Contemplating a semi fat tire rim brake bike and curious what the max. (700c) tire size you can run if everything is optimized. I assume it would be the single bolt Racer M not the braze on version. I have a bike with 35 x 700c tires with mid reach brakes currently and doesn't appear to be room for anything much bigger. The bike was not really built for mid reach brakes (canti frame

Fork and frame would be custom if I decide to go this route.
