I hesitate to call myself a bicycle commuter as I only do it once a week (Dodgy weather and work schedule make it hard to do more than that) I've ridden in 8 times so far this year, a total of 10 times in the past ~5-6.

Here's a picture of my rig taken in my office (I keep my bike there during the day)

2003 Fuji Marseille (Reynolds 853 Cro-Moly ) with full Ultegra and full carbon fork, clip on aero bars and a seat post rack and trunk. Mity8 and Garmin ForeRunner 305 for data. 250 lumen SSC P4 flashlight from DealExtreme as a headlight and a Cateye LD1000 as a tail light in addition to a hi-vis yellow jersey. Also, if you look closely, you can see a bell on the back of one of the aero bars!

I wish my tires matched but I got a defective one from Performance and am waiting for the replacement. I use a 700Cx20 in the front (for now) and a 700x23 in the back. My route is mapped out so that I get smoooooth pavement for at least 90% of the time.
