What Our Gearhead(R) Experts Are Saying: "Between the fast carbon frame, Shimano 105 drivetrain, and Reserve aero wheels, the PSeries 105 Race is a nononsense tri rig that balances performance, storage, and value."We turn to the Cervelo PSeries 105 Race when aerodynamic efficiency and mechanical reliability move to the forefront. Its carbon frame carries cues from Cervelo's P5, refined for speed but engineered for adaptability with a Dsteerer, rounded stem interface, and generous fit range. Using a Shimano 105 R7100 2x12 drivetrain with 52/36T crankset and 1134T cassette gives us smooth, dependable shifting when every second counts. The Reserve 40front and 44rear carbon wheelset keeps momentum without sacrificing stability, rolling on Vittoria Corsa N. EXT 700x29c rubber. We pack neatly using the Smartpak 400 bento box and inframe storage for tools and tubes-fully integrated for aero efficiency. The PSeries 105 Race blends triathlonfocused performance with mechanical simplicity for the athlete aiming to push faster, smoother, and longer. 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.
