Chapter 2 RIRA Carbon Disc Frameset - Options

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.

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.

The RIRA sports a T47 85.5 BB Standard that is quickly becoming the default standard for high tolerance and stiffness, as well as offering many BB and Crankset options in the market. By using a standard 27.2mm Seatpost, you can really dial in your bike fit as well as target weight. Of course, you can also choose the optional C2 TUMU Seatpost at 219g to get the full C2 experience.

The RIRA frameset comes with Sram UDH Hanger and Shimano Direct Mount Hnager and is only compatible Electronic Groupsets. The chassis and fork accommodate tires up to 32mm in the rear and 34mm in the front, ensuring a smooth and fast ride, so you will have ample room for high volume tires for the fast and plush ride quality.

FEATURES/BENEFITS

The sleek 950g RIRA Form Factor has all the trademarks of a modern race frameset, such as a T47 85.5 BB for added stiffness and maximum BB/Crankset compatibility. The slender waistline of the headtube carefully manages the airflow to minimise drag, creating a slippery silhouette that delivers

Each frameset comes with a Sram UDH Hanger as well as a Shimano Direct Mount Hanger allow maximum shifting performance with both Gruppo Manufacturers.

In a world of bespoke Seatposts, C2 are bucking the trend by engineering the RIRA specifically for the round 27.2 Seatpost so you can select the best post in the market that suits your needs, including the 219g C2 TUMU 0mm Setback post.
