The ultimate long-lasting component system: CUES LINKGLIDE RD-U4000 9-speed rear derailleur from Shimano

LINKGLIDE consistently delivers smoother, more even pedaling while shifting that you can barely feel at your feet. LINKGLIDE's optimized shifting gate design that creates a smoother handoff between cogs to avoid the jumps that can impact shifting and pedaling smoothness. This design improvement is especially pronounced on outward shifts where pedaling shock is more noticeable due to the larger forces involved.

Drivetrain durability is essential for high torque e-bikes and daily riders who might ride in the same gear for months or years at a time. LINKGLIDE provides smooth and decisive shifting that lasts longer than ever before. LINKGLIDE's re-designed cassette teeth have a substantially thicker base and a unique chamfer that drastically improves wear resistance in high torque applications. This increase in cassette durability prolongs smooth driving performance and lengthens the amount of time before chain skips caused by wear start to happen.
