would this crankset be compatible?

campy 10-speed FD/RD
KMC 11-speed chain

currently campy 11-speed crankset 34/50
and works flawlessly

Mtb has a different chainline and wider q-factor. You'd probably be better off using an adventure crank if you need easier gearing. Fsa has them in 46/30.

If you had to pick an mtb crank it's probably better to go triple. Putting a larger chainring in the middle and removing the outer would be closer to road chainline.

White induetries sell road cranks in any size. You can get a 44/28 if you want. :)

ahhh, now i see mtb standard is 73, vs 68 for road

is that something that can be compensated with shims?

The spindle is of a fixed length. In the old days you could put a "road" square taper bottom bracket and use an mtb crank on.

You could still today but it's not very modern.

The spindle is only a little bit longer. The rest of the q-difference is in the arching of the crankarms.

The q-factor could be even desireable if you are very tall and prefer a wider stance.

In any case. Either use an older road triple crank, or look at fsa cranks. They have small bcd road cranks.

That way you won't run into fit issues later.
