Will this Rival cage fit on Red RD

[TomP]

Hi all,
I came across this Rival medium RD cage on eBay. Do you know if it will fit a 10 speed Red RD? My Red has a short cage and I need a longer one. Thanks

Do you think you need a longer cage because you're trying to use a larger cassette?

On the 10 speed SRAM derailleurs the body of the derailleur is physically different from that of the short range to the mid range. Changing the derailleur cage from the short to mid will not change the clearance needed to run a larger cassette.

Thanks. Yes, I want to run a 32 cassette. I put in a longer B screw and can run a 30t cog. I'll just stay with that.

my shortcage sram red10 rear cleared a 32 just fine with a b limit adjustment. i could get a shortcage dura ace10 to clear a 32 as well with a b limit adjustment. on two different bikes so hangar length was not an issue.

Thanks! I'll try it again.

I think the wifli derailleurs are more than just a longer cage, the geometry is completely different.

The one on the bike is a wifli, below is a short cage.
