Hi guys, I ride fixie, spd/ crank pedals, on the roads, between cars, fast, in North London. I do not have front brake, and obviously, neither rear one. Advice -> Be aware...as you build up strength on your legs and master control of your "horse" you gain confidence, you get "spiritually" connected, all get to be good! but chain tensioners can fail, chains can snap or come off and you might not be able to stop as you you'd wish to. I am not suggesting you to put brakes but just to be always conscious and more aware of that "things that can happen". Nathan
