Skinsuits

When Assos, the company that invented the Lycra cycling short (and hundreds of other innovative technologies), turns its eye toward reinventing the one-piece skinsuit, you know the results are going to be impressive. Their newly minted CS.Uno AeroChronosuit was fast enough to help Swiss star Fabian Cancellara win a gold medal in the time trail at the Beijing Olympics and gold in the 2009 Elite Time Trial World Championships. Not for everyone, but for those that ride time trials or compete on the velodrome, it's as good as there is if not better.
