I love my P3SL - I've had it since early August 2004. This bike is a rocket! I run a 55 X 42 - alongwith a ZIPP 606 wheelset. I'm getting faster as I get older (47 years of age) - using this type of equipment. September '06 rode a 55:19 40K TT -- 2 min 30 sec faster than the previous year (ZIPPS certainly helped). It is incredibly stiff - awesome power transmission, and even with two spacers on the stem I'm way more aero than I've ever been. It's a pleasure to ride into headwinds. The only blight on this bike is the reversible seatpost -it's a pain in the ass to flip it around easily i.e. I like to ride it way forward for duathlons, but need to flip the post around to make UCI legal distance from tip of seat to centre of bb for road TT events.
