Bring wireless electronic precision to your everyday and adventure riding. The Shimano CUES Di2 RD-U8050-SGS delivers smooth, reliable 1x11 or 1x10-speed LINKGLIDE shifting with a long-cage design that handles cassettes all the way to 50T — perfect for commuters, tourers and trail riders who want durable, low-maintenance performance.

Highlights

• Wireless Di2 electronic shifting: Bluetooth LE and ANT connectivity for cable-free operation with compatible CUES Di2 shifters.
• Long-cage SGS design: Accommodates LINKGLIDE cassettes up to 50T for a wide, versatile gear range on climbs and flats.
• LINKGLIDE durability: Engineered for resilience under the loads of commuting, touring and e-bike use — longer chain and sprocket life than conventional drivetrains.
• Function button and LED indicator: Built into the derailleur body for convenient system control and status at a glance.
• SHIMANO SHADOW RD: Low-profile design reduces snag risk and keeps the derailleur stable on rough terrain.
• E-TUBE PROJECT Cyclist app: Tune shift timing, customise function button behaviour and monitor system status from your smartphone.
• SD300 port: Single wired connection port for battery and system integration when wired operation is preferred.

LINKGLIDE drivetrain

Shimano CUES is built around LINKGLIDE technology — a drivetrain standard designed for high-load, high-mileage use. Ramped chain and sprocket profiles deliver consistently smooth shifts even under pedalling load, while the increased tooth and chain plate contact area means your drivetrain lasts longer between replacements. It's the right choice for riders who put real kilometres on their bikes.

Di2 electronic shifting

The RD-U8050-SGS is part of Shimano's CUES Di2 system, offering wireless or wired electronic shifting with precise, repeatable actuation. The derailleur supports both 1x11-speed and 1x10-speed configurations, and integrates with Shimano's E-TUBE ecosystem for firmware updates and personalised setup via the E-TUBE PROJECT Cyclist app.

Compatibility & fit

Designed for Shimano CUES Di2 1x11-speed and 1x10-speed groupsets using LINKGLIDE cassettes and chains. Supports a maximum sprocket of 50T and minimum of 11T, with a total chain wrap capacity of 39T. Compatible with HG freehub bodies. Wireless shifting requires a compatible CUES Di2 shifter (e.g. SW-EN605). Note: compatible with e-bike systems or the Shimano FH-U6060 hub. Confirm full system compatibility before purchasing.
