Front QR Safety Recall (USA)


By JohnH - Posted on 01 October 2015

NB: Originally posted elsewhere on the Global Riders Network and appears via syndication.

There is a safety recall in relation to the potential for certain types of QR levers to contact a disc rotor if they unlock during operation. From what I have read this can cause the front wheel to lock and I believe a rider was seriously injured as a result in the USA.

This recall appears to be in the USA and I'm not aware of anything in Australia at this point in time but am going to try and get more information tomorrow as I have identified one bike in my family that fails the test.

It can be argued that the QR should not come loose if tightened correctly but given that this has been identified it may be worth follow up on the grounds of safety.

The bike I identified is a introductory level MTB so please check all bikes including those used by children.

In my opinion that's a pretty stupid recall, it's almost like saying an axle is at fault if it comes loose and the nut falls of.

If it comes undone and you have hydraulic brakes the movement would force the pads to retract and they probably wouldn't work so this may be of benefit.

The only real way that can flip undone is user error and possibly a loose lock-nut on the hub bearings, or I suppose if the cam is so worn it doesn't lock properly.

Doesn't everyone put 9mm quick release levers on the non-disk side?

All74, I think it's due to the fact that since you can't have the lever positioned downward, which would make it very vulnerable, it has to be positioned upward.
Being on the left hand side, if something should catch it, it'll spin towards the rear, which will tighten it against the nut on the other side.
If it was on the drive side (RHS) it would unscrew the skewer, potentially causing it to come loose.
It's true that on modern mountain bikes, some (most) fork legs protrude so much from the drop-outs that the lever hits it before it can unwind.
It's still relevant on road bikes so I guess it's wise to have just one rule and avoid possible confusion.
Anyone has a different idea?

I always ran the front quick release with the lever on the non disc side. Do it up properly and check it before riding = no problem.

Al that does make sense, maybe i'll change them (and check they can't foul the disk!). Flynny your right and I've never had one loosen right off either, but I have noticed, that at times, my 9mm QR bikes seem to develop movement in the dropouts which caused vibration when I brake, and is cured when I tighten them up super/hand brusingly tight, might be just a 9mm QR thing rather than working loose.

Have you ever put some chain lube on the moving parts? Makes the QR clamp firmer and last longer, once they wear out they are much more likely to pop open when riding.
