Skidding on the trail is bad, okay? But skidding on a fixie is only harmful to your tyres, and leaves some cool marks on the tarmac. This is the run down to my flat's front gate, the green one there. I practice my skid stops here rather than in the traffic. I've just discovered that having your pedal at 6 O'clock, rather than 9, is easier on the knees and produces a longer lock up. Now, back to work on those track stands.
