Hello
Just subscribed to Singletrack.
I have a NORCO Fluid 7.2 which had as standard a DEORE setup as follows:-
Cassette Shimano HG62, 10-speed, 11-36t
Chain SRAM PC 1031
Cranks Shimano Deore 22/30/40t
A few years back I got all excited about 1 x 10 so changed the crank to a RACEFACE Ride 1 x 10.
I'm now excited about the new Shimano SLX 1 x 12 and wanted to know if it would fit?
If not perhaps the older 1 x 11 SLX might ?
Any help would be appreciated

I think SLX 1x12 can fit most bikes but you have a few considerations:
Firstly, can you get a shimano 12 speed compatible chainring to fit on that crank (unless you will change out h thy at crank for a shimano one) - the chains for shimano 12 speed have a different inside width to 10/11 speed ones.
Secondly, can you get a microspline freehub for your rear hub? Shimano 12 speed has a different freehub standard to HG which is what you have.
If the answer to the above is no then you need to have a think about the ivarall cost can benefit.
Shimano 11 speed is an easier option for you as the 11 speed cassette will fit on your existing freehub I’d think and your existing chainring may work - if not it should be easy to get an 11 speed NW ride that’ll work fine.
I think it's the outer, not inner, width of 9-12 speed chains that has changed.
1x11 will be easier and cheaper - i.e. you won't need to change the freehub or rear wheel if a freehub isn't available.
For 11 speed 11-46t Shimano will be more than adequate or if you really want a bigger gear then go for a sunrace 11-50t.
Don’t rule out improving your 10 speed set up. The HG500 11-42 cassette is great, as is the (newer) 42 tooth compatible Deore 10 speed mech (although you can use any Shimano mtb 11 speed mech with your current 10 speed shifter). I did this to build a second bike up as cheaply as possible, and it performs very well indeed. Prefer it to my XTR 11 speed setup, fewer double and triple shifts required.
You’d only need to buy… cassette, mech, chainring and chain.
If you have the 1x Raceface cranks then why not just swap the rear cassette for an 11-42t 10 speed?
Your current rear mech might also be OK with that set up too.
Will need a new mech.
