[Closed] PSA: Quick Release/Disc recalls

crashtestmonkey - Member

it could, but you'd be relying on user competence

But the website has instructions for the user on how to fit the new QR?

You can, but it _may_ be more likely to slowly unwind itself in that case.

Ah, that solves it then, thanks

I know (hope) you're just trolling Gatsby but there are plenty of people out there who could get caught out by this and losing teeth or worse is hardly a fair punishment for not knowing how to use QR or being a bit forgetful.

In addition to people forgetting to do up, or not knowing how to do up a QR properly, that there is clear evidence of, I recon its entirely feasible that a QR could possibly be rattled, or knocked loose/into an open position.

Not to mention the fact that the force required to properly secure a QR (especially one to be used with Discs) is beyond the capability of a a fair few people, kids, elderly, a lot of women*, I know for a fact my mum can't do it, and my wife struggles to, hers have worked loose before simply because she cant do it up tight enough in the first place.

*not a sexist comment, not a sexist comment, not a sexist comment, repeat after me, not a sexist comment.

Is Gatsby Shibboleth? Never realised that. Shibby seemed quite a reasonable fellow (in the main), whilst the same cannot be levelled at Gatsby 😆

One presumes the delay after Trek did their recall suggests there have been more injuries, I can't believe it's taken the industry/CSPC this long to follow suit.

The point of a qr is to quickly allow you to release/change and then tighten the wheel. It needs to be done with a high amount of tension or it will eventually losen itself with the force of disc brakes. The fact that they are so particular about the tension and it's not that clear if you've done it right means you need lawyer tabs so your wheel doesn't fall out. Which of course, means that a qr is no longer that quick. And if you are in a race and not thinking as clearly as you should, then it doesn't seem like that great a design.

Add in the fact that these qr will potentially send you over the bars instantly if it comes lose I would have thought it should be recalled.

Blaming user error on a poorly designed product is wrong. Everyone defends qr's by saying it's user error when it's just a c**p design.

Indeed, to be honest, there is no good reason to have QRs on most* bikes, through-axles are obviously better in all regards but nutted axles would be so much safer and more reliable, and for general use would hardly be any bother, the only time the average cyclist needs to remove a wheel is when they have a puncture, and sadly the vast majority wouldn't fix a puncture themselves anyway these days 🙁

I think it all stems from the fact that 'quality' racing bikes came with QR's and therefore trickle down and the idea that it's some kind of mark of a 'decent' bike is what pushed them out to general bikes years ago, same as sus forks and 'mostly for show' disc brakes on catalogue bikes.

*as in ones used day to day round town for commuting and leisure, and in fact even most recreational MTB and road use...

Trek did this last month also read the article it's America only! ( so far) it's mainly on low quality hubs and QR's just turn the QR to the other side of the hub problem sorted

Bike radar article reads better

It's arse covering against dimwits who in reality would be best served by Darwin's ideas. Cheaper and better for PR to do this than do what they should really say which is hard luck ****wit. 40 years of Qr's and I have never had one come undone because I use them properly.
I despair of society nowadays.

Of course the alternative is do as Cotic did with forks and have the discs on the right.

or stop using QR's which were designed by a bicycle racer who wanted to be able to get wheels out of the dropouts quickly and easily and was prepared to accept some compromise on numpty-proofing/security?

through/bolt in axles make so much more sense both from a security point of view and structural stiffness.

Sounds like the smoker who says they've had 40 years of smoking and never once got lung cancer.
There are plenty of people who are experienced, not numpties, and yet their QR have come lose or even un-done. QR's are a rubbish design.
And you have not used a qr with disk brakes for 40 years.

Gatsby, I can only assume you've never had much contact with the 'average' member of the bike riding public.

Riding around with the following faults is common

This entirely.
They aren't stupid, dimwits or whatever, they just don't know because nobody told them.
Also, there's plenty of very experienced cyclists who make the most basic of errors too.
