Technologies

LINKGLIDE delivers seamless shifting and pedaling performance designed to last. The technology supports stress-free riding and ownership as bike types and riding styles evolve. Its 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. The 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 riding under high torque.

SHADOW RD+ reduces drivetrain noise and distraction. The rear derailleur stabilizer reduces chain slap and helps prevent chain drop. It is a simpler, lighter, and more efficient solution than a roller-type chain device.

STEPS stands for SHIMANO Total Electric Power System. The component group is developed around SHIMANO's idea of seamless integration, while also recognizing that an e-bike should still primarily be a bicycle. This includes comfortable, natural handling and riding behavior, as well as balanced power delivery while pedaling. The SHIMANO STEPS concept enables cyclists to combine experiencing nature and healthy exercise with exceptionally smooth motor assistance.
