I have a early model Dahon which does not brake reliably(OLD drum-and-belt system), and I want to fit it with caliper brakes(I have seen pictures of similar frames with calipers). If I have to replace the back wheel to do so, I'd rather replace the front as well(as it's corroding anyway). Here's the catch: the rear fork is approx 119 mm wide, while the front is 65. My LBS's supplier doesn't have ANY wheels with a OLD(which, if I read it right, is a length measurement) less than 100. So here's my question:

Can anyone point me to a place where I can buy said wheels, or a place where I might be able to get a new wheel built(using the existing hub for the front wheel) that con;t cost an arm and a freaking leg.

If neither can be done, I'm thinking I'll just put it back the way it was, and buy a new machine WITHOUT an archaic brake system.
