quick release question

I think you're describing a through-bolt hub. No, you can't use a regular quick release skewer, but there are special QR skewers for through-bolts that are a little easier to use than the two-nut design;

Can you take a picture of the existing axle/bolts and the fork ends (with the wheel removed)?

Thru-axles typically thread directly into the fork, and don't have nuts. Looking at pictures online, the SUB speed 30 doesn't have disc brakes, so it's highly unlikely that it would have a thru-axle. The exception would be is if Scott used some strange design to use a thru-axle hub with a standard fork.

I will post a pic tonight when I get home. However, it looks just like the top pic Diabloscott posted above. The silver one(minus the cam lever of course)

My bike does have disk brakes.

Disc brakes make it significantly more likely that you have a thru axle. To determine a replacement you need to measure a few things.

1) Diameter of the thru axle (common sizes are 15mm or 20mm diameter).
2) Distance between the nuts.

Any thru axle of the correct spacing and diameter should work.

It is possible that the OP has some kind of an anti-theft quick release.

The bolt should be about 1/8" in diameter.

If that is the case, then simply find a front hub quick release. Your local bike coop/recycler should have a pile of them. Or ask your local bike shop.

Lengths for the front are pretty standard.

Oh, good point. The hub he listed isn't a thru-bolt type.

And he said it looks like the regular QR skewer without the cam lever... that does sound a lot more like anti-theft skewers.

On another note - the reason thru-bolt became common on disc brake wheels is because of
1. Disc brake front wheel ejection, https://bikemagic.com/news/wheel-eje...igh-court.html and
2. Open skewer jamming in disc brake. Our Angle on the Trek Quick-Release Recall

So he'd be increasing some risk by putting on a QR skewer.

Thanks for the replies.

few say much details, so guessing 20 times has to happen
