This week has been very busy for 101bike.com. I was pretty occupied with the interviews and therefore the break research slipped a little bit, unfortunately. My research regarding brakes has been mostly desk research, with help from Google. I read about different brake systems for different usages and visited some websites of brands offering brakes.
For my break research I ended up at Wikipedia and the website from Sheldon Brown.
Good information, Wikipedia being more general, Sheldon for more in depth stuff.
