RAD Cage
$49.00 CAD
Dramatically improves shifting performance of any extended range Shimano GS 1x10 drivetrain.
The RAD cage is a replacement outer cage for Shimano Medium cage (GS) clutch rear derailleurs. Specifically designed for perfect shifting of any extended range 11-42T cassettes.
For short (SS) or long cage (SGS) Shimano clutch derailleurs check out the OneUp RADr cage.
- Vital MTB 4.5 review (Outstanding)
- Dramatically improves shifting performance for Shimano GS (medium cage) Shadow+ clutch rear derailleurs
- Chain Wrap (cassette wear) and Free Chain Length (shift performance) corrected to stock Shimano spec - See chart
- Tuning your derailleur to achieve perfect shifting with an 11-42 is now much easier
- Requires Stock B-Screw adjustment (No more removing washers or reversing B-Screws)
- Improves chain wrap and extends cassette life
- Installs in under 15 minutes – checkout the install video for full details
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.
