LINKGLIDE delivers seamless shifting and pedaling performance designed to last. It supports easy riding and ownership across evolving bike types and riding styles. This exceptionally durable drivetrain is built to withstand persistent daily wear and provide lasting shifting and pedaling performance for multipurpose bikes and high-torque e-bikes. Its robustly engineered cassette shifts smoothly up and down the gears while significantly reducing drivetrain wear. The shifting gate design is optimized, and the robust cassette teeth resist damage when shifting and pedaling under high torque.

SHADOW RD – The SHIMANO SHADOW RD rear derailleur is intended for more aggressive riding. Its super-low-profile design offers several benefits. Because of its low profile and single-tension construction, the derailleur does not hit the chainstay in rough riding conditions. The result is smooth and quiet performance.

STEPS – Stands for SHIMANO Total Electric Power System. The component group is developed around SHIMANO’s idea of complete integration and the view that an e-bike should still primarily be a bicycle. This includes comfortable, natural handling and riding, as well as well-balanced power delivery while pedaling. The SHIMANO STEPS concept lets cyclists combine time in nature and healthy exercise with exceptionally smooth motor assistance.
