SHIMANO CUES RD-U6020 11 SPEED REAR DEAILLEUR 45T MAX *LINKGLIDE ONLY*
Find new ways to enjoy trekking, trail riding, and daily flat-handlebar commuting with the SHIMANO CUES RD-U6020 rear derailleur.Engineered strictly for Shimano's high-durability Linkglide system, this premium 11-speed component provides incredibly slick, seamless gear transitions. The re-designed mechanical architecture drastically cuts down on the distinct drivetrain "jumps" and shifting shocks that occur under heavy pedalling loads, letting you maintain a fluid cadence.
Built using a low-profile SHIMANO SHADOW RD architecture, this derailleur sits remarkably flush against your bike frame.This clever geometry shields the derailleur body from common trail hazards like rocks, stray roots, and tight urban obstacles. It also features optimized spring tension to keep your chain firmly in place on bumpy terrain. Rigorously tested and reinforced to manage continuous high-torque output, it is officially E-Bike Rated to withstand the relentless pull of modern mid-drive motors.
Key Features
Linkglide Technology: Delivers smooth, robust shifting and a highly consistent pedalling feel that dramatically extends component wear life.
Shadow RD Low Profile: Streamlined geometry tucks the mechanism close to the frame to protect it from trail obstacles.
2x11-Speed Optimisation: Tailored to work flawlessly with double chainring setups to provide an ultra-wide gear range.
High Torque E-Bike Rated: Robust engineering certified to comfortably handle the power and high torque of electric bike motors.
Sleek Chain Stabilisation: Built with advanced spring tension to prevent excessive chain slap and drops on rough terrain.

Why This IS For You
✔️ High-Mileage Commuters: Built using hardened materials that resist the daily grind, perfect if you want to slash your ongoing maintenance costs.
✔️ E-Bike Trekking Riders: Safely manages the added stress of an electric motor assist without bending or degrading shift precision over time.
✔️ Wide-Range Double Lovers: The perfect upgrade if you prefer a 2x setup for tightly spaced gear steps alongside a massive 45T climbing gear.
✔️ Rough Route Explorers: Gives you the mechanical confidence to dive down unsealed gravel paths and singletrack without dropping your chain.
✔️ Set-And-Forget Bikers: Stays indexed and aligned exceptionally well, requiring fewer trips to the workshop for cable tension tuning.
Why This May NOT Be For You
❌ Linkglide Only Shifters: Operates on a unique cable pull ratio; it is completely incompatible with standard Shimano mountain or road shifters.
❌ Not For 1x Drivetrains: This specific 'U6020' variant is engineered for double front chainring setups; it will not work correctly on a dedicated 1x11 layout.
❌ Weight-Focused Racers: Constructed for heavy-duty commercial durability rather than the ultra-lightweight performance required for competitive racing.
BFC PRO TIP
Because the Linkglide system utilizes a significantly thicker cassette tooth profile, the RD-U6020 derailleur moves on a completely different geometric path compared to older Hyperglide models. If you are upgrading your bike, do not try to save a few dollars by reusing an old 11-speed shifter or a standard chain. To experience the legendary, skip-free shifting performance that Shimano promises, you must run this derailleur with a matching CUES 11-speed shifter, a Linkglide cassette, and a Linkglide-compatible chain!
