Thanks, Brenton. I just got and built up a newer 60cm Sam with canti's and was curious about the max size myself. I put on Schwalbe Marathon Greengaurds labelled at 50mm, about 47mm actual and they fit fine (mounted on Atlas and Cliffhanger rims - I tried on two sets of wheels with the same results). I actually have a bit more clearance than you show in your pics. I was wondering if the larger Cadezaros would fit with the knobs. Good to know.
