Cervelo first dipped their toes into the disc brake road bike market with the launch of the R3 Disc last year, and followed that up with the C-Series range of disc-equipped bikes earlier this year. With the super-light and endurance bases covered, the S3 Disc completes the set.

The Cervelo S3 Disc is said to be 40g lighter than the S3 – revamped in 2013 – and also comes with a claimed eight per cent increase in headtube stiffness and nine per cent improvement in bottom bracket stiffness. Most tellingly, however, Cervelo say the S3 Disc is around two watts faster than the non-disc version thanks to a handful of tweaks across the frame. Disc brakes needn’t come at the cost of aerodynamics, they say.

Cervelo say of the new bike: “We’ve taken everything that makes the S3 such an aero class leader and made it stronger, stiffer and ultimately faster.

“Cervelo only launches a new bike when significant performance gains have been made, and by integrating our disc-brake technologies into the world championship-winning D3 we’ve done exactly that.”

The S3 Disc is expected to come in three specs, with Shimano Ultegra, Shimano Ultegra Di2 or SRAM Red eTap. Pricing and UK availability is to be confirmed.
