Mojo HD direct mount front mech and no Shimano 38/26 compatibility, why?

[Rick Draper]

Can anyone tell me why the Mojo HD with the direct mount front mech mount is not meant to be compatible with the Shimano 38/26 crank setup? I have a Shimano XTR race 40/28 setup but I am not man enough for it at the moment and would like a 26 granny ring so I can spin a bit more rather than having to grind, slog and grovel up everything!

I think I might have found the answer to this myself.

As the XTR 2x10 trail uses the same offset chainring pattern as the 3x10 I guess using the 2x10 front mech would cause the mech to foul the lower link? If that is the case I wonder if I could use a 2x10 trail chainset and a 3x10 mech limited to just the inner two rings without it fouling, as this works with the 3x10 chainset and the smaller granny ring.
