I've got a C-dale CAD3 roadbike which I'd like to switch to cantilever brakes so that I could use 'cross tires in the winter....on the cheap. I've got a set of X-tires wedged in there right now, but I've had to space the rear wheel down about 3/32. Firstly the tires still rub a bit and secondly, I don't feel safe about this setup at all. Although my fork is steel, I expect that buying a cheap steel fork would be the best bet for getting canti's up front. For the rear, I'd need to have the current brake bridge moved up some for clearance and brake bosses welded on. The questions are: Has anyone heard of this being done before? Anyone know of someone in the Southeast Michigan area that might be able to handle something like this? TIA -Andy B.
