Great video. It's tough to capture the salient details in 1 minute. Only suggestion I'd offer, if an update is in consideration, would be to explicitly advise lining up the cam lever where it does not conflict with anything that might prevent it closing all the way. The demonstration is great on this ... just consider adding the words.

Keep up the good work!

Alan, thanks for your comment. I trialled this vid on trade viewers first and I got some comments about 'protecting' the QR, esp on mountain bikes. Stray branches etc. However, advice from cycle engineers I respect says the clamping force of a QR (done up properly, of course) is way strong enough to resist ingress of 3rd-party objects. Your advice is sound, though and, in fact, adds to the assertion that maybe QRs shouldn't go too close to stays and forks?

Thanks, I will do. There's a whole series to go online.

That was a minute wasted. I need more info than that.

Not sure if it applies to all QR but in the booklet that came with my bike it says that you have to tighten the adjustment-nut on the other side of the QR to tighten it up. It specifically states NOT to turn the lever to tighten it. Just saying.

ON the London Skyride I happened upon a young lad with his rear tyre rubbing the nearside chain-stay. He didn't know how to operate the Q/R lever.

What about a video on the dangers of front disk brakes and Q/R levers? Isn't it about time the front caliper is mounted on top of the fork?

Q/R plus front disks plus rough surfaces [mountain bikes] are the required ingredients of a recipe for disaster, lawyers' lips or not.

naz8901- well the problem with that is you are prob turning the nut to tight, you see when you push down the quick release lever it is the equivilent of turning the nut 2 or 3 times, so dont have the nut super tight, you want it to be a little hard to push down the lever but not the point where you need too push down with all of your weight

Really good demonstration thanks!

thanks this video helped me to tighten up my wheel

[thatoneguy1990]

haha, i love how they give credit to Tullio as the qr guru

[naz8901]

I have problems with my quick release. I cant make it tight enough becuase the lever doesnt push down, and it doesnt align properly, help please

While this is not a forum on bike mechanics, you are partially correct. A properly tightened QR will compress the hub assembly approx 0.6mm. This means the hub bearing adjustments must be done and then checked with this compression for proper operation. See Barnett's Manual for reference. ...alan
