Hi all,

I'm new :D . I have the pleasure of now owning Ian stannard s dogma Brit champ bike.... Amazing on 11 speed dura ace di2.

All due to an insurance pay out as I wrote off my last bike.

My question, I have a training bike on sram red 10 speed. Rear and front derailleur are 10 speed and relatively new - can I use the new sram red 11 speed shifters with these 2 items? Thanks

Rear derailleur will work perfectly (I have both a red 22 and a 10s aeroglide running with red 22 shifters, and cannot tell any difference whatsoever between them other than a 22 painted on the red 22 derailleur). Front derailleur will most likely work: the 11s cage shape is slightly different, and works better in my experience: Probably worth updating it to either the force or red 22 version.

I ran the 10 speed Yaw FD with 11 speed campy, no issues. I plan on running it on an 11 speed sram TT bike, will report back on those results.

So you guys are saying 10 speed rear derailleurs work with 11 speed shifters? Do you just have an extra click at the top or bottom of the cassette?

You'd need to use 11sp cassettes and chain, and it'd make an 11sp system. The indexing is in the shifter.

So you are saying that both Red 10s and 11s RD have the same geometry?

I'm actually saying any rear derailleur with exact actuation will work with a red 22 shifter.

The specs for the shifters actually say as much: "COMPATIBILITY SRAM RED 22 & Force 22 Yaw™ Front Derailleurs, Exact Actuation™ Rear Derailleurs"

Cage shape. There's a ridge that's more pronounced in the 11s yaw derailleurs - I assume it helps to move the chain better, as the 11s outer width is slightly narrower. Its hard to see without actually holding them side by side, but its definitely different. I'd planned to test width with a micrometer, but the eyeball test showed they were different, so I didn't bother.

I tried using the 10 spd one on my second bike, but the shifting wasn't quite up to snuff. Replaced it with the 11s one, and fiddled a bit, and got adequate shifting. That being said, the second bike uses 36/52 rings, and has always been a bit more finicky than my other bike running a standard 39/53.
