We recommend the Cervelo P-Series 105 Carbon Wheel Road Bike for riders looking to take the next step in their racing career, whether as time trialists or triathletes. Because every tenth of a second counts, this high-performance bike features a lightweight carbon fiber frame and fork for a smooth, powerful ride and is shaped with highly aerodynamic tubes to minimize drag and optimize airflow. The aggressive geometry, including a low stack and long reach, positions us to enhance speed and power transfer throughout our race to get us from start to finish as quickly and efficiently as possible. The bike even features aerodynamic storage options to keep our spare tubes, CO2, and tools hidden from the wind. Equipped with the 2 x 12-speed Shimano 105 drivetrain, we ride with crisp, trustworthy shifting at a 1:1 ratio, ensuring we have plenty of gear ratios to climb, descend, and sprint without running out of options. The diverse options allow us to shift between the 11-34t cassette range and 52/36t chainrings, which we comfortably control from the Zipp Vuka aluminum basebar and extensions with Microshift bar-end shifters. Although the shifting performance gets us up to speed, the Reserve 52|63 carbon fiber wheelset with Vittoria Corsa N. EXT TLR G2. 0 tires keeps us rolling with unmatched efficiency, grip, and optimized aerodynamics all the way through the finish line.
