TT's are big fun. When I first rode a TT bike, my first reaction was 'how the hell does anyone ride these bikes?'. So naturally, I bought one (on eBay, a year old 2007 Six13 Slice TT bike). I effed around with my position on that bike for a couple years, finally realized that the conventional TT bike wisdom (one size smaller than your regular road bike size) wasn't working in this case. I checked the geometry of the P3, decided a 56cm P3 might work better, then bought one of those bikes used off eBay for $2600. Mint condition. That's about $2K less than a brand new P3. The new bike fits me so much better. I'm actually comfortable in the aero bars. And I really do enjoy riding and racing the TT bike now. First off, you can't get dropped. There's humiliation when you're slow of course, but that's bike racing.
