They'd be better if there was some sort of lock-out that prevents opening...I know if I used them,
I'd snag a branch or something and pop it open, and I don't want to ride with an open QR. It'd
probably never happen, but I wouldn't chance it to sve two seconds.
However, if they put a little tab/button on the end that you could hold with your thumb while
opening the lever, then it'd be very slick.
