That guy's all 'nuts to stem' when he's skidding though, so he's barely doing ***** to wipe off speed that just swerving wouldn't do. And that technique wouldn't fly too well with traffic around.

Once your cadence gets to its limit when you're bombing a hill without brakes you have to commit pretty heavily to your lines, almost like you might on a skateboard. Backpedalling isn't really an option, but skidding is. Once you've skidded down to an acceptable cadence then you can backpedal to maintain speed.

A front brake is a lot easier and more sensible, of course.
