Chapter2 Unveils the 695g Rira Ultra Racing Frameset
Chapter2 launches the Rira Ultra, a limited-edition racing frameset weighing just 695g. Built from Toray carbon, it's optimized for pure speed and electronics.
Chapter2 is pushing the boundaries of lightweight performance with its new flagship racing frameset, the Rira Ultra. Engineered for riders who demand uncompromising speed and efficiency, the frameset tips the scales at a startling 695g for a size medium. This featherweight classification is achieved through a meticulous construction process involving over 300 individual layers of precision-placed Toray carbon, creating what Chapter2 describes as a "razor-sharp chassis that delivers blistering responsiveness and race-winning performance."
Designed exclusively for modern electronic groupsets, the Rira Ultra is built for compatibility and versatility. It features a wide-ranging EVO386 bottom bracket platform and generous tire clearance for 34mm front and 32mm rear rubber, making it as capable on rough roads as it is on pristine tarmac. Available in a limited-edition UD Carbon and Gold colorway, each frameset includes both SRAM UDH and Shimano Direct-Mount hangers. With competitive pricing starting at $3,449 including U.S. shipping and taxes, this exclusive frameset offers a potent combination of elite performance and striking aesthetics.
