Somethings wrong there in that pic.
An opened QR lever doesn’t/can’t double back on itself. Even locked it can’t travel into the spokes. The amount the lever can travel is limited in both directions.
That’s not true with the kind of cheap QR pictured. The lever that sticks out of the side of the end cap HAS got enough movement to double back on itself (and stick in a disc and then finish under the fork as pictured). I’ve a bike with that kind of QR in the garage and I’ve just been in to open it. You can even see the curve of the lever in the picture above.
The QR has flopped fully open, stuck in the disc and jammed up under the fork, forcing the QR endcaps out of the dropouts, destroying the tabs.
This probably happened due to the QR not being done up tight enough. It may have happened due to a faulty OR that does not close properly, but if that is the case then the QR will still be faulty and impossible to close properly – this should be easy to test.
Of the bikes I’ve seen recently purchased, all but one have had the QR lever on the left next to the disc (the exception being a Trek hardtail).
But a quick whizz around the Trek, Specialized, Giant and Cube websites shows all the QR levers next to the discs. Every single one.
