CUES RD-U4010 Short Cage Rear Derailleur - 9/10-Speed

Built for riders who demand clean, consistent shifting on compact wheel setups, the Shimano CUES RD-U4010 Short Cage Rear Derailleur delivers precision and reliability in a sleek, low-profile design. Whether you’re commuting through city streets or exploring mixed terrain, this derailleur keeps your drivetrain running quiet, tight, and smooth.

With its short cage configuration, the RD-U4010 offers excellent ground and tire clearance—perfect for small-wheel bikes and riders who value durability without sacrificing performance. Shimano Shadow RD technology ensures crisp shifting even in rough conditions, reducing the risk of damage from impacts and keeping the derailleur tucked neatly out of the way.

Smooth 11-tooth pulley wheels and refined chain management translate into responsive gear changes, while the simplified design without a cable adjustment barrel allows easier wheel removal and maintenance. Compatible exclusively with Shimano LINKGLIDE systems, it’s built to handle the demands of daily riders who want long-lasting, dependable shifting performance.
