Chapter2 RIRA - Shimano Ultegra Di2 - Performance Road Bike
Chapter2 RIRA Complete Bike – Precision Performance, Inspired by the Ride
The Chapter2 RIRA Complete Bike with Shimano Ultegra Di2 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.
Precision Carbon Engineering for Ultimate Efficiency
Built from 100% Toray carbon fiber in Japan, the RIRA frame and fork are engineered to provide explosive power transfer, optimal aerodynamics, and responsive handling. The T47 ceramic bottom bracket enhances efficiency, ensuring that every watt of effort translates to smooth, powerful movement. 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 Shimano Ultegra Di2 12-speed groupset brings lightning-fast, wireless shifting and top-tier braking performance, making this build a true high-performance race machine. With compact (50/34) and mid-compact (52/36) crankset options paired with 11-30T or 11-34T cassettes, riders get the versatility to power through flats, attack climbs, and maintain control on technical descents. The Shimano Ultegra hydraulic disc brakes with CL800 rotors (140mm or 160mm) ensure consistent, powerful stopping power in all conditions.
UNAAS HARD2 Carbon Wheels – Aero Meets Stability
To maximize speed and efficiency, the RIRA Complete Bike is equipped with the UNAAS HARD2 50mm carbon wheelset, delivering the perfect balance of lightweight acceleration, aerodynamic performance, and stability in crosswinds. 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 Complete Bike with Shimano Ultegra Di2 is built to elevate your ride and deliver top-tier performance every time you hit the road.
