I'm 99.9% sure the answer is no, but are there any problems with running a Shimano 11-speed mech with a SRAM 11-speed 10-42 cassette? As far as I'm aware the only difference is the smallest cog has one less tooth, which the mech won't care about, right?
Works just fine.
Running it on both bikes, all good.
Can I ask a related question?
I'm currently running a 1x10 Shimano SLX rear mech and shifter combo with a Hope T-Rex 40t expander. I'm thinking about moving to 1x11 in a desperate attempt to get a slightly easier gear for some of the big draggy climbs.
Will I need a new rear mech or will my existing one handle a 42t rear cog and the extra gear?

Beagleboy - new mech, cassette, chain and shifter.

Smaller chainring?
Aaah, forgot about the narrower chain as well! When I specc'd the bike I thought I was being brilliantly cheeky in getting a 30t front ring and an 'upgraded' 40t cog on the rear cassette. Being new to this sort of setup, I thought I'd be able to spin up anything with that. 😛
Now I realise I'm either going to have to buy my way out of trouble by getting easier gears, or suddenly lose about 4 stone and get fit, something that I've consistently failed to do over nearly 30 yrs of mountain biking!
Cheers for the info!

XXTR for the win. Or at least it was, until I fittted a Hope cassette.
10 speed chain works with 11 speed cassette and mech
11 speed mech works with 10 speed cassette and shifter. In fact, it works better than a 10 speed mech on 40t+ expanders.
The above is Shimano-based experience - XT M780 and XT M8000 stuff, YMMV. I hate SRAM gears - can't get on with them, don't care about the range or 10t cog, hate the look and feel etc.
