Superlight frame at 695g, all-road integrated frame up to 34mm tire clearance front and 32mm rear

The RIRA Ultra is our flagship high-performance racing frameset—engineered for riders who demand uncompromising speed, precision, and race-day readiness. Built on our proven RIRA Geometry and fine-tuned for aerodynamics. Every surface, edge, and profile is designed to reduce drag and enhance eﬃciency across all terrains.

Weighing just 695 g (Size M ±3%), the Ultra is meticulously constructed from over 300 layers of high-grade Toray carbon, strategically laid into custom moulds for optimal strength-to-weight ratio. The result is a feather- light chassis that reacts instantly to every watt you put down, delivering blistering responsiveness on climbs, sprints, and technical descents alike.

From the first pedal stroke to the final sprint, the RIRA Ultra brings pro-level performance within reach. Its aggressive-yet-balanced geometry provides nimble handling through corners and confident stability at high speed. Every gram has been shaved without compromising stiﬀness or ride quality, ensuring it feels fast and composed under maximum load. Whether you're attacking the breakaway, chasing a personal best, or hunting podiums, the Ultra is your ultimate weapon.

Aesthetically, the Ultra’s silhouette is clean, sculpted, and undeniably fast—turning heads whether you're leading the pack or out on a solo mission. It’s designed to be as functional as it is beautiful. The EVO386 bottom bracket platform provides compatibility with a broad range of cranksets, and the 27.2 mm seatpost diameter allows riders to fine-tune fit and comfort—or go all-in on weight savings with the 219 g C2 TUMU Seatpost.

Built exclusively for electronic drivetrains, the RIRA Ultra includes both SRAM UDH and Shimano Direct-Mount hangers for seamless setup across groupsets. Tyre clearance of 32 mm at the rear and 34 mm at the front ensures confident handling on rougher roads, cobbles, or broken tarmac—giving you race-level performance in real-world conditions.

The RIRA Ultra isn’t just about being light. It’s about redefining what lightweight can do. Engineered to push boundaries and built to win, it’s the purest expression of speed we’ve ever created.

Might have found my forever bike

Frankly, I was just looking for a solid frame that wouldn't break my budget. So, initially it was price that was the driving factor for my purchase of an origin series Huru. Turns out, Chapter2 North America is located here in my city. So, when I reached out about the frame, I was connected with Clive de Sousa. Not only...

Chapter 2 is incredible

Chapter 2 was incredible to buy a bike from, as their customer service is even better than their incredible bikes. I ordered an XL Kaha after speaking to them directly about its size and to my bike fitter. This was my first frame-up build and I had several questions as I built the bike. They were always quick to respond either via text or email. Absolutely zero complains about the entire process and stoked to now own one of the most unique bikes in my home town.
