I'm fixing a flat tyre a second time within one hour. I was having a little race with another cyclist on Friedrichstraße when a little piece of glass stopped me pulling past him. The good thing about Berlin is that you don't have to walk very far to come across some friendly bicycle shop. I bought some Flickzeug for 3,95 Euro and the shop owner gave me all the tools for the job. Now I'm waiting for the rain to stop.´
