I know from previous discussions that initially, cable-operated caliper brakes were not attached with centerbolts, but with clamps that went around the fork blades and seat stays. I dug back through and read posts about Bowden brakes, as well as similar items being used on many vintage French racing machines. I'm also familiar with the Resilion cantilever brakes that attached with clamps, rather than bosses, etc.
From another discussion (either here or another list), I understand that the bikes used for Keirin racing in Japan cannot be drilled for brakes. Allegedly, there is a modern caliper sold that fits these bikes via clamps, the way the vintage Bowden, etc., calipers did.
Does anyone have a source for these clamp-on brakes? Any pictures or a web link? I would think this would be the bee's knees for someone with a vintage, undrilled track machine they wanted to ride on the road.
