Trek says you cannot run 650b due to the frames low BB but I measured my 650b wheels with 2.1 tires against the stock 700c wheels with a maxxis rambler 40c tire and it's pretty much the same height.
The checkpoint will clear even a 2.2 tire I tried with a Continental X-King 27,5 x 2.2 and it fits even with the sliding dropout as far forward as it'll go. I saw someone on instagram running 650b wheels with bontrager XR2 with 27,5x2.2 tires on the carbon Checkpoint. But tires vary a lot from brand to brand, the Kenda Small Block Eight Pro i'm currently using is actually wider then the x-king 2.2 I tried before, the tire comes real close to chainstays so you wont have much mud clearence. With that said for the local dry rocky terrain more tire volume was excelent I'm a lot faster now and I dont worry about rim strikes as much.
