Proprietary cockpit systems lock you into specific components, but they also eliminate the compromises that come with universal fit. The Cervelo HB14 Carbon Handlebar works exclusively with the V-Stem found on 2023 and newer S5 disc frames, creating a two-piece cockpit where the bar and stem function as an integrated aerodynamic unit. The tradeoff for that frame-specific compatibility is a flat-top profile that routes cables internally, keeps the front end clean, and puts your hands in a position shaped by wind tunnel testing rather than manufacturing convenience.

The bar uses a two-bolt interface that clamps into the V-Stem with infinite tilt adjustment between zero and five degrees. That range lets you fine-tune your hand position without swapping stems or adding spacers. Once you find your angle, the connection stays solid—no rotation under load, no creaking at the junction. The flat transition from bar top to hood position keeps your wrists neutral when riding on the hoods, which matters on long days when small ergonomic issues compound into real discomfort.

Geometry sits in compact territory with 80mm of reach and 128mm of drop. That combination works for riders who want a relatively short reach to the hoods but still need enough drop for an aggressive position in the drops. If you're coming from a traditional round bar, the flat-top section feels different under your palms, but the drops themselves follow conventional shaping.... Read More
