Maybe I'm just a lucky bast&%d but I've been riding with QR's since '72 when I got my first brand new Peugeot U0-8. Sold it in '85 and bought a brand new Peugeot PH10LE. Guess what. It had QR's as well. Guess what else. I'm still riding that same PH10LE all these years later and I have never had problem one with them. I guess I'm just lucky. And no lawyer lips on either of them.
