When I pull up at the University of Queensland bike parking area early in the morning, there are often hardly any bikes there. It's a long strip of very smooth concrete. Cuvy knows the area I mean. I'm often tempted, rather than riding along, swinging the front out then backing the bike until the back wheel is near the wall, to just hit the back brake and slide the back around 90 degrees and stop neatly. Of course, with a reasonably meaty and sporty back tyre, by far the most probable outcome if I ever gave in to the temptation is a rather spectacular highside, with potential for damage to the bike and me. And yet... Got any similar specific temptations that you *must* resist?
