2010-04-09 Fri - Hackney Drag Sprints

I'm not going to be able to go very fast tonight though, as I will either be a) riding on a brand new tyre (hence too much lateral resistance) or b) riding on a bald old tyre (hence too much tangential resistance). And my front wheel is out of true. And my chain needs oil.

I'm worried my hair may be sticking up too much thereby decreasing my aerodynamic properties.
