For what it's worth, people seem more interested in my '56 Raleigh Trent Sports than in anything else I have. It has a 700c rear wheel, 26" front wheel, drum brakes, a two-speed derailleur AND a Sturmey-Archer 3-speed hub, and the front mudguard (fender to americans) is made from duct tape, two lengths of old brake cable housing and the fitting hardware from the SKS mudguard I used to have before I snapped it. The frame has rather an unsightly repair courtesy of a MIG welder, the chrome is totally knackered and the rear rack is made out of aluminium flat bar stock. I've spent maybe 100 quid on it in total, and in comparison, nobody seems to notice much about my other bikes, some of which are worth ten times that. The mudguards made from an old BMX tyre that I have on my folding bike do attract a few comments, though.

Edit: Wow, this post really does sound like I'm bragging. Wasn't intended to be that way, but it's gotta shows something about the workings of my mind if I brag about having a mudguard made of duct tape....
