Cervelo S3 Ultegra Di2 Road Bike
Perfect for the road rider wanting a high-end and premium performance on the road, the Cervelo S3 Ultegra Di2 Road Bike is a top option for powering to your goals, improving your response and smoothing out the flaws in each and every pedal stroke.
Centered around the quality S3 Frame, this bike uses a high-grade carbon fibre. Shaped into Cervelo's famed Squoval form, this frame delivers improvements in stiffness at the bottom bracket of 16% whilst the entire frame is a full 23% more torsionally stiff than the previous edition. This fact helping you convert your energy input into the task of pushing forwards, this bike is a smooth performer.

Equipped with a Shimano Ultegra Di2 R8050 Groupset, this S3 is sure to deliver a near pro-level response. Electronic shifting making for smooth, blended shifting between front and rear cogs, you needn't ever miss a beat in transmission. With a 52/36T chainset and an 11-28T cassette, this bike is robustly geared for those longer, flatter days, where all that counts is time and speed.
Rolling on Mavic Cosmic Elite Wheels, this bike retains a low weight whilst assuring you of a reliable and robust wheelset. Finished with a Fizik Antares R7 Saddle and with Cervelo specific componentry finishing off this machine, this bike is set to deliver a truly dialled in performance.
