I came across this lock on wiggle which looked pretty good for when i only want to lock the bike outside a shop/cafe for a couple of minutes. I'm thinking of those lovely long summer rides to come this year. http://www.wiggle.co.uk/ProductDeta...dID=5300006185&N=Abus CombiFlex 202 90cm Lock Any idea if it's any good. Or alternately suggest another of around the same price. One that would fit in a back pocket or saddle bag would be good.
