Polo Bikes

I think the front wheel is generally where the action is.. spokes or wheel covers can rub off someone's leg with not much problems, but if you got the teeth of a fixed sprocket rolling around and making contact, the potential for slashings is increased.

Its funny how there is such a bike uproar about the exposed sprocket, but when I pointed out that brake rotors were rather dangerous in the throw-in safety thread, it seemed to be dismissed as nonsense.

A rotor is way bigger than a sprocket and has large openings for things to get stuck it. Squirrels get stuck in downhillers brakes all the time. Whatever gets stuck in will get chopped off, unlike a sprocket which would do very little. A gash at worst.
