Just wondering if anyone has ever fitted their road crankset on a frame with BB92 standard? Saw this all-road frame but it had a BB92 standard for the BB which seemed a little odd, was wondering if anyone has done it before and any chainline issue?

Chainline issues aside - the axle of a road crank has a good chance of just physically being too short to fit.
I've never actually measured it down to the mm, but I believe my SRAM Red crank has an axle length of <90mm - it would not fit in a 92mm wide BB.
