I've mentioned it in this thread and others - riding brakeless doesn't necessitate skidding. There's no sense in hauling ass toward a busy intersection and then needing to lock up your back wheel to stop. That's just stupid.

The rear ThickSlick actually has one small skid on it - just because I wanted to see how sticky they really were when they were new (and they are very sticky) - but it literally didn't even leave a visible mark.
