Anyone know first hand if it will work? My other option would be to use an XT rear mech.
Are you looking at 1x or 2x? Either way an 11-46 is too large to officially work. But if its 1x, then there is at least a chance since its 4t larger than the stated max.
For what its worth, a 30/34 bailout is the same as a 40/46 bailout in terms of gear inches. So a simple 46/30 crank mated to an 11-34 cassette will give you the same bailout gearing as a 40/46 while also giving tighter shift jumps and more overall gear range.
But hey, you do save a whopping 50g by going 1x, so if that is the driving motivation, it makes sense(2068g vs 2108g).
