Hello,

I´m looking a new bike mounted full in Sram Rival 22 (11 speed) with 50/34 crankset and 11-32 cassette, but i want to do it more versatile and i want to know if this combination between sram rival 22 and sram GX (2x11 mountain group) would work:

-Crankset: Sram GX 24/36
-Front Derailleur: Sram GX
-Shifters: Sram Rival 22
-Rear Derailleur: Sram Rival 22

Any suggestions are welcome
The bike is a planetx london road,
Thanks

The front derailleur will not work very well.  Mountain and road front derailleurs/shifters use different cable pulls.  So while it will shift, it will be extremely difficult to adjust to get it to work.  I would expect a Rival front derailleur to work just fine, even with the smaller chainrings of the mtb crank.

No. The crankset/chain rings won't play nice. Best bet is to wait it out for the FSA 46/30 crankset.

The sram Gx 2x11 speed front derailleur is x-actuation, i don´t look, but the Gx 2x10 front derailleur is exact actuation, the same of Rival 22 groupset, so would it work fine with rival 22 shifters and Gx crankset?

Other thing is the chainline, i don´t know if the mountain crankset/front derailleur and the road rear derailleur will work.

Thanks for the replies

The London Road has a 135mm rear, so the chainline would be the same as on a mountain bike.  So there won't be a chainline issue.

SRAM 10-speed mountain and road shifters have the same actuation and can be used interchangeably. Personally, I'm running a SRAM Force front derailleur with an X7 rear derailleur on a 2x10 system and it works great.  My understanding is that SRAM 11-speed does not play interchangeably.

Yeah that sounds familiar. 10 was okay, but not 11.

Thanks.
So can i use a front derailleur and crankset of 2x10 mountain system on a 2x11 road system?. The actuation is the same.
Are there any difference in cranks and derailleur for 10 or 11 speed?.

As long as the front derailleur works with your crankset and shifter, it can be combined with any rear driver train you want.
10 Speed chain rings should be fine with an 11 speed chain, it's the outside that got narrower.

According to Lennard Zin, you can use a 10 speed (road or mtb) SRAM derailleur with an 11 speed road shifter and and casette.

Alternatively, you may also want to consider running a Shimano CS-M8000 11-46 cassette or SunRace 11-46 cassette with a Rival1 long cage derailleur and just a single chainring if you want to avoid the hassle of making it work with a double. I love my setup and it works beautifully:

I have heard that Exact Actuation 10 speed rear derailleurs and Exact Actuation 11 speed front shifters "should" work together, but months of internet searches had never found a single actual account of anyone who had actually tried it and found it to work.

Today I took the SRAM Rival 22 11 speed rear derailleur off of my All City Cosmic Stallion and replaced it with a GX 10 speed long cage rear derailleur. It worked fine on the work stand, so I took it out for a short ride (in the rain). Worked fine. No different than the good shifting with the Rival RD.

I’ve done the reverse for a while now and it works perfectly; Rival 1 Long Cage with old Force 10-speed shifter and a SunRace CSMX3 11-46 cassette and it works perfectly. It shifts much better than with the GX 2x10 long cage that I replaced it with, in fact, which would be better for a 2x10 setup (more chain takeup) than the 1x10, where the 1X derailleurs shine (better upper jockey wheel alignment for handling really wide range cassettes).
