Can I use a short reach brake fork on a frame designed for mid reach brakes? I'm willing to sacrifice a little tire clearance for weight and ride quality. 28s in front are fine and what I run now but am willing to limit myself to 25 if it would become necessary. It's hard to find new mid reach carbon forks that are a good value for a cheap bike, all the best deals are short reach. Discs becoming the standard only further limits the pool of all rim brake options.
Being as cheap as I am I'm even considering the possibility of adjusting the brake pad to the top of the slot in the existing caliper rather than installing a short reach one. I'm not certain it would work and thinking most likely not - there's only 2mm of overlap between the 39mm-49mm and 47mm-57mm range of the two standards.
