The S5 is a sport-wide benchmark for speed and aerodynamic efficiency—with the race results to back it up. From Wout van Aert winning the Green Jersey by the biggest margin of victory in modern history, to Simon Yates riding himself into the maglia rosa, S5’s iconic V-stem and bayonet fork are a fixture at the front of the professional peloton. The new S5 builds on that legacy of speed by getting even faster.Specifications: Fork - Cervélo All-Carbon, Bayonet S5 Fork 1-piece Handlebar/Stem - Cervélo HB19 Carbon Handlebar Sizing - Size 48 - 36cm, Size 51 - 38cm, Size 54 - 40cm, Size 56 - 40cm, Size 58 - 40cm, Size 61 - 40cm Stem Sizing - Size 48 - 80mm, Size 51 - 90mm, Size 54 - 100mm, Size 56 - 100mm, Size 58 - 110mm, Size 61 - 120mm Seatpost - Cervélo SP34 Carbon Seatpost Sizing - Size 48 - 0mm, Size 51 - 0mm, Size 54 - 0mm, Size 56 - 0mm, Size 58 - 15mm, Size 61 - 15mm Headset - FSA SL IS2 1-1/8, 36° x 45° / 1-3/8, 36° x 45° Front Thru Axle - Cervélo Aero Thru Axle Front, M12x1.5mm, 122mm length Rear Thru Axle - Cervélo Aero Thru Axle Rear, M12x1.0mm, 169mm length Accessories - Cervélo Front Computer/Accessory Mount 887, Cervélo Rear Accessory Mount *Specifications are subject to change without notice
