Can you mix Shimano Shifters and Rear Der. with SRAM Cassette, chain and chainring?

For a 1x11 system:
I have an XTR shifter, XTR rear d, with a sram X01 cassette, sram xx1 chain, and sram front chain ring. I have this existing setup on a hardtail, works fine.

I am building an s-works enduro with the same setup. The folks at competitive cyclist said these parts don't play well together, and I am having second thoughts. Anyone else have this setup? any problems?

I currently have a couple bikes with almost that exact setup. 11s XX1 cassette and chain. XTR derailleur/shifter. And RF NW ring. No problems. Did they say why it won't work?

Should be fine, the 11 spd chain width is the same for SRAM and Shimano.

They just said "they don't play well together". But like you, I have had no problems on my current setup. Thanks for confirming I'm not alone in this.

Like you said - it works fine. There's quite a bit of mixing and matching of drivetrain components. CC is probably just trying to sell you some parts.

Sram and Shimano don't advise running their systems with other manufacturers components which is likely why competitive cyclist is pushing this.

There may also be compatibility issues with the 12 speed stuff.

My xt8020 4 pot caliper died, so I grabbed a new 8120 as it was cheaper. It doesn’t seem to be compatible - can anyone confirm? The lever doesn’t seem to push enough fluid.

My understanding is Shimano enlarged the routing orifices on the 7120/8120/9120 caliper assemblies and modified the lever assembly to help the Shimano mineral oil flow easier - that is not be as restrictive as in earlier calipers. This was especially evident in very cold temperatures.

Now I don't know if this has anything to do with your issue, but Shimano did do some redesigning internally.

Yeah, the caliper / hose banjo bolt and flow is massively different. I suspect the new lever pushes more fluid. It would explain them being backwards compatible (new lever, old caliper) but not the other way.

Bad bleed. Try again

So you’ve run this successfully? It’s had a fully bleed, and it’s behaving differently to other set ups.

All mineral oil Shimano lever and calipers are cross compatible, this hasn't changed with the new calipers.

There is some incompatibility across the line actually, but it's usually in the form of "doesn't push enough fluid". I've had issues bleeding Saint calipers to XTR levers and similar.

That said you can usually use a thinner bleed block and get them to work well albeit with sightly less pad spacing.
