Yes: Don't do it. While you can probably make such an arrangement work on a 700c steel frame, the Swift, given it's short, stiff chainstays, won't compress to take up the slack, and aluminum is much less forgiving than steel in this regard. I.e., don't bend it too far.

If the axle is long enough, you could add spacers to move the locknuts out to 135 mm, but unless you're talking about a track/fixed gear hub, the axle is almost certainly not long enough.

Wheels Mfg. makes replacement axles, that's one option. The other is a new hub.

Sorry,
Jack
