i messured my tire clearance fom center axle to bottom fork crown, its exactly 290mm. if my calculation is correct with a 520rim+23tire+23tire i should end up with 566mm. this could end up by 7mm tire / fork clearance......and i am not shure if this would be enough, due the 520 is bead seat diameter......H15LHR, what the hight of your fork ?
