Name: Cervelo P Rival AXS 1 2025 - Road Bike
Brand: Cervelo

Wind tunnel hours and World Tour racing shaped the Cervelo P5 into a benchmark time trial machine. Where the P5 optimizes for a single position held at maximum effort, the P-Series accommodates the realities of racing that includes a run off the bike and the fueling demands of covering long distances.

The carbon frame shares tube profiles with its flagship sibling, achieving a claimed 5.9-gram drag reduction over the previous generation. Paired with Reserve 40|44 wheels and 29mm Vittoria Corsa N.EXT tires, the aerodynamic package delivers a claimed 3.5-watt savings compared to the prior wheel and tire combination. Increased tire clearance across the frame and fork opens the door to wider rubber without compromising the clean airflow Cervelo engineered into the design. The UCI-legal dimensions ensure the bike remains eligible for draft-legal events while maintaining the aerodynamic profile triathletes expect.

A D-shaped steerer tube with a standard round stem interface separates the P-Series from integrated cockpit systems that lock riders into proprietary components. This architecture accepts the included Profile Design Wing 20C carbon basebar and 52 ASA extensions, but swaps readily to aftermarket options if fit requirements evolve or personal preference changes. The result is a race-ready position out of the box with genuine flexibility for future adjustments, whether working with a fitter or experimenting with positions over time...

Stack adjustment extends to 53mm with included spacers, broadening the fit window for athletes who need a higher front end. The seat tube allows angles from 75 to 79 degrees, covering everything from traditional road-influenced positions to aggressive forward setups. Combined with six frame sizes ranging from 48 to 58, the P-Series accommodates a range of body proportions and fit philosophies that many triathlon bikes struggle to address. Athletes with specific fit requirements often find integrated systems limiting, making the modular approach here particularly relevant.

SRAM's Rival AXS wireless drivetrain handles shifting duties with a 48-tooth aero chainring paired to a 10-30T cassette, providing range suited to varied terrain and pacing strategies. The E1 power meter integrated into the crankset provides single-sided power measurement, delivering training and racing data without adding external pods or sensors. Riderever Triva Carbon AXS brake levers work with SRAM AXS Blip controllers at the bar ends, keeping shift actuation accessible from the aero position while maintaining clean cockpit lines.

Triathlon-specific storage covers nutrition, hydration, and mechanicals across multiple locations. The Smartpak 400 top tube bag holds gels and bars within easy reach during racing efforts, while a rear hydration mount accepts bottles or specialized systems for longer events. New to this generation, internal frame storage carved into the down tube holds a spare tube, compact multi-tool, and CO2 cartridges. The access hatch opens with a flip lock, remaining functional even with a bottle cage mounted above it. A front computer mount positions cycling computers or GPS units in an aerodynamic location without requiring additional hardware.

Reserve wheels use a 40mm front and 44mm rear depth configuration with the brand's 4 Pawl hub system, tubeless-compatible rims, and Center Lock rotor mounting. The moderate depth balances aerodynamic efficiency with crosswind stability, addressing a common concern for triathletes racing exposed courses. Shimano CL700 rotors provide consistent braking through varied conditions, and the Vittoria Corsa N.EXT tires arrive tubeless-ready with a balance of grip, rolling efficiency, and puncture resistance suited to race day demands.
