Sram Force compatibility

NateTheGreat

I know there have been tons of threads posted on many forums about this subject, but I couldn't find anything really that relates to me.
I am wanting to build a bike from a Ribble Sportive Racing frame because my old bike doesn't quite fit me, but the components on my old bike are pretty good (full 2011 10s Sram force groupset, Mavic Ksyrium Edition Spéciale wheels).

Now comes my problem... The Ribble frame has a PF30 BB and my bike has a threaded BB so my crank is a GXP crank and not a BB30/PF30 crank. But I can't find a 10s BB30/PF30 Sram Force crank used or new...

So I was wondering if I can use this setup no problem:
10s Shifters
11s Force Yaw FD
11s Force Crank
11s chain
10s cassette (11-28)
10s Force RD (short cage)

This site said it is possible for RED: http://velonews.competitor.com/2012/03/news/it-works-we-test-sram-red-backwards-compatibility_209270

Thanks for your help!

TLDR;
Will this setup work together? (10s stuff is from 2011 I think)
10s Force Shifters
11s Force Yaw FD
11s Force Crank
11s chain
10s cassette (11-28)
10s Force RD (short cage)

You can use everything you are suggesting but I would question the use of an 11 speed chain, it is narrower than 10 speed so will fit but I would stick to a 10 speed but others may have tried and tested knowledge.

Here is an old thread going over some of the details.

I had read somewhere that using an 11s chain helped with chain rub, but it seems that a 10s chain works too.
I also read that you usually want to keep the chain to the same speed as the cassette.

Thanks for your input!

Why not just use a BB30 to GXP adaptor and re-use all your existing groupset?

On one bike I have:-

10s Red Shifters
11s Force Yaw FD
11s Force Crank with 11 speed rings and sometimes 10 speed Q-rings
10s KMC chain
10s Shimano cassette (11-28)
10s Red RD (short cage)

All works perfectly. Think you need to use a 10 speed chain with a 10 speed cassette though. Doesn't matter whether it's 11 or 10 speed chain rings with that setup (I've used both) despite a quoted SRAM source somewhere on the web, they says it affects shifting. My front shift is perfect and trims just as it should.

But as above, I think your best option is a Praxis Works BB30-GXP BB adaptor and reuse what you have.

I looked at doing that and I guess spending 80euros on the adaptor is better then spending 300+ on a new crank and PF30 BB! Are the Praxis adaptors the best to get? Because the Sram ones I have heard are crap.
Though, I'll still have to get a new front mec since mine now is a band-on and the frame I want has a braze-on system.

Yes, a bit pricey but worth it. If you are going to install it yourself then you need two BB tools and a press-fit tool. Pay heed to the installation instructions as you mustn't crush the o-ring. The instructions are pretty simple you just need to follow them closely.

I was going to get my LBS to do it since I don't have the BB tools and they charge 14euros to put a BB in a frame. Cheaper then me buying the tools to do it myself and I support my LBS!

If the bearings are already in the frame, then the much cheaper adapters from wheels mfg at £25 work brilliantly, just slot them in and insert crankset.

Why are you swapping to a SRAM 11 speed crankset? You don't need it. Similarly you don't need a SRAM 11sp front or rear derailleur. You can save a lot of money and upgrade to full 11 speed using your existing front and rear derailleurs and crankset. SRAM are backwards compatible so your 10 speed derailleurs will work as 11 speed just by swapping your shifters to 11 speed. All you need buy is an 11 speed cassette, 11 speed shifters and the adapters for your existing crankset.

Unless your existing BB bearings are needing replacement, this type of adaptors (there are several manufacturers of similar ones) is all you need.
