Coming into work today I noticed that each time I braked I was getting a regular judder on the rear wheel. My initial assumption was that a spoke had gone and the wheel was out of true. Once in the bike shed I could find none broken so I gave the wheel a spin to see if I could spot the wobble. Nothing was wrong looking end on, but I noticed that the rim had a bulge a one spot. One of the problems with having rim brakes is thet they wear out the rims, so Mrs T is coming to collect the bike & me this evening and a new set of wheels are on order.
