This as a result of quick release levers getting caught in disc brake assemblies, or so this article says:

[Edit] Ah, here's the recall notice:

So people are not smart enough to put the lever on the opposite side from the disk? Darwin award for them all? What am I missing here?

To create another new / improved / updated version of......lawyer tabs for discs to protect us.....not.....

Front [at least] will be thru-axle on all production bikes by the 2016 models, I predict. Trek will be the leader in this move, just a guess.


Folks will crash and burn from stupidity no matter what.

...which is typically the low-end, all-steel stuff or vintage gear that's not likely to find it's way onto a disk-brake bike. I don't have a skewer on any of my disk-brake bikes that can open past 180 degrees and most don't even open that far. Shame on Trek for letting this get through their testing process.

I read it covered almost a million bikes from $500-1700.00 or similar. That they use that skewer on 1700.00 bike and 500.00 ones...

If the skewer opens past 180 degrees, wouldn't it also be at risk of getting caught in the spokes?

...as the spokes are generally much farther away and the angle of spoke would tend to push the skewer handle out, rather than trap it.

What it really tells me is people in general are idiots and just don't understand how a QR works. If you don't know how the equipment is used, don't use it until you learn it intimately.

Common sense should tell the user to put the lever on the opposite side of the disk. If it doesn't they need to buy shoes and turn to running as a exercise outlet.

That's the rarest commodity of all. If it were more common, we would have 1/10th of the lawyers we have now.

But they are not required:

What IS required: (from http://www.cpsc.gov/en/Business--Manufacturing/Business-Education/Business-Guidance/Bicycle-Requirements/):


What requirements must wheel hubs meet?


All bicycles (other than sidewalk bicycles) must meet the following requirements:

(1) Each wheel must have a positive locking device that fastens it to the frame. Use the manufacturer’s recommended torque to tighten threaded locking devices. The locking devices on front wheels (except for quick-release devices) must not loosen or come off when a tester tries to take them off using a torque of 12.5 ft-lb applied in the direction of removal. Once fastened to the frame, the axle of the rear wheel must not move when it receives a force of 400 lbf for 30 seconds applied in the direction that removes the wheel.

(2) Quick-release devices with a lever must be adjustable to allow the lever to be set for tightness. Riders must be able to clearly see the levers and determine whether the levers are locked or unlocked. When it is locked, the clamping action of the quick release device must bite into the metal of frame or fork.

(3) Front wheel hubs that do not use a quick release device must have a positive retention feature that keeps the wheel on when the locking devices are loosened. To test this, release or unscrew the locking device, and apply a force of 25 lbf to the hub in the same direction as the slots in the fork. See §1512.18(j)(3) for this test.


I note in (3) above "Front wheel hubs that do not use a quick release device must have a positive retention feature." (Emphasis added.) This suggests that most manufacturers are in fact being cautious, since it's possible that a lever-action QR won't be the way someone decides to attach their front wheel...

But those requirements may have been re-written due to the lawyers!

We all know QR forks didn't used to have the 'lip'.

I, on the other hand, believe it's expecting too much of casual riders to know intuitively to put the QR on the non-disc side. Not everyone is mechanically inclined. It's also not requirement to know how to work on a bike to ride it. Nice to know, but not 'common sense'.

What IS common sense is the QR should be tight enough they don't work itself loose during the ride. If one isn't sure how tight it need to be , one should check it after a few minutes of riding.

My VO Randonneur has no lawyer lips, and the frame was designed and built within the past decade. Has anyone else bought a frame/fork or fork without lips?
