OneUp RAD Derailleur Cage

The OneUp RAD Cage optimizes shifting performance when using an 11-40/42T cassette on your 1x10 drivetrain. Essentially, the OneUp RAD cage is a replacement outer cage for 10-speed Shimano GS (mid-cage) clutch rear derailleurs that repositions the upper pulley to allow the derailleur to properly shift into a 42T extended range cog.

OneUp RAD Derailleur Cage Features

  • Dramatically improves shifting performance for Shimano GS (medium cage) Shadow+ clutch rear derailleurs
  • 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 - watch the installation video by clicking the Video tab above
  • Patent Pending
Specifications
Material 7075-T6 Aluminum
Weight 26g
Compatibility Shimano GS (medium cage) Shadow+ 10spd clutch rear derailleurs*
  • Deore (RD-M615 GS)
  • SLX (RD-M675 GS)
  • XT (RD-M786 GS)
  • XTR (RD-M985/RD-M986 GS)
  • Saint/Zee (RD-M820/RD-M640)**

*SGS models of the derailleurs above can be converted to use a RAD cage. This requires the purchase of a GS inner plate. The Shimano part numbers are - Y5XC09000 (XTR), Y5XC09100 (XT, SLX) or Y50H09000 (Deore). Any of these three part numbers are functionally interchangeable, however there may be material or small aesthetic differences.

**Saint (RD-M820) and Zee (RD-M640) use the XT spring mounting hole on the RAD cage.

Must Have Add On for Shimano Oneup
This is a must have for shimano rear derailluer setup. This allows the Oneup to perform its best with shimano gear.Cage looks cool in annodized colors. I got green which looks cool against my GT Force Carbon.

Shifts Smooth
I have this on my XT deraileur and wolfetooth 42T cog. It shifts super smooth and i never dropped or skipped a gear. Easy to install and set-up (for me), lightweight, and looks nice. If you have problems with your current deraileur even when running a longer b-screw, get this product. Me personally, if you run a 40/42t cog, id drop the money on this product. Id rather spend a little money on a product that will give me the best experience on the trails and not hinder my time riding. I highly recommend this to 1x10 converts with a 40/42t rear cog.

Brought back the crispness
I recently upgraded my xt drivetrain to a 1x10. I battled hesitation in shifting through th high gears regardless which gear i removed, the 15t or 17t. So i got the 16t from one up and experienced the same hesitation. I've been riding an xt drivetrain for years so i am spoiled with crisp on point shifting. So i started to doubt my upgrade until i installed the RAD CAGE. Super easy 15 min install that brought my shifting back to o.g. status. This is the most important piece of the xt conversion because u dont have to max out the B tension screw, thus keeping the guide pulling closer to the high part of the cassette while still allowing clearance for the 40/42t. It is a must have if u r converting ur xt drivetrain.

It works
Put this on a Deore to use with an 11-42T 10 speed cassette, works exactly as advertised. The installation video was pretty helpful too.

Sexy looking
The best upgrade so far on my bike. Made my shifting smoother going to 42t cog. Looks cool too and I have more space not to hit rocks .

Shifts are definately improved
I changed from a Zee short cage that never shifted great on my 1x10. Now the shifts are direct and chain slack is not an issue

Easy to install, sturdy and effective
Installed it on shimano m615 derailleur. One up install video was really helpful, however it didn't mention needing a screw extractor to remove the press fit clutch pivot/upper pulley bolt. Otherwise the cage is really strong and installs easily. Newly positioned upper pulley makes shifting smooth again on an extended range cassette.

HI I would like to knbow if this plate is compatible with Shimano RD-M9000 long cage derailleur
Victor on Sep 13, 2016
BEST ANSWER: I'm not completely certain. I think I used the Rad cage for the medium cage derailleur and the Radr might be for the long cage. This should be available on the Oneup component website.
