Any of the 12speed cranksets will work fine with 11speed chains and cassettes. Internal width of 12 and 11speed chains are the same.

Assuming your Trek has a 141 Boost frame the 52mm chainline will also be decent enough too.

If not and your Marlin has a standard 135mm quick release rear end then maybe an older 11speed Shimano crankset (M7000-1, M8000-1) with a 49mm chainline would suit your set up a little better, if you can source one.

 

Thanks! Yes, my bike has a standard 135mm QR.

Do you think a Deore 11 speed chain, derailleur, shifter and cassette would work?

 

No worries. 😎 Any 11speed chain will work fine, I've used a few namely Shimano, Sram and KMC and can't tell any difference.

I'd say if you want to keep things simple as long as the shifter and derailleur are the same brand and 11speed, the cassette is also 11speed then it's a fit and forget, no brainer job.

With you having a 135qr rear end I'd recomend one of the older cranksets with the 49ish mm (non Boost) chainline.

Example:-

SLX HOLLOWTECH II MTB Crankset 1x11-speed | SHIMANO BIKE-EU

Perfect for 1x11 MTB drivetrains, the SLX FC-M7000-11-1 crank uses a new 3D composite chainring for improved driving rigidity. It is available with 30, 32, and 34T chainrings.
