The Cervelo P5 Dura-Ace Di2 is a carbon triathlon and time trial bike that holds a wider range of positions than the previous P5. A new one-piece front end is simpler to assemble and adjust, stack now adjusts up to 40mm, and the riser tilts the extensions from 0 to 30 degrees in 5-degree steps. The basebar also sits 10mm lower to cut frontal area. What Our Gearhead(R) Experts Are Saying:"The dual-sided meter reports left and right output separately, so a combined number never hides an imbalance between my legs. Over a long ride I can see which side is doing more of the work."Heads up! We do our best to keep bike specs and images current, but occasional component changes can happen without warning, and sometimes the photos might not show the exact build you'll receive. If you want to double-check the details, our Gearhead(R) Experts are always here to help.
