I found this, and thought it definitely needed to go on here, enjoy!
Admit it: there is a mindset, a group of assumptions, and a whole set of experiences that set a "cyclist" apart from the vast majority of the populace that just rides a bike. There are the serious things, like an understanding of vehicular cycling, and the mundane things, like knowing where the good places to lock a bike are. Here are the amusing things that make us laugh at ourselves, and give those tell-tale hints that maybe, just maybe, you are a Bike Geek!!

2. At some point you caught yourself wondering if your bike might look good if you added fenders
3. You discover that you have forgotten to remove your reflective ankle straps hours after you have arrived somewhere by bicycle
4. You would recognize that threaded washer from a Presta valve stem anywhere
5. You KNOW what a Presta valve is
