Left crank compatibility between Shimano Hollowtech Road/MTB

[Fatal Swan]

I started using a smart turbo trainer lately and I use the mountain bike on it (for various reasons). I quite fancy fitting a stages Power meter as the left crank. The question is: If I use a Shimano MTB hollowtech II chainset (M770, etc) will the axle fit a left crank from the Shimano road range (i.e. one with a Stages power meter fitted)? Normally I'd just try it myself but the MTB currently has an M970 XTR chainset which has the special fitting on the left crank.

Cheers

Anyone help with this one?

Re:

I think you will be able to do as you plan, though most road cranks seem to be 172.5, so finding a match might not be that simple.

I think you'd be fine using an m960 chainset too, it was only m970 that had the different interface (why, it's a lovely crankset, and with that interface, engineered limited lifespan).
