• I'm a new convert to fixed-gear cycling, having recently bought a Specialized Tricross single-speed, faffed about for a month with the freewheel, and finally gone over full-time to 42:18 fixed, with lots of hill riding on the North Downs. I'm still a little nervous on the road, and well aware of my limits.

    Novice though I am, I've quickly come over to Sheldon Brown's view that rear brakes are of very limited use, and it's better for cyclists to learn how to control their machines in other ways. That goes for single-speed and geared bikes as well as fixed.

    As for bikes fitted with freewheels, I think it irresponsible for riders to remove their rear brakes. Never mind the law; common sense should dictate that the brakes be left on and used where necessary (i.e., at least in emergency situations).
