I put mine in front of the fork, so it sticks straight up. Just because. (It really doesn’t matter.)

Newer closed cam skewers - at least Shimano - have been changed not to go past 90 deg angle to prevent this. Took me awhile to readjust the visual cue to how it should look.
While I do appreciate the actual braking from discs, there are some fundamental flaws in the engineering that frankly makes me embarrassed.

I always point them straight back mainly because they need to be somewhere and that is probably as good as any. Pointing back does reduce the chance of them hooking something when walking the bike.

The TT crowd says this is also more aero.

Iíd also add that generally you get about the right closed tension if you adjust the QR nut so that you are just feeling the onset of some tension when the lever is about straight out. Obviously it will vary, but that is a reasonable starting point.

FWIW, the illustration is NOT showing a QR on the drive side.

That said, it makes zero difference which side you run the QR lever in most cases. And it makes perfect sense to run the QR on the drive side if you have discs for the simple reason that you are less likely to get your dirty little fingers on the rotor when opening and closing the lever.

I tuck the QR lever behind the left fork leg front, and between the seat- and chainstay on the rear. Clean look and levers out of the way. I mounted my QR on the left on my disc-equipped MTB, but I ensured that there were no clearance issues. If there were, Iíd have no hesitation mounting the QR on the right, tradition be damned

The skewer should go in front of the fork. The lever can move further inboard so it is tighter. The fork leg also can get in the way if the lever is angled across the leg. These two picture illustrate the problem nicely. On the suspension fork, the lever can’t be closed in any position except vertical.





The idea that the lever is going to catch on something and open is a very old myth. In 40 years of riding (and 35 years of mountain biking) I’ve never caught anything on a quick release skewer. The chances of opening one through some kind of impact is infinitesimal small.

On all my bikes, I can rotate that lever about 30 degrees back so the tip is between the fender stays and the fork. With modern curved levers, I can see daylight between the fork and lever with the leer pushed to its stop.

My levers include early '00s Campy, slightly newer Ultegra and 105, cheap steel Shimano and QBP. All forks are traditional tapered steel, 531, Japanese Hi Ten and the like.

A thought I had looking at your vertical lever - what a temptation for kids! Mine would not even be noticed and the smaller ones would not be able to sum up the strength to open it with the fewer fingers that fit.

Does not apply to all OEM axle types. An aftermarket option can often change how the process goes, but that usually requires a hex head tool to preset the tension.

I don't think I've ever seen a qr skewer that could possibly interfere with a rotor. I just can't envision this. Did the lever come loose and turn over (rotate) 180 degrees?

If those are your qr skewers, I applaud your taste.

Donít think we ever thought about that at that moment. A flipped lever would arc outwards, making it less likely to snag the rotor.
But the mechanics were all there.
Once the q/r got loose enough, the lever did have enough range of motion to interfere with the rotor.
As If the wrinkled up rotor and tore up dropout would have left much doubt about how the event unfolded.

Yikes. I'm gonna check my skewers now. This is partly why I only use Shimano closed-cam skewers - seems like they are less likely to have any problems.

I wouldnít count on that. Look at the brands of bikes. Felt, Specialized, etc. Odds are good there were some Shimano q/r in there. But Shimano q/r made AFTER that date should be good, theyíre different. Iíll see if I can scrounge up a pair for comparison.
Edit:


Old vs current Shimano q/r
Top/left is an older Shimano q/r. Low/right is the recent design. Note how much lower the old lever dips.
Both levers in good, original condition.

Depending on the fork and the QR lever's shape, like was stated by Johnny HardKore, it depends. Just don't kick it.

Yup. Mine. Other than Campy, they are the only ones to own.

Okay, QR levers, fine. But what we really need to discuss is which way the Brilando clips are supposed to point...

This is probably the most logical post here. Especially true for mountain bike anyway, that can hook strong weeds etc, if in the forward arc.
