My 2008 P2 SL (now called the P1). It's mostly Ultegra, including the pedals. The wheels are used H3Cs, with Vittoria tubulars.
The Renn disc is a used clincher; I bought it before I found the HEDs, and now may look to trade it for a tubular version so that I avoid a Frankenset on flat courses.
It's been a great ride - I've always lusted after even juicier machines than this, but I maintain that it's still far better than its engine,
so I'll just keep on it until I make it to the pointy end of my age group!
