The Shimano CUES RD-U4000 LINKGLIDE 1 x 9-speed rear derailleur with SHADOW RD technology convinces with smooth and reliable shifting performance. This versatile 1 x 9-speed rear derailleur ensures undisturbed fun on the trails with smooth shifting and efficient pedaling. The flat design and chain stabilization offer ample safety reserves even on the roughest terrain. LINKGLIDE allows for smoother, smoother pedaling and barely perceptible shifting. The optimized design of the LINKGLIDE gears guarantees a smoother passage between the sprockets to avoid jumps that can compromise shifting and pedaling fluidity. This design improvement is especially noticeable when upshifting, as the downshift is more noticeable due to the larger forces. Drivetrain durability is critical for high-torque e-bikes and everyday riders who use the same gear for months or years. LINKGLIDE allows for smooth, fast shifting and lasts longer than ever. The redesigned LINKGLIDE cassette teeth have a much thicker base and a unique chamfer that greatly improves wear resistance in high-torque applications. This increase in cassette life extends smoothness and time before chain skipping occurs due to wear.
