Cervelo S3 Disc Ultegra Di2 Road Bike
The Cervelo S3 Disc Ultegra Di2 Road Bike offers aerodynamic performance and a very high spec level. Cervelo has been the market leader for aerodynamics for a while now, just ask the Dimension Data world tour team. This dedication to wind tunnel research and testing has allowed them to produce this bike that cuts through the wind like never before. Airfoil sections help with this, as does the minimalist rear triangle that has been borrowed from the top of the range RCA frameset. These thin stays offer comfort and minimise road buzz.
Combining with the aerodynamic performance of the frameset is the strong and reliable braking power of Shimano's BR-RS805 hydraulic disc brakes. These brakes offer superb stopping power in the both the wet and the dry without adding an enormous burden of weight to the bike as a whole.
Gearing is accounted for with Shimano's Ultegra 6870 11-speed Di2 groupset, which offers reliable and smooth shifting and the snappy feel of electronic shifting.
The legendary wheel builder, ENVE, provide their superb 3.4 SES clincher wheels for a light, stiff and fast rolling speed. ENVE's 26mm rear and 24mm front wheel external width boosts rolling efficiency and cornering traction, ensuring that everything you put into the pedals goes down onto the road.
Features:
- BBright increases system stiffness and reduces frame weight while allowing for a large range of crank compatibility in a modern press fit system.
- Tough, compression moulded dropouts save weight with no sacrifice in strength versus traditional metal dropouts.
- Future-Proof Cable Management ensures your frame is compatible with all current and future derailleur and brake systems.
