Here's my commute bike: it's a Trek 7500FX. The upgrades I've added are: Cane Creek bar ends, fenders, Speedplay Frog pedals, Brooks B17 saddle, Carradice "Barley" saddle bag added today. The saddlebag may be a little small for commuting - they claim it holds 7 litres, but I plan to leave some items like spare shoes, towels, belt etc at the office in advance. Couldn't find my red blinky light today, but there is a strap on the bag for mounting one. Oh yeah - the tires are 700x32 Kevlar belted from Continental - never had a flat yet in approx 1700 Km. I now wish I had ordered 700x38 just to make the ride even more distinct from my road bike. Overall the bike is a nice mixture of modern and retro-grouch.
