Hello,

Anybody used these?

Are they any good?

Thanks

Steven

    Sounds clever - though perhaps a little annoying when you want to get your own wheels off? Probably worth that small gripe, though, if you're at high risk of wheel theft.

    Does sound clever, but I've got a theory that these might not be as secure as suggested.

    They obviously have a gravity locking mechanism where something drops in or out of a slot when the bike is the right way up. However, rather than having to turn the bike upside down to release the lock, it might be possible to do it by giving the wheel a quick jolt. Coordinating that with opening the quick release might be tricky, but it wouldn't surprise me if it could be done.

    I use these on my commuting bike:

    They are light and easy to use. I haven't had my wheels stolen yet. You need to carry around the key though, but I just keep it in my panniers.

    I saw those reviewed in a French cycling magazine when they'd just brought them out, but at that time they weren't available in the UK. I thought they looked good and had it in the back of my mind to keep a lookout for them, but this is the first time I've seen them advertised - thanks for the link! May well put them on my Christmas list.

    Hmm. I wonder if there's a risk of them getting jammed in the locked position, if some dirt gets in for instance...

    Hmmn, so, new to the market then? I wonder if C+ will test them?

    I had those on my station bike, but they don't provide as much force as a QR skewer, as I found out when I accellerated away from the lights and my wheel shited in the dropouts, jamming against the chainstay.

    Gone back to QRs and carrying an extra lock.

    Maybe a magnet might trick them to unlock.

    If you were determined enough to be carrying special kit to get them off, you'd just get some mole grips on the other end of them.

    Even something far more secure like pinhead locking skewers aren't resistant to a dremel. They're just a delaying tactic. I'd be concerned with reliability on those zefal ones.

    Oh, I haven't had this problem in a couple years of using them. Obviously not giving enough boot at the lights :wink: They also stayed in last week when I got a stick stuck in my spokes and buckled my wheel :x £16 later for a wheel true....
    Anyway, on that note I will give them an extra tweak tonight before I ride home.

    I just use Halo bolt throughs, very cheap, very light (<80g/pair), and as secure as most bits on a bike (3 allen keys and you can strip most of a bike anyway!).

    i bought these pinhead ones http://www.wiggle.co.uk/p/cycle/7/Pinhead_Duo_Pack_Locking_Skewer_Set/5360029668/ recently and they seem ok. Dead easy to fit & seemed to have no problem tightening them.

    Actually I didn't know about the zefal or the other option in the thread, although they seem a slightly different idea.
    For some reason there was no link to other products on wiggle when I saw them, didn't realise there were alternatives... doh. Lesson learnt there.

    Next lesson of course being when I get a puncture & discover I've lost the key...

    A Magnet special kit? Yes maybe mole grips could but if a magnet works, much easier and most people will have a magnet somewhere.
