Three different Schwalbe measurements on i44/45 rims, range 71-76mm...
Might have to just buy, measure and return if too big.
They going on a set of 100/135 wheels by any chance?
Possibly 135/170 in a Genesis Caribou, then later 110x20/150x12 in a frame that doesn't exist.
I haven't got any actual 29er frames.
