Bob Chambers' Cervelo P4

Bob Chambers' Cervelo P4.
Sleek. Fast. Stealthy. Those are three words you might use to describe the Cervelo P4, the Canadian firm's follow-up to its legendary P3C. This is Bob Chambers' ride, tricked out with a $1200 Zipp crankset and the high-zoot Hed Corsair aerobars
What the rider says:
"I purchased the frameset and built the rest up from parts I harvested from old bikes or bought new/used. The Zipp Vuma Chrono crankset seemed like an insane purchase until I rode it. It's unbelievably stiff and gives the impression of tremendous power transfer. The V-Flow MAX saddle is absolutely the best saddle I've ever used for riding aero. I'm riding the HED Corsair, which has very comfortable Lazy S-bend extensions, and nice return springs in the integrated brake levers."
"Wheels are a HED Jet 90 and Jet disc. The disc deserves special mention. Hed took my old C2 Flamme Rouge Jet disc that was rubbing in the P4 chainstays and re-built it with narrower spoke covers and a standard 19mm rim. Fits the P4 now with room to spare. There's a bottle cage mounted to the aero extensions. I keep the P4's integrated bottle in the frame for assumed aero benefits, but I use the cage on the bars to carry hydration when I'm racing. This bike has been the most difficult I've ever worked on. When I have to work on her, I hate her. But when I get to rider her ... oh my! I still have my P3C. By comparison, the P4 is lighter, it handles better, it has a more solid feel."
