Hi! I've been looking at the Forum posts on this sight for months now, and I thought I'd join in. I'm 55, in pretty good shape, and have been riding seriously for the last year and a half.
Here is a photo of my bike. It's a Pinarello F4:13 with all Campy Record components. I really like the Zipp stem, with an FSA classic bend bar. The Fisik Aliante saddle is fairly comfortable. The Zipp 303's shown on the bike weigh in at 1029 grams, especially light for a set of 303's. The bike weighs in at 6787 grams/14.96 pounds with a Tiso alloy 13-29 cassette (useful for climbing the hills around here). I like the sticky Veloflex carbon tubulars, and Look Keo cro-moly pedals. I alternate the Zipp wheels with a set of Mavic Ksyrium SL's with dark blue Michelin Pro2 Race tires.
I hesitated to get the Zipp wheels because they had red and white decals on them. To my mind, the stock decal colors esthetically clashed somewhat with the carbon blue frame of the bike. I had Zipp send me some 303 decals, and had FastSigns in San Mateo scan one for me (an idea I picked up on a recent thread on the Weight Weenie Forum). I had FastSigns change the Zipp logo banner color in their computer vector file to a blue that matched the Pinarello frame. Holly at FastSigns was incredibly helpful in guiding me through the process. They then printed out two dozen new decals on a very thin, and very sticky plastic decal film, printed over a black base layer, that covered up the original red and white decals. They came out looking great!
I love this bike, how it looks, and how it rides! A lot of other riders come up to me and ask how I like the Pinarello. It's great!
