Cheers, yeah I think the size of tyre vs rim vs frame is ok, but I was worried about the axle interface. I’m not sure the surly through adapter and the halo one will work in their fork? If I just had to get the adapter I’d order it now, but the wheels are 100miles away :D
The midnight Special takes tyres up to 2,35 I believe. 30mm inner rim diameter is a bit wide for 2.25 tyres but shouldn't be a problem.
