Who makes modern skewers for 126mm dropouts?
 

Do any of the "usual suspects" (i.e., Salsa, Mavic, DT Swiss...or, heck, Shimano or Campy) make 126mm versions of their current, modern skewers?

Do you mean a complete hubset, or just the QR skewer?? If you just need a QR skewer I wonder if you can't just take a 130mm one and screw it down a few more revolutions. If not, I imagine there are plenty of used ones on ebay. If you want a complete rear hubset at 126mm your best bet is NOS also on ebay (that is what I did for my new 126mm rear wheel).

I've got a fork with an 80mm dropout, so I've been there. I have a die and cut new threads as far as I need to go, then trim the end of the skewer with a Dremel.

sasin, sachs mallard. not sure they meet the definition of modern.

Depending on the width of the dropouts a 130mm skewer might have enough threads to work. Failing that, you could get a machine shop to cut the threads farther down on a 130 mm skewer.

At least some of the new ones will work on a 126 with some extra threads sticking out. You can hacksaw them if you want.

edit: I put these on an olde Record hub with 126 spacing.

Just the QR skewer.
Hadn't even occurred to me to try a 130mm but jeez, that's only 2mm longer per side so I'll bet that oughtta work. Then again, clearly I suck at math almost as much as I do at bike wrenching, so all bets are off...

careful though, modern skewers are designed w/ vertical dropouts and lawyer tabs in mind, so they often have less clamping force.

if you have an older bike with horizonal dropouts and no lawyer tabs, you might not be able to clamp a modern qr tight enough for security / safety.

just use a regular ole skewer. should have enough threads for ya.

Completely untrue - plenty tight. You also have gravity helping to keep the axles in the dropouts.

Unless you're running them with an older bike which has horizontal dropouts. And if the OP is looking at 126mm options, that might very well be the case. There have been plenty of reports of people with issues trying to clamp modern , exposed cam type skewers in horizontal dropouts. Shimano or Campy should work though.

So not completely untrue...

use the cheaper shimano skewers, at least I know my 105 and ultegra skewers have enough thread and an open ended nut to allow you to screw them into 126mm drop outs.

If we're talking about drop outs, then I know for a FACT that it can be done with a freehub. A fixed gear is another issue.

If we're talking about FORK ENDS (which are what rear facing horizontal dropouts are called) I dunno if I'd risk it.
