Because the QB came with quick-release hubs, the axles on those wheels are hollow and the axle probably only extends ~5mm past the locknuts, so adding 5mm of spacers on both sides to space the wheel out to 130mm would probably take up all remaining axle overhang, if you'd even be able to thread the locknuts on at all. Running an axle flush with the locknuts isn't ideal, but supposedly Sheldon did it on a fixed gear with vertical drop outs to provide a modicum of chain tensioning ability. If the intended bike has horizontal dropouts I think you'd just be setting yourself up for wheel alignment headaches.
Generally, if the axle is too short the answer is to replace with a longer one it and add spacers. I've never worked on a QB hub so I don't know if it's just a plain axle in there that can be replaced or if it has some type of proprietary shoulders for the cartridge bearings, which probably make finding an appropriate axle difficult or impossible. Cheaper bolt-on fixed gear hubs that we ubiquitous ~10 years ago generally came with long axles such that you could add spacers under the locknuts for just this situation and still have plenty of axle left to go through the dropouts and thread an axle nut onto. If it were me trying find a cheap solution to run a track hub on 130mm spaced bike, that's what I would look for. My favorite were sold under the Formula, IRO, Harris, and maybe Origin 8 brands. In the rear, chainline is the measurement from the center of the hub (measured between the locknut faces) to the centerline of the cog, so adding an equal number of spacers under the locknut on both sides of the wheel wouldn't change it. If you space the two sides unequally, you will change the chainline, but you will also then have to re-dish the wheel. This is a common technique for converting old multi-speed freewheel wheels to singlespeed or loctite fixed gear.

I'd rather use it in a 130mm spaced frame (but does that mean > chainline will be off?) > > -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
