After about a 4 year hiatus from the sport, I decided to get back into it, both to keep in shape as well as for the enjoyment of it. Spent some time testing bikes and finally settled on a Cervelo S3. My LBS was really a pleasure to work with. Spent over 4-5 hours on me each day for about 3 days in a row (picking bikes, fitting me, answering dumb questions). They also threw in a lot of free goodies (spare tubes, water bottles, flashers, lots of little things here and there). Just picked it up late last night and took it for it's first ride today. Setup includes, among other small tidbits:

Zipp 404
Michelin PRO3
Campy Super Record 11
Fizik Anatares Carbon saddle
Garmin 705
Sidi Ergo2
Look Keo Carbon pedal
Ritchey ProII Carbon handle

Total weight including all accessories: 15.25lbs (6.9kg)

Ride was 20 miles, ~70F, on all dry back roads (aka no traffic). Mainly hills with a good section of flats in between. I managed an average of 16mph, 70rpm cadence, and 180bpm heart rate (I'm only 20y/o 125lbs, 5'10"), with a max of 34mph.

Bike was surprisingly comfortable. I picked up a pair of Assos FI.13 S5 shorts, but made the horrible mistake of wearing underwear underneath them. Wound up bunching up and turning into a pain in the a**, literally; would have been excellent otherwise. Even over the brick / cobblestone paved walkways along my route, no loose teeth or need to come off saddle. Around corners, bike felt extremely solid. Tires held like glue, and was able to get some nice speeds around corner. Granted I am rather light so even if the bike was made out of spaghetti, I'm not sure I'd be able to flex it. SR11 did give me a little trouble in the back, taking some time to switch down to the lower 3 or 4 gears as cable began to stretch out - a quick turn of the fine adjustment nob fixed the issue. Found the Look pedals much easier to get out of then the Shimano Dura-Ace (were on previous bike some time ago) but, at least for me, somewhat more difficult to get into.

Garmin was perhaps the best spent money on the bike. The amount of data it provides is unbelievable. Everything from sunrise and sunset, average max min and actual cadence, speed, power output, road and topographical map, turn by turn directions, elevation history graph, and a million other things. Easy to see in direct sunlight even without backlight, and very solid construction. The ability to throw the data onto the computer and analyze it further is also a huge benefit for me.

My biggest problem was fatigue in my lower legs. I could have gone all day except for my calves. My thigh muscles weren't even mildly soar, but my calves were killing me. I think a lot of it has to do with the way I was peddling. I jumped on the trainer when I got home to see if I could figure out what was up. I think I was trying to peddle by pressing down on the front of my foot, instead of, what now seems somewhat easier, pulling down with my heel. I plan to make another trip back to my fitter and see what he thinks, but any suggestions in the mean time would be greatly appreciated.. My neck was also somewhat bothersome, undoubtedly due to the unusual angle of looking up.

In any case, some quick pictures for your viewing pleasure. Please feel free to make any comments, ask any questions, or provide any other feedback.
