Here are some shots of my newest commuter bike, a Gunnar Crosshairs. I just had it built and have not ridden it to work yet, but it's ready to go. Added the rear rack and the reflective tires for commuting, and I have some SKS Raceblade fenders that I can strap on when the weather is iffy.
The Crosshairs is replacing my Gunnar Sport, which was a nice bike but I prefer the versatility of a cross frame. I've got the Sport for sale in the market place forum here.
I've also been commuting some on my Ritchey Breakaway Cross that I picked up used earlier this summer. I don't want to put fenders on this bike since I also use it off-road, so I only ride it on days when rain is unlikely.
