Cervélo reveals revolutionary RCA frameset

Groundbreaking hand-made Cervelo RCA frameset merges category-defining light weight with aerodynamic competencies.

Earlier today Cervélo introduced its RCA frameset. The RCA frameset builds on Cervélo's famed R5ca frameset and reduces the frameset weight to a mere 667g for a painted 54 cm frame including small parts. In spite of further reducing the frame weight, Cervélo says optimal frame stiffness is maintained.

The RCA frame adopts aerodynamic Squoval 3 tube shapes from Cervélo's S-series bikes and offers internal cable routing and an integrated power meter magnet, positioned at the correct radius from the crank axis to be sensed by many popular crank-based power meters.

325 Cervelo RCA framesets have been manufactured and they are sold at a price of US$10,000 per frameset.

Commenting on the launch of Cervélo's latest invention, Cervélo co-founder and current CEO Phil White told Roadcycling.com "The RCA showcases the best of Cervélo's knowledge, testing, and industry-leading engineering processes. We are always proud to introduce a new Cervélo, but given its no-holds barred, best-of-the-best nature, launching a new Project California bike is particularly special."

The RCA frameset has been developed in cooperation with Team Garmin-Sharp. Riders from the Garmin-Sharp team have contributed to the engineering process by field testing the RCA frame.

"When I test a new bike, it’s not just about getting up on the pedals or being lightweight, it’s the way that the bike works with your body and responds - the stiffness the bike provides me. The Cervélo Rca certainly makes a big difference in that regard," Team Garmin-Sharp's Ryder Hesjedal said when asked to describe his experience with the new Rca.

Garmin-Sharp's Andrew Talansky said "The nice thing about the Rca is that it is vertically compliant to help smooth out the road, but laterally stiff, very stiff - and that’s what we need in cycling."

In a cross-disciplinary process Cervélo brought together its California and Toronto-based engineering teams to have them develop a best-of-both-worlds frameset, which sports the best possible aerodynamic and structural capabilities. The final RCA design was developed using F1 design and testing tools, allowing Cervélo's engineers to test as many aspects of on-road frame performance as possible.

By applying the 3M Powerlux Composite technology, Cervélo's engineers managed to reduce frame weight without compromising frame strength. The use of Integran/PowerMetal Nanovate in the RCA frameset's fork brought the fork weight down to 300g (uncut steerer) without compromising safety, Cervélo stated.
