Cervelo S3 Ultegra Carbon Disc Aero Road Bike - 51cm
The suggested rider height is the recommended height range for this size of bike as stated directly from the manufacturer for this specific model - It is the most reliable sizing metric.
However, please note that although these height ranges are recommended by the brand, they may not be accurate for everyone. Factors such as inseam length and preferred riding positions can affect the appropriate sizing.
If you see the label "not confirmed," it means either this brand doesn't provide recommended height ranges, or we were unable to locate it for this model. In these cases you you can refer to our general sizing guide

About this bike
Seller Description:
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.
BBRIGHT
This asymmetrical 79mm bottom-bracket standard yields stiffer and lighter frames and crank systems.
CARBON DROPOUTS
Tough, compression-molded dropouts save weight with no sacrifice in strength compared to traditional metal dropouts.
EVOLVED STEERER DESIGN
The fork steerer’s diameter has a noticeable effect on a bike’s handling. Evolved steerer design applies the diameters and taper designs that best suit each model.
FUTURE-PROOF CABLE MANAGEMENT
Ensures your frame is compatible with all current and future derailleur and brake systems.
PARTIAL SEAT TUBE CUTOUT
A close-fitting curve in the seat-tube’s trailing edge improves aerodynamics by partially shielding the leading edge and top of the rear wheel.
Equipped with Shimano Ultegra gear shifting system. Smoothly slotting your derailleur and chain into place, this component set provides a great balance between durability and efficiency. Swift and smooth and comes with a comprehensive gearing ratio. Disc brake equipped, this bike offers enhanced stopping power, and makes sure that you can edge out an advantage when tackling rolling turns.
Condition
The bike is in good condition but does have a few minor unnoticeable scratches/chips. The groupset works flawlessly, bearings smooth all round and brakes are strong. Everything has lots of life left in it.
