OneUp RADr Derailleur Cage

The 2nd Generation of RAD cage. The OneUp RADr Cage was designed for Saint and Zee rear derailleurs but also works just fine with any other Shimano Shadow+(clutch) rear derailleur. The OneUp RADr Cage optimizes shifting performance when using an 11-40/42T cassette on your 1x10 drivetrain. Essentially, the OneUp RADr cage is a replacement front and rear cage for Shimano clutch rear derailleurs that repositions the upper pulley to allow the derailleur to properly shift into a 42T extended range cog.

OneUp RADr Derailleur Cage Features

  • Cage length is between GS and SS cages to offer the shortest 42T compatible cage possible
  • Dramatically improves shifting performance for Shimano 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
  • Provides the lowest possible profile to prevent unwanted cage strikes
  • Patent pending
  • Installs in under 15 minutes - watch the installation video by clicking the Video tab above

Works Great!!
I have installed 2 of these on my bikes, one with a Zee derailleur, one with a Deore derailleur. Both work great with a 42t cog. I have the B-screw in the stock position and they both cleared the big cog no problem. Both shift great. Highly recommended.

PROS: Easy To Install, Attractive Design, Lightweight

Revives shifting
The RADr cage was installed on a deore derailleur. This cage is in my opinion well worth the investment in a 1x10 setup, the shifting quality is improved drastically!

probably the best 10 spd upgrade you can do
I read reviews on this and had to try it. it was the best upgrade to my drive train that I could have made. pair this with the cassette expander cog kit from oneup and you have a winning combination! easy to install and set up.

PROS: Lightweight, great design, spot on shifting

CONS: none

BEST USES: Single Track, Cross Country, enduro, all mountain

Fixed by 11-42 cassette issues on my 1x10
This cage is great! I subbed in a 42t ring to my 10 speed 11-36 cassette and had the b limit screw maxed which was causing slow and intolerable, skipping shifting. This case fixed it all! Easy install and my shifting is back to normal.

Good Engineering
The engineering of this product was well thought out and works flawlessly. I was pleasantly surprised. The videos are extremely useful for install, without those I would have been a little overwhelmed.

Really sexy but unnecessary
Bought this for my wife. It's fairly easy to install and the video's online make it pretty straight forward but you'd have to be comfortable with biking stuff in the first place. It's a nice little piece to add a little sexiness to a bike but is totally unnecessary. I installed the OneUp expander cog first and the Zee derailleur still worked really well. I then installed this derailleur cage and it worked about the same. The only major benefit is that it is slightly longer than the Zee cage so it helps to solve any problems with the chain being to short for the transition from 36-42. In the end it was worth it for the marginal gain in performance and the added attractiveness.

PROS: Durable, Attractive Design

CONS: Limited Compatibility

BEST USES: Upgrade, Mountain Biking

Is this cage Compatible with Xtr RD-M9000 derailleur?
Victor on Sep 13, 2016
BEST ANSWER: Not sure why you would need the RADr Cage on an XTR RD-M9000 rear derailleur. This derailleur is designed to handle larger 11-42t cassettes without any upgrades or modifications. The XTR RD-M9000 rear derailleur is however NOT listed on OneUp's website for compatibility with the RADr Cage.
