I love Velominati. If it’s not part of your regular surfing, I’d suggest bookmarking it. Here’s a little blurb from their series of ‘looking pro':
“Rule #22 is perhaps the most complicated Rule amongst the (currently) 85. Part of the complexity springs from the fact that we are all very attached to this small cotton cap. Off the bike, it was once a badge used to recognize one of our own; now it has been taken over by the hipster crowd which subsequently ruined it for those of us who wore this hallowed garment with pride. Our response has been to refrain from wearing this garment off the bike and resort to other badges – such as Rule #33 compliance – to identify our own. That said, some of us, in the spirit of Rage Against the Machine, refuse to lay down arms and are fighting to take the power back and callously wear our caps regardless. (Guilty.)”
