HB18 Carbon Handlebar & Stem—stiffer, lighter, and 2 watts more aerodynamic
What Our Gearhead® Experts Are Saying:
"The HB18 is a noticeable upgrade if you care about handling precision and aero efficiency. The integration is seamless with newer Cervélo frames, and it maintains excellent comfort despite the stiffness. Every watt matters on a climb or sprint, and this cockpit gives you a measurable edge."
Engineered for the purest connection between rider and machine, the Cervélo HB18 Carbon 1-Piece Handlebar & Stem sets a new standard for lightweight integration. By leveraging the aerodynamic insights gained from the S5 platform, Cervélo refined the HB18 to save two watts of drag and cut nearly 150 grams of system weight compared to its predecessor—giving racers tangible performance gains on both climbs and flats.
The monocoque carbon structure maximizes torsional stiffness for responsive sprinting and confident cornering, while strategic layup zones preserve compliance over rough tarmac. Cervélo’s integrated design ensures seamless cable routing and a streamlined front profile for minimal wind resistance.
