearings - Low maintenance and simplified installation

HG Chain Design for HyperGlide+

HyperGlide+ dedicated chain delivers greater chain retention, improved shifting efficiency, and smoother transmission over rough terrain.

Benefits and features:

• Improved chain retention encourages more aggressive all-terrain riding and relieves chain-issue anxiety
• Smoother drivetrain transmission and enhanced shifting performance sharpens riders’ concentration and improves acceleration
• Better chain engagement cuts abrasion, reduces maintenance, and lengthens the lifespan of the chain

Revamped HG chain features an extended inner link plate that connects seamlessly with new chainring tooth shape for ultra-efficient drivetrain performance.

This design change reduces the vibrations normally caused by the inner and outer chain plates rolling onto the chainring, and provides better chain engagement, stronger retention, and smoother pedaling.

Features

• All-mountain crank set is tough and aggressive yet also lightweight
• Forged crank arms rigid whilst being incredibly strong and durable
• HollowTech II integrated bottom bracket design uses a wide bearing placement with a large axle diameter for increased stiffness, efficiency and added durability
• We recommend that the bottom bracket is initially installed by a bike shop to ensure perfect facing and fit
• Direct mount chain ring
• For use with 12-speed HG MTB chains only
• With a 51.8mm chain line for use in conjunction with 142 / 148mm O.L.D
