Chrome Bags made something called "The Sherman" which was supposed to be designed for track riders and got very good reviews. But not sure whether it was ever sold in the UK or even if it's still made. I just use a big Timbuk2 holdall and the Keirin tote for tools, etc.
I looked at the Sherman when at the Chrome store in NYC and it was interesting idea but I thought it lacked enough pockets pouches etc for carrying things other than wheels. Looked good for that though.
