Chapter2 RIRA Complete Bike – Precision Performance, Inspired by the Ride
The Chapter2 RIRA Complete Bike with Shimano 105 Di2 is designed for riders who want cutting-edge technology, race-inspired performance, and exceptional ride quality—all in a refined, accessible package. With its lightweight Toray carbon frame, race-tuned geometry, and electronic shifting, this build provides an effortless and exhilarating ride experience, whether you’re pushing the pace in a group ride, tackling long climbs, or sprinting for the line.
Race-Tuned Carbon Engineering
The RIRA’s frame and fork, made from 100% Toray carbon fiber in Japan, are engineered to deliver explosive power transfer, aerodynamic efficiency, and agile handling. With a T47 ceramic bottom bracket, every watt of effort is maximized for smooth, efficient power delivery. The fully integrated MANA5 cockpit ensures a clean, cable-free setup, reducing drag and enhancing aesthetics, while the TUMU carbon seatpost and TCP 3D-printed carbon saddle provide comfort without sacrificing performance.
Shimano 105 Di2 – Proven Performance, Now Wireless
This build features Shimano’s latest 105 Di2 12-speed groupset, bringing precise, wireless electronic shifting to a wider range of riders. The 50/34 compact crankset paired with an 11-34T cassette offers versatility for climbing, sprinting, and all-day endurance riding. The Shimano 105 hydraulic disc brakes provide powerful, consistent braking performance, ensuring confidence-inspiring control in all conditions.
UNAAS HARD2 Carbon Wheels – Aero Meets Stability
Paired with the UNAAS HARD2 50mm carbon wheelset, the RIRA’s aerodynamic efficiency is taken to the next level. These wheels offer the perfect blend of stiffness, lightweight acceleration, and crosswind stability, making them ideal for fast-paced road rides and competitive efforts. Wrapped in Goodyear Eagle F1 tires (700x28c or 700x30c, available in black or tan wall), this setup delivers optimal grip, low rolling resistance, and a smooth ride quality across varied road surfaces.
Whether you’re looking to upgrade to electronic shifting, improve your race-day setup, or simply enjoy an all-around high-performance road bike, the RIRA Complete Bike with Shimano 105 Di2 delivers an unbeatable balance of technology, speed, and value.
