Actually, going from 630 to 590 is not such a big deal. I did that on my Fothergill; the old GB brake calipers have slots a full 2 cm long, and it worked. But not all 26" wheels are 590 mm; most are in fact 559 mm. Going from 630 mm to 559 is a very big deal. I've done that, too; with drum brakes. And shorter crank arms.
