Shimano's Most Durable Component System: CUES LINKGLIDE RD-U4020 9-Speed ​​Rear Derailleur

LINKGLIDE delivers smooth and balanced performance that you can barely feel when shifting and pedaling. LINKGLIDE’s optimized shift gate design ensures smoother shifting between gears, preventing jumps that can affect shifting and pedaling fluidity. This design improvement is particularly noticeable when shifting outwards, where pedaling shock is more pronounced.

Drivetrain durability is essential for high-torque e-bikes and daily riders who ride for months or years with the same gear. LINKGLIDE delivers longer-lasting and more precise gear shifts than ever before. LINKGLIDE’s redesigned gear teeth feature a significantly thicker base and a special tear-off edge that greatly increases wear resistance in high-torque applications. This increase in gear durability extends smooth ride performance and extends the time it takes for chain wear spikes to kick in.

SHIMANO STEPS – Taking E-Bikes to a New Level SHIMANO STEPS is the abbreviation for SHIMANO Total Electric Power System. The development of the component group was based on the idea of ​​perfect integration on the one hand and on the idea that an e-bike should still be a bicycle first and foremost. This should include comfortable and natural handling and riding behavior, as well as balanced power development when pedaling. The SHIMANO STEPS concept allows cyclists to combine nature experience and healthy exercise with exceptionally smooth motor support.

SHIMANO SHADOW RD The SHIMANO SHADOW RD is a mechanism rear derailleur designed for more aggressive riding. Its super low-profile design offers many advantages. Thanks to its low profile and single-stress construction, the rear derailleur does not hit the chain bearings under harsh riding conditions. The result is smooth, quiet performance.
