Chapter2 RIRA - Shimano Dura-Ace Di2 - Performance Road Bike
Chapter2 RIRA Complete Bike – Precision Performance, Inspired by the Ride
In a world where every new bike launch comes with lofty claims of being the “fastest bike in the world” or “saving X watts over a 40km solo effort,” it’s easy to lose sight of what cycling is really about. The RIRA isn’t just about numbers and aerodynamics—it’s about feeling the ride, the beauty of suffering up a massive climb, and the rush of a fast descent where the world blurs around you.
While the product team obsesses over Toray T1100 carbon layups, weight savings, and stiffness ratios, what matters most is what the RIRA delivers to your soul. Every detail has been designed to create a bike that is as engaging and thrilling to ride as it is technically refined.
With the RIRA Complete Bike, you get a razor-sharp balance of agility and power, tuned for pure exhilaration. Whether you’re lining up for race day, pushing for a PB, or leading the local bunch ride, the RIRA is built to elevate your experience. Its T47 85.5 bottom bracket ensures exceptional stiffness and compatibility with a wide range of cranksets, while the 27.2mm seatpost standard allows for precise fit adjustments and weight tuning. Pair it with the optional Chapter2 TUMU seatpost (219g) for the full Chapter2 ride experience.
This frameset is built exclusively for electronic groupsets, featuring both a SRAM UDH hanger and Shimano Direct Mount hanger for seamless drivetrain compatibility. With tire clearance up to 32mm in the rear and 34mm in the front, the RIRA ensures a smooth yet responsive ride, giving you the perfect blend of comfort, grip, and speed.
Elite-Level Build Kit for Uncompromising Performance
For those who want a race-ready bike straight out of the box, the RIRA Complete Bike delivers world-class components paired with the latest Chapter2 technology.
