The Story
Chapter2 RIRA ULTRA Complete Bike – High Performance Racing Bike
The Chapter2 RIRA Ultra Complete Bike with SRAM FORCE E1 AXS is a race-ready machine designed for pure speed, effortless shifting, and precise handling. Whether you’re tackling a fast-paced criterium, a long endurance ride, or an all-out attack on a climb, this build delivers the perfect balance of aerodynamics, stiffness, and comfort to maximize your performance.
The frameset weighing just 695g (Size M ±3%), the Ultra is meticulously crafted from over 300 layers of precision-placed Toray carbon in custom molds. The result? A razor‑sharp chassis that delivers blistering responsiveness and race-winning performance.
Precision Carbon Engineering for Ultimate Efficiency
Built from 100% Toray carbon fiber in Japan, the RIRA Ultra frame and fork are engineered to provide explosive power transfer, optimal aerodynamics, and responsive handling. The fully integrated MANA5 handlebar and stem create a sleek, cable-free cockpit, optimizing airflow while allowing for customized width and length options. Paired with the TUMU carbon seatpost and TCP 3D-printed carbon saddle, the RIRA ensures long-distance comfort while maintaining an aggressive race posture.
Shimano Ultegra Di2 – Pro-Level Performance Without Compromise
The SRAM FORCE AXS 12-speed groupset brings lightning-fast, wireless shifting and top-tier braking performance, making this build a true high-performance race machine. Choose your preferred crank and cassette gear ratios to suit your personal preferences ( 46/33, 48/35, or 50/34 Crankset + 10-28, 10-30, 10-33, or 10-36 Cassette).
Winspace HYPER LIGHT Carbon Wheels – Aero Meets Stability
To maximize speed and efficiency, the RIRA Ultra Complete Bike is equipped with the Winspace HYPER LIGHT carbon wheelset, the lightest in the Winspace range weighing only 1250g. With optimised rim depths 46mm front and 55mm rear delivering the perfect balance of lightweight acceleration, stability and aerodynamic performance. Wrapped in Goodyear Eagle F1 R tires (700x28c or 700x30c, available in black or tan wall), this setup ensures low rolling resistance, exceptional grip, and a smooth, confident ride across all road conditions.
Whether you’re a seasoned racer, an ambitious Gran Fondo rider, or simply someone looking for an ultra-refined road machine, the RIRA Ultra is built to elevate your ride and deliver top-tier performance every time you hit the road.
