One Up Components' original 42T adapter sprocket signaled the beginning of the wide range 1x10 drivetrain movement, allowing riders to achieve close to the same gearing as a 1x11 set up, at a fraction of the cost. Now they've taken things a step further, with the introduction of a replacement outer cage for Shimano derailleurs that's designed to help improve the shifting performance over the whole cassette.The press release from OneUp Components about the Rad Cage is found below. - Mike Kazimer
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. Combined with our 40/42T and 16T adapter sprockets it is the complete, no compromise Shimano 1X10 solution.
RAD Benefits - Dramatically improves shifting performance for Shimano derailleurs*
- Tuning your derailleur to achieve perfect shifting with an 11-42 is now much easier
- Requires stock B-Screw length and adjustment (No more removing washers or reversing B-Screws)
- Improves chain wrap and extends cassette life
- Installs in under 15 minutes – check out the

*Compatible with all Shimano GS (medium cage) Shadow+ clutch rear derailleurs
Typically stock Shimano derailleurs don’t perform as well as Sram offerings when paired with wide range 11-42 cassettes. This is due to derailleur architecture. The extra B-screw needed to clear the 42T means the upper pulley is further from the cogs in the lower end of the cassette. Shifting therefore can be slower and less responsive here.
RAD DesignThe key feature of the OneUp RAD (Radial Appositioned Derailleur) cage is that the upper pulley wheel has been moved rearward of the cage pivot to optimize the derailleur for larger sprockets. 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 B-Screw tension needed for an 11-40 or 11-42 cassette with RAD cage is about the same as is required when using a stock Shimano derailleur and 11-36.
Additionally the top pulley now sits above the cage pivot closer to the cassette, when in the lower end of the cassette (11T,13T,16T) resulting in much crisper shifting and more chain wrap.

OneUp Components - Work less ride more.
i have a job thanks, plus i've been planning on mucking around with the link piece when my 9 speed wears out next. hopefully slx 1x11 will be around by then so i won't have to bother my arse.
Offsetting the guide pulley as the One-Up cage does has two benefits. The first is, the guide pulley will run closer to the smaller sprockets, improving the shifting. The second benefit is that it allows the pulley to run farther forward, more under the larger sprockets than behind them, which will reduce wear due to the increased chain wrap. Your solution of extending the link between the derailluer and the hanger will not solve the problems that this does. Your solution would not only make the shifting worse, it would move the derailluer even closer to the ground making it more susceptible to damage. Also, continuing to claim that this piece costs the same as an XT derailluer when it is common knowledge that it cost less than half that, is not helping your argument.
tobiusmaximum isn't claiming Shimano is the only company that does it, just that it was the first company he personally was aware of doing it. It's something Shimano has been doing since long before anybody ever even heard of Sram. Frankly, there's not a major component manufacturer that HASN'T done it.
At the end of the day I'd like to see 1up making full drive trains just to increase competition and innovation.
The RAD cage should perform well with an 11-36 cassette. You'll need to change the B-tension when you add the 42T though.
This kind of stuff is surely messing with their estimate profits.
But as of now the shift quality has definitely been a compromise, making these mods no real replacement for the full 1x11 package. Hopefully this cage will fix that.
I'd love some one to confirm this for me?
God dam it I new I should of gone xtr in the first place
1) Shifting is back to stock 11-36 Shimano XT performance. Nice and crisp.
2) I disliked the performance with just the 42t and the stock XT derailleur. Enough so that I was going to remove it.
3) Chain wrap is improved enough to make the 11t useable again when really pushing it over bumpy terrain.
I have to say, this is a great option. I detest front derailleurs, but needed more range than 1x11-36 and did not want to have to replace the $300 X01 cassette and $250 X01 derailleur as a maintenance item. So for $150 (RAD cage, 42t, 16t and shipping) I now have a reliable, useable setup, with enough range for me. Good times...

Just ordered one for my General Lee.
