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.
