The RAD cage is a replacement outer cage for Shimano GS (medium cage) clutch rear derailleurs, that dramatically improves shifting performance of any extended range Shimano 10x drivetrain.


RAD Design

The key feature of the OneUp RAD (Radial Appositioned Derailleur) cage is that we’ve moved the upper pulley wheel rearward of the cage pivot to optimize the derailleur for larger sprockets. Now as the derailleur moves into larger sprockets the top pulley wheel automatically moves away to adjust the chain gap, no longer relying on just B-Screw.

The RAD cage is a 1x10 11-40/42 specific product only for Med cage derailleurs .  Long cage (SGS) derailleurs are only needed for 2x drivetrains.  Shorter derailleurs are preferred for 1x10 systems as they’re lower profile so less vulnerable to damage on the trail and they allow you to run a shorter chain which improves chain retention.
