New disc brake road bike to come in a range of builds between £4,249 and £7,649

With the UCI expected to restart its disc brake trial in January, Cervelo has launched a disc-equipped version of its highly successful S3 road bike for Dimension Data to ride next season.

Unsurprisingly, the Cervelo S3 Disc is claimed to be better than the rim-brake version in pretty much every way. Most importantly, for fans of aerodynamics, the redesigned fork that has been possible thanks to the loss of the rim brake calipers has meant that the bike will save you two watts over the standard model.

Elsewhere, Cervelo is also saying that its new bike is stiffer than the old model. The head tube and bottom bracket are apparently 8 per cent and 9 per cent stiffer respectively, hopefully improving handling and power transfer, while the frame is also 40g lighter than the rim-brake version.

As you would expect, the new Cervelo S3 comes with thru-axles (12mm front and rear), and flat mount calipers, both of which are steadily becoming the standard for the disc-equipped road market. Not quite as standard is the BBright bottom bracket, a unique feature of Cervelo bikes that the company says helps to improve stiffness.

There will be three different builds to chose from, none of which will be particularly cheap. The least expensive model will be priced at £4,249 with Shimano Ultegra, transitioning through the £6,199 Shimano Ultegra Di2 version, all the way to the top-of-the-line £7,649 SRAM Red eTap model. We’ll have to wait until we have a bike in for test before judging if those price tags give good value for money.
