Adjusting fit is simpler on the Cervelo P5 Ultegra Di2, a carbon triathlon and time trial bike with a one-piece front end that is easier to assemble. Stack moves up to 40mm, extension tilt runs from 0 to 30 degrees in 5-degree steps, and the basebar drops 10mm from the previous P5. What Our Gearhead(R) Experts Are Saying:"My hands stay on the levers and bar-end shifters for the whole ride, so Dura-Ace there is what I feel on every shift and every brake pull. Ultegra handles the crankset, derailleurs, and cassette further down the bike, where I'm not touching anything."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.
