The Cervélo HB18 Carbon One-Piece Handlebar & Stem combines lightweight construction, aerodynamic efficiency and precise handling in a fully integrated cockpit designed for high-performance road cycling.

Engineered for the Cervélo R5, Soloist and compatible Caledonia-5 models, the HB18 features a premium carbon fibre construction that integrates the handlebar and stem into a single streamlined unit. Its clean design supports internal cable routing, reducing aerodynamic drag while maintaining a sleek, professional appearance.

The ergonomic geometry features a compact 75 mm reach and 125 mm drop, providing comfortable hand positions and excellent control. The 7° flared drops offer additional stability and confidence when sprinting, descending or riding aggressively.
