Free Chapter 2 Handlebar with Purchase Through Dec 31st
The RIRA Ultra is the flagship road-racing frameset from Chapter2 , engineered for riders who demand the highest level of speed, responsiveness, and precision. Every detail is optimized for race-day performance: from a feather-light chassis to aerodynamic shaping and modern standards, this is a frameset built to win.
Built on the proven RIRA geometry, the Ultra’s aero-tuned shaping and finely crafted carbon layup deliver razor-sharp stiffness, explosive responsiveness, and confident handling , whether you’re sprinting, climbing, or hammering through technical descents.
Despite its race-ready focus, the RIRA Ultra remains practical for real-world riding — it clears up to 34 mm tires front / 32 mm rear, giving you the option to build a bike that’s ready for rough roads, cobbles, or endurance events as easily as a crit race.
