I was always thinking if I had a longer padlock like that will it actually do the job of securing a wheel? Well, it definitely more hardly than a cheap cable lock! How about some shorter and than maybe just lock the rear wheel with the part of the frame nearest the front dee, albeit just slight on top.
Know what I mean? Damn, some bike shop should sponsor me to keep coming up with ideas to deter thieves.
