Xena XZZ6 Disc Alarm Lock: A Review

no, that one is not the same model .. there was no product code so i couldn't find any info on it .. i think it's an older, out-of-production one. plus, I wanted it in black and they only had yellow, so I got the xzz6 instead..

Just did this minute. Decided would be very good to have one for when my bike is in our shared hall overnight (shared with one person we trust completely but I worry about thieves getting through the front door and stealing the only thing of value in the hall - plus nothing to lock it to). Every time I hear any noise out the front I always worry it's burglars, I'll sleep better with one of these.

Are you going to tell me they've gone bust or something now?! It did seem very cheap.

Oh FFS! So should I ring up and cancel then? I don't care about the colour, is there any advantage to the XZZ6 over the one I've ordered?

If you ordered anything other than an xzz6 it might not fit your chainring. The Xena's are primarily designed for motorbikes, the xzz6 is the only one that says it will fit on bicycles as it has the widest 'jaw'. It doesnt have the product code on that site - so I would double check what you've ordered - even though it looks like the right one in the pic.

Eek sorry Fox! I hope it's all A OK.

No worries, just emailed them now. I could always send it back under the distance selling regs..

well from what I read, the cheap one push out 100db, whether the other one push out 110db.

while it's a 10db difference, it's still a big difference.

The decibel scale is a log scale so as ed said the difference will be pretty big.

Yeah I did Jammy, well spotted thanks, will update when it arrives.

I ordered the one from your link Jammy. I'll check it again when I get home but I think it's just a bit bigger and heavier than Clefty's.

Not sure about quieter - when I set it off in testing I had to throw a duvet over it and run out of the room holding my ears!

just checked it, and it is 110db after all.

Unfortunately I chucked out the box and I can't recall exactly which model it was - but I remember googling it at the time and finding out that it generally retailed for more that the xzz6 and that it was about 100g heavier.

It's currently hanging off my back door handle as an el cheapo burglar alarm...

Not bad not bad. And what thickness stuff can it be slotted around?

Jammy,
nope, but l will tomorrow! Will want to know which model it is as its hard to make out.

You could get anything up to 7.5mm in the slot.

Dunno if Clefty's arms differently or not but this one seems to rely on some metal breaking the plane of the sensor between the slot to set it. So I'm not sure how the ideas of using it on spokes or saddle rails would work, as I expect it would just hang there without the plane being broken, unless it were balanced carefully. It's ideal for my chainring though...

I would test it out more - but it wakes up the neighbours and scares the cats to death!

Nice review clefty.

Yep, I've found it does need metal to break the sensor plane - my saddle rails will not work with it unless finely balanced. I'll update the original review.

They have just emailed me back to say this is the one I have ordered for £19.99 - weird it is elsewhere on the site for that price!

110Db and a 7mm gap height - so do we think this will work? I'm guessing yes if the other one is 7.5mm and will fit two chainrings (I only need it to fit one).

Thanks for the review. I bought a cheaper knock-off version and it's crap. I could add another tenner and buy this one.

0.5mm is a really tiny difference, to put your mind at rest, most chainring are usually 4 to 5mm thick (I've just measured the two chainring I have).

Thanks Ed - that's what I thought. Bargain then!

Just measured my Sugino 75 ring and it's 4mm max, so giving the go ahead.

Has anyone ordered one for £20 from the site I linked?

Yeah. I did. It's a slice of fried gold.

But... I reckon I need some ear protectors to test it out in the flat before I let it loose on the public. Find the best spot for it. Don't want to be the cyclist equivalent of those annoying pricks whose car alarm keeps going off at the slightest provocation. And there’s no way to turn it off remotely (though that’s hardly cause for complaint given it was 20 quid).[/FONT]

I tested mine outside my block of flats - apart from some confused looks it was fine.
Don't test it in enclosed spaces, I've had it accidently arm in my bag before when a piece of metal touched the sensor - it went off just as I opened the bag to get to it, so I got a face full of pain.
My ears were ringing for ages.

Just had mine drop on the desk - it's having a trial by fire in deepest Camden tomorrow.

May try and scare the cat/girlfriend with it tonight

Mine twarted two scrotes in Southall this afternoon. I heard an alarm go off and nipped outside the shop to check and saw them running. I went to check the bike and a shop assistant came out and said they were hanging around the bike but left smartish when the alarm went off.

Two thumbs up.
