Interbike: Cervelo’s new P4; Storck gets stiffer Road rigs from the lights and glitter of Las Vegas Share on Facebook Share on Twitter Share on Pinterest Share on Whatsapp Share on Reddit Email to a friend By James Huang Published: September 25, 2008 at 10:00 am Cervélo officially unveiled its stunning new P4 during the first indoor day of the Interbike trade show. Cervelo The new P4 is definitely more of an integrated chassis than its P3C forebear. James Huang The dropped down tube helps smooth airflow coming off of the front wheel. James Huang Custom headset spacers mate perfectly with the bottom of the 3T Ventus stem. James Huang Internally routed cables on the Ventus bar also help clean up the front end. James Huang The frontal profile is rather clean. James Huang Cervelo says the new P4 is substantially faster than the P3C. James Huang An integrated bottle smoothes airflow around the bottom bracket area. James Huang Cervélo says the P4 is faster with the bottle installed than without. James Huang The giant asymmetrical chain stays stiffen up the rear end. James Huang Even with their girth, Cervélo says the new chain stays are more aero than before. James Huang The rear triangle is particularly clean. But hey, where’s the rear brake? James Huang With no brake mounted up top, the slim seat stays are free to sprout cleanly off the sides of the frame. James Huang We’re guessing air flows neatly off the rear edge of this area. James Huang The rear brake is a custom Cervélo design and is housed entirely within the chain stays. The little gold knob is the quick release. James Huang aluminium dropouts incorporate threaded adjusters. James Huang The aero post offers two offsets… James Huang …and the neat wedge-style clamp means there’s no protruding clamps. James Huang Naturally, aero tube profiles are used throughout. Cervélo Interestingly, the frame bears a giant ‘P4’ logo on the down tube instead of the usual Cervélo badge. Cervélo The internally routed cables feed into the housing stops accessed through the little port in the down tube. Cervélo
