Back to Basics, Built for Performance - Meet the all new RIRA All-Road Racing Chassis
In a world where every new bike launch is accompanied by lofty claims of “fastest bike in the world” or “save X watts over a 40km/hr solo ride” etc. it would be easy to forget that cycling is about the senses, the beauty of suffering up a massive col, then dipping into a valley with the surroundings flashing by as if you’re travelling through time.
Chapter2's newest frame, the RIRA is all about the “touchy, feely” side of cycling. Whilst the svelte weight and the carefully dialled stiffness to weight ratio matters to our product team who geek out over Toray T1100 grade specifications, fibre orientation and watts saved etc., it’s what we deliver to your soul that matters to us most.
With the RIRA, we got back to basics. A razor-sharp focus on balance and agility that is sure to raise your pulse, and if that wasn’t enough, it has the looks that will certainly turn a few heads when you rock up to your local bunchie or put the power down to capture your PB.
