When it comes to endurance training and racing, we need a bike like the Cervelo Caledonia 5 Rival eTap AXS Road Bike to keep up with our heavy workloads. This carbon fiber bike features a unique geometry that keeps us in a powerful position with optimized aerodynamics while ensuring we stay comfortable and relaxed to keep us pushing past that 60-mile mark and beyond. The carbon construction is lightweight, durable, and stiff to optimize power transfer and response, and the tapered carbon fork absorbs shocks and vibrations to minimize fatigue as we ride over not-so-smooth terrain. Spec'd with SRAM's 2 x 12-speed Rival eTap AXS electronic drivetrain, we can be sure we have plenty of gears, long-lasting battery life, and reliable braking during our epic adventures. We shift with ease between the 48/35t chainrings and a 10-36t cassette range thanks to the AXS-enabled shift-brake system that controls the front/rear derailleurs, as well as the hydraulic disc brakes which stop on a dime. We are also provided with proven Quarq reliability and accuracy power readings at a /- 1. 5% rate with the integrated power meter platform inside the DUB spindle, making it easier than ever to track our training data in real-time. Finally, the aluminum Vision Team i23 Disc wheelset, complete with Corsa N. EXT TLR G2. 0 tires, keeps us rolling with speed over bumps, smooth tarmac, and anything else we may encounter on our next adventure ride.
