The end of the crimp closest to the BB shell? I have 38c g-ones on mine, 18mm internal I think and theres a bit of space still but not a lot. I imagine the chain stays are all the same length for each size? Yours is a big one though
38c G one AR came up 42mm on my rims, about a mm or 2 clearance but rubbed when out of saddle/no room for any mud.
Think my rims are 24mm internal.
