This is the bike I had been using for a couple of years. '08 Novara Buzz (REI Brand), dece components, relatively light for an alloy frame and disc brakes. I recently purchased a new bike so I swapped the pedals from Shimano M520's to M24's and replaced the 700x32 street tires for some more dirt/trail friendly 700x42 cyclocross tires.
This is my new baby, it will be two weeks old tomorrow. '10 Giant Defy Advanced 3, 100% graphite composite frame and fork set, Shimano 105's ....
I know, it's not a typical commuter rig, it's a full on roadie, but then i'm in coastal San Diego county. Inclement weather is the occasional rain storm, and I admit, i'm a fair weather commuter. Also I like to get out on the weekends for some longer rides, and my commute route doesn't really take me through high density city streets.
