[Closed] Front QR skewer keeps coming loose...

no matter how hard I seem to tighten it after one or two rides the wheels starts to wobble a bit which is obviously a bit worrying. Could this just be grit in one of the contact areas (stopping the proper clamping load) that needs cleaning up or is the skewer going to need to be binned?

get some cheap Deores from LBS maybe and try them and then you can check?

Is it a Hope skewer??

It is not really worth bothering with non-Shimano QRs, ime.

Plus you really should give them a quick check before every ride (and indeed mid-ride, if you stop give your bike the quick once-over) - noticing after a few rides is a bit scary!

The old hopes aparently worked loose on occasions IIRC. Not sure if the new versions are as bad but no experience of both 🙂

I had Hope ones (new style) and they were always coming loose. Same with the seatpost QR I had. I know other people who have had the same problem.

solution - get some shimano skewers. the only ones worth bothering with, in my experience.

Hope are fine. My 5 yr old titanuim ones have never given me any bother at all. I wouldn't bother with aftermaket ones again though, just not necessary.

If a skewer came undone on me more than once I'd bin it!

Found a pair of Shimano Deore ones on ebay for £10.99 so might just go for those!

The wheels were second hand and didnt come with skewers so I got hte skewers of a mate for free - have always used Shimano before

Make sure you haven't worn the drop outs thinner than the 9mm stubs that stick out of the hub.

A friend who used to just grind his qr up - ie hold the nut and wind the qr up tight is then flip the lever over, found that he had worn his drop outs (on marzocchi forks) so badly that the qr would but against the stubs from the hub..

Ahh well ignore previous post, there is another thought, do you go over centre with your qr or are you a 90 degree's man? (Or even less I have seen..)

Good, that is how it should be! I read soem cr*p somewhere about 90 degrees..

Oh well I cannot help after that, maybe the QR is worn...

This might be a stupid question, I'm not being patronising, honest (I know, difficult to believe on here) but are you using it properly? I've seen quite a few riders out on the trail who think the lever end is some sort of spanner they use to tighten the QR.

Just in case...

Open the lever, completely back on its self, tighten the nut on the other end lightly, close the lever past 180 degrees (flush with the frame or fork leg so it doesn't catch on rocks etc) It should require enough force to leave an imprint on the palm of your hand.

I have ridden for years and years and have used Hope, Shimano, Bontrager, Salsa, Brand-X and who knows how many other QRs, and not one single time has one ever, ever come lose. Not one. I'm sure people must be doing something wrong sometimes.

QRs do come loose, from my experience of having half a dozen riders with me whenever I ride, all of whom have been through a pre-ride check which includes the QRs. I don't know how, but they do. Not Shimano tho.

I agree. One of the few things on a bike, where no design has ever bettered it. They've just got it 'right'.

Driller - No i dont use it like a spanner tighten it up properly like it is supposed to be. Ill double check the clamping surfaces tonight but have ordered some Shimano ones in any case

Slight alternative method. I 'close' my lever, spin the other side up tight, undo the lever, put another 1/3 turn on the nut side, close the QR.

But then my frame is steel and magura forks have steel dropouts so the spinning isnt a problem.

my a2z ones are great. Prefer them to shimano's although shimano's do the job ok.

If by they, you mean him, and by him you mean Tullio Campagnolo, then you're right.

I've had DT ones come loose. Sobering to find them flop open when dismantling the bike after a ride. Happened twice, then binned them . Shimano or Salsa for me.

I have a similar problem with my Specialized Stout QR. Closing it is an all or nothing affair. Either too slack and it works loose quickly, or so tight that you can't open it again.

Well, I meant more that Shimano's particular version of the idea was 'right', really. I suppose there are tiny, subtle yet important differences in the design of different brands of QR. Having said that, I've used older steel Campag ones, and they've been fine too. In fact, it seems that newer designs that don't seem to be as good, really. And the more expensive, the less effective they are. Shimano Deore FTW.

I found the DT swiss ones that came with my bike difficult to set right and then came undone a couple of times !!!

Replaced with Shimano Deore - perfect

fronts come loose primarily because the use of a one-sided disc brake applies a torsional force to the bottom of the forks that has the effect of stretching the Q/R. When this stretching force is removed (brakes off) the sudden reduction in tension allows the Q/R to unwind. Titanium Q/Rs are worse than steel for this as they are more elastic.

Had it happen a few times in the Alps with a few different makes of (steel) Q/R. I now ride 20mm bolt-thru for this reason. The best Q/Rs Ive used were Shimano XTR (the only rear that could grip the hard 6/4 Ti dropouts on my old litespeed) and Salsa.
