Are these are easily defeated?
I read that these are easily defeated on several cycling forums:
1. By a magnet.
2. By brute force by twisting the quick release 180'
3. By another easy method?
Is this correct? is it possible to bypass this security by these simple methods? I have asked this question of Zefal on from their website and have received no response.
Im just asking this as this is what the biking community is saying in all their forums. I would like to buy these but it is no point me or any other customers buying these if our security is going to be compromised - not a good result for all.
We (the community) are not looking for the standard 'well if a thief really wants your bike' response, but specifically related to these skewers and the above 3 questions.
Thanks and we look forward to your trustworthy advice!
I was so concerned by your question that I just went to have a go at stealing my own front wheel.
In answer to question no.2, this is not possible if the skewers have been fitted correctly. Part of the mechanism stops you from doing this.
I guess brute force can overcome any physical mechanism - it just depends how much force is necessary. I don't think you could force the mechanism by hand, and I'm not going to try destroying my own bike with a hammer or anything!
Also, in response to the standard "well if a thief really wants your bike" response, I think the key is just to make your bike less susceptible than all the others it's parked with. If you were out looking to steal a bike, I reckon that you might have a pair of wire-cutters with you, but not a hammer (assuming that even works). On that basis, I'm happy with the product.
I haven't got a magnet here (at work) so I'll try to answer that question later on.
