limax2: Funny you should say that, I tried to ride off on Saturday forgetting the disc lock. Was only nudging out so no drop and no damage done but it made me think that a fiver for a disc lock cord is cheaper than the alternative...
fazersharp: There are lots of little things that suggest the bike has bee dropped at least once. Being a novice, I didn't know what to look for when I bought the bike. Of course, now I've got it, I've met loads of people who would have been willing to come with me for advice!
