To Be STRONG in Maori

Introducing our lightest, stiffest and most comfortable race bike. The RIRA embodies Chapter2’s design ethos – a perfect harmony of engineering excellence and an refined cycling experience.

Designed to be a light weight, all round, race machine. Fast around a crit track or up the hills of a Grand Fondo.

To understand the improvements we’ve made when making the RIRA and the RIRA Ultra, we compared it to its predecessor, TOA.

Stiffness tests were conducted on testing equipment to quantify the improvements with a 22% increase in head tube stiffness and a 12% increase in bottom bracket stiffness. Both results are reflected in the ride quality with the RIRA being an ideal race and performance platform.

All in all, the RIRA is more aerodynamic, stiffer, and more comfortable than the TOA.

We are excited to launch the RIRA Ultra as the ultimate racing and climbing bike weighing only 695g. A weight saving achieved through the meticulous placement of over 300 layers of precision-placed Toray Carbon.

The Ultimate Racing Machine

With over 300+ pieces of precision-laid Toray carbon and countless layup iterations, the RIRA Ultra delivers maximum performance with minimum weight – engineered not just to impress on the scales, but to elevate every pedal stroke.

For climbers, sprinters, and racers alike, its aggressive yet-balanced geometry and agile handling elevate every turn into a heart-pounding moment.

The result? A razor‑sharp chassis that delivers blistering responsiveness and race-winning performance.

With a limited number of bikes designed in each colourway you are getting something unique. Dare to be different.
