Broken qr
I was out on the ss today
started a climb when the qr snapped off drive side at the tug nut
Fatigue?
Too tight?
9x135mm

Re: Broken qr
If it's aluminium it might be fatigue. I swapped mine out for a steel one.

It's a halo one been on the bike about 5 years so it could be fatgivewhitestone wrote:If it's aluminium it might be fatigue. I swapped mine out for a steel one.
I use it alot because of the slot drop outs readjusting the chain

Re: Broken qr
I had a Halo one snap on the HT. Wheel moved in the (slot) drop-out descending the Devils Staircase, loosened it, realigned the wheel, went to re-tighten and snap.

Not the best place for it! at least I was only few miles from my vanBearbonesnorm wrote:I had a Halo one snap on the HT. Wheel moved in the (slot) drop-out descending the Devils Staircase, loosened it, realigned the wheel, went to re-tighten and snap.
Still using halo ones ?

Re: Broken qr
Replaced with Shimano.Still using halo ones ?
The Halo one was a bolt-up one rather than a QR ... I do wonder whether or not that could lead to over stressing the things when making sure they're fully torqued to FT?

Re: Broken qr
If you are regularly checking torque values then you should always back off first.

I converted over to Shimano on the Swift and they were good
The Hopes i had on previously had issues with the exposed cam bit becoming scored and subsequently not holding strong enough despite being fully clamped on

Re: Broken qr
jay have you got tug nuts on both sides, I always had 2 and never needed to overtighten the qr, shimano for me as well
it's not that I can and others can't, it's that I will and others won't.

'FT' engineering speak for f*cking tight ... no torque wrench required.If you are regularly checking torque values then you should always back off first.

The qr broken on the nut side when riding not tighting it

I've taken a halo one off my cx bike for now
I'll have a look at Shimano

Re: Broken qr
Funnily enough, I read an article on QRs in a magazine. It was about lightweight skewers and Shimano came up as one of the heaviest but they claimed the extra weight penalty of the Shimano skewer was more than worth it due to their strength and reliability.Bearbonesnorm wrote:Replaced with Shimano.Still using halo ones ?

The magazine also claimed that it was probably one of the worse areas to be a weight weenie and they may have a point

Think I'll end up buying some Shimanos

I use Salsa ones, they're stainless steel and I've never had a problem, I also

Re: Broken qr
Shimano here on my SS. Only one tugnut on the DS - never been an issue.

Re: Broken qr
I'm a Shimano QR user, the ones with a side-lever rather than over-the-end lever (you know what I mean!) - they seem to have a more secure action.
All this FT talk, surely that is defeating the whole design purpose of the cam action of a QR skewer? I've seen so many users tighten the nut by spinning the lever end then really cranking it tight then having to force the lever over; this effectively makes the design ineffective! Surely the idea of the cam is to take up the elasticity and shouldn't require any more than a modicum of leverage to work? Too tight puts much greater stress on the skewer and would be more likely to cause/accelerate failure. [I am not an engineer ]

We go out into the hills to lose ourselves, not to get lost. You are only lost if you need to be somewhere else and if you really need to be somewhere else then you're probably in the wrong place to begin with.

Re: Broken qr
I've busted a shimano one - after several years of use to be fair. I've also had a couple strip threads (bodgeable by carrying an m5 nut) and one lever snapped. Dunt matter how strong it is I can always FIU but Shimanos do seem to be more durable than most.
Re: Broken qr
I've used DT Swiss RWS skewers for years with no problems. Not cheap though.
Re: Broken qr
Ive got a DT Swiss RWS 10mm axle on my posh bike ant it been faultless so far
