> Dura Ace rear hubs had chamfers on hubs lock nuts that when you aligned
with drop outs it spread them apart as you pulled wheel in allowing you to
insert a wheel with a say 2 to 3 mm more width than frame spacing. So that
is one way to solve a narrower frame spacing than the wheel spacing. Just
buy two of them and try that. A cheap answer. I used it and it worked
The problem with squeezing oversized axles (or clamping down on undersized axles) into a frame is that you put a stress on both the axle and the dropouts. Many times this sloppy technique results in broken axles, and sometimes broken dropouts. The failures don't happen immediately, but they will happen. Bruce Gordon http://www.bgcycles.com
