How many beginners don't understand how a QR works?

[Dusty Bin]

A word* of caution Ian.
I used to run my Dirty Disco like that but after two three issues of the QR coming loose for no apparent reason (eg I hadn't removed the wheel or fiddled with the QR) I've turned the QR round and it's now on the left.

I'd put the QR on the right because I'd read somewhere that it helped reduce the likelihood of the wheel being ejected under heavy braking. I'm not sure where I read this.......
There was no obvious sign that the QR had come loose since the lever was in exactly the same place. It was the nut on the other side that had unscrewed. I wonder whether the rotation of the wheel had caused it gradually to slacken.
I'm using Hope QRs in Hope hubs.
The most obvious symptom that the lever was loose was a very dead sound from the fork if I picked the front of the bike up and dropped it on the ground.
It happened most memorably on the Friday's Tour this year, just before we climbed a steep hill. We went down the other side at high speed. Ulp.

Needless to say, I check the QRs very frequently now and I would never remove the "Lawyer's Lips" from the tabs.

* Sorry, that's lots of words.

Mechanically, it doesn't matter one jot which side the QR is tightened. The wheel being 'ejected' under heavy braking is more related to where the disk caliper sits on the fork, or on the rear triangle for that matter. It's also the reason why a lot of MTBs are now using thru-axles, rather than dropouts.

Ok, you've convinced me..I'll give it a go.
Though have not had any problems in 12,000 miles.

I wouldn't bother. Philip Walsleben's mechanic puts his on the right, and he should know a thing or two about a thing or two.

Just been in my local Halfords - they also put them on the right, and left, sometimes on the same bike ..........

I was also thinking this!

If you've not had any problems over that distance, then you're probably OK as you are.
My issue may well be related to the design of the QR.

Yes, and it must be facing up and forwards into the frame triangle while the front QR must be facing up forwards of the fork.

Don't ask why, just do it right.

Both should be facing rearward for aeros!
