I commute most days, 32 round trip miles with about 2000 feet of climbing.
Best part is the climb up Torrey Pines Hill.
My main bike, Douglas titanium frame with Reynolds carbon fiber fork - does everthing ok, not the lightest, stiffest or most comfortable, but a great balance of all.
Fully loaded commuter cockpit - HID light, Watt meter, GPS, Air-Horn.
Drive train (as if you care) Ultegra triple crank, Dura-Ace rear derailleur, Dura-Ace pedals, Dura-Ace chain, 105 brakes, Ultegra and 105 shifters and my new, favorite cassette: SRAM 11-26.
This is my new travel bike.

Not sure what year the frame is - 1995? - 9 speed components - Dura Ace bar end shifters, Campagnolo Mirage Triple crankset, Shimano Dura Ace pedals, Magura Hydaulic Rim Brakes, Velocity Fusion Wheels, Continental 4 Season 28c tires, SRAM 11 - 26 cassette, Koobi saddles (stoker has the PRS suspension).An Aegis carbon fiber bike.
