Go here to see what I used to ride to work. Thanks to an early - and incredibly generous - birthday present from my wife (thx, Elysa), I rode the beautiful Giant Seek 2 shown above to work today. It's considerably lighter than the Bridgestone, has disk brakes, Shimano shifters, and is a pleasure to ride uphill. I had the fenders added for rainy days. [NOTE: The dorky mirror attached to my helmet is the EVT Safe-Zone. I know, I know. But it's real sturdy and gives a clear view of what's behind me.]
