Product Details

Cervélo S3 Disc Ultegra Di2 '17

How do you improve on the already sublime Cervélo S3 Disc Ultegra? Upgrade it with Di2 electronic shifting and Enve SES 3.4 wheels.

Shimano Ultegra Di2 electric shifting
Di2 electric shifting is perhaps the ultimate 'didn't know how good it was till I got it' bike upgrade you can get.

If you do go for Di2, you'll almost certainly love its unbelievably light push-button action and the smoother shifting it delivers - no front gear trimming required, ever.

Once you've used it for a short while, like 99% of the pro peloton, you'll agree that electronic shifting is an upgrade you'll never regret.

Enve SES 3.4 wheels
Cervélo spec wide, deep, lightweight, aerodynamic Enve wheels to further enhance the Cervélo S3 Disc Ultegra Di2's comfort and speed potential.

Bike Radar Review Verdict
'The three days I spent riding the S3 Disc have left me enamoured with it. The light, lively and sharp ride makes it feel like much more of a great all-rounder than an out-and-out aero bike. It's definitely made my bike wishlist.'

Same as Cervélo S3 Disc Ultegra

Cervélo S-series - the range that defined the aero road bike sector - has taken the next logical step to perfection by now coming hydraulic disc brake equipped.

Freed from the constraints of rim brakes Cervélo's engineers have conceived an all-new disc brake optimised carbon layup, which is more aero, 2 watts faster, 9% stiffer and 40g lighter weight than the equivalent S3 with caliper brakes.

  • An S-series Cervélo aero road bike is measurably faster than an equivalent quality regular road bike while being strong enough to handle the worst cobbled roads.
  • The full carbon frame is optimised to minimise drag and maximise speed without compromising comfort.
  • Classic road geometry (73 degree head and seat tube angles in 54cm size) gives a ride that feels familiar to any road cyclist.
  • Dropped Down Tube - minimising the gap between the down tube and the front wheel helps minimise drag.
  • The airfoil-like curved seat tube shields the rear wheel.
  • Cervélo's Reduced-Friction BB Guide ensure your gear cables enjoy an easy run.
  • Future-Proof Cable Management makes the Cervélo S3 ready for a future Di2 upgrade.
  • Admired for their low profile road bike appropriate look and their all-weather hydraulic performance, Shimano Ultegra flat mount BR-RS805s are fast becoming the gold standard in disc brakes for road bikes.
  • Why you want a bike with high quality hydraulic disc brakes.
  • The FSA SLK chainset boasts hollow carbon crank arms.
  • 12mm thru axles create a stronger, stiffer wheel-to-frame/fork interface to ensure solid, confidence-inspiring steering control and optimal disc brake performance.

'We've taken everything that makes the S3 such an aero class leader and made it stronger, stiffer and ultimately, faster. Cervélo only launches a new bike when significant performance gains have been made, and by integrating our disc-brake technologies into the world championship-winning S3 we have done exactly that. The S3 Disc is stiffer and more aerodynamic than its rim-brake counterpart, while continuing to make the most of the lightweight design rooted in our Project California research facility. All of this translates to superior handling and control, giving you the confidence to pull away from the peloton or put the hurt on a Saturday morning group ride.'
