SRAM and Shimano 11 speed mixing

[rliu]

Hi I know this is another often re-tread topic, but as I got some very well discounted SRAM Force shifters and brake calipers last week from Planet X I am looking at the various component combinations and wanted to just re-confirm:

• SRAM shifters on a Shimano Chainset should be fine? I have a BB92 BB already with a second hand frame I recently bought (actually the same frame as a bike that was stolen last year)
• I should get SRAM front mech and rear mech
• I want to get SRAM cassette but a Shimano cassette is potentially also fine?
• I have a KMC 11 speed chain lying around which should be OK with either SRAM or Shimano cassette?

Thanks

The answer is they mix fine. Even 12 speed, but Shimano Deore works better than SX and NX

Chains, cassettes & chainrings are interchangeable so you can use any manufacturer (except Campagnolo), but you must match shifters and derailleurs by brand and speed.
Just beware that SRAM Force/Rival/Apex 11 speed shifters are 'exact actuation' and cannot be used with 11 speed NX/GX derailleurs which are 'X Actuation' with a slightly different pull ratio, but they can be used with the Rival/Apex 1x 11 speed derailleurs as well as the road equivalents.

Chain OK. Cassette interchangeable. Chainset agnostic. Brakes OK provided road calipers. As @Jenkins adds caveats to what you say in bullet 2.

Great, thanks for confirming on that everyone

How would a 2x 11 speed derailleur function on a 1x11 system?

@wheelsdownassup It would shift the chain from the smallest sprocket to the largest sprocket and back down again.
If this answer useless, define 'function'.
Chain likely to be shorter as 'large' ring will have fewer teeth (eg a 40 as opposed to a 50 in a compact).
