What's your favourite gear ratio?

Fit a brake. You would be a danger to yourself and other people without one. What would you think of someone driving a car with faulty brakes? Probably that they are a bit of a cunt.

What would I think of a novice fixie skidder crashing into someone because they don't have brakes and had some vain excuse about their handlebars?

Don't be a cunt!

He won't crash tho as that would probably scuff/bend the handlebars.
