The genuine one-piece carbon bar/stem built for Cervélo's S5 — an integrated aero cockpit with internal cable routing, in a 130mm stem and 38/42cm width.

Overview

The HB19 is the factory one-piece handlebar and stem for Cervélo's S5 aero road bike, moulded as a single carbon unit rather than a separate bar clamped to a stem. Integrating the two removes a clamp interface and lets the cockpit be shaped around aerodynamics and clean internal cable routing, which is exactly what the S5's front end is designed around.

It uses Cervélo's "Plus-Four" concept: the bar is 4cm narrower at the hoods than at the drops — here 38cm at the hoods and 42cm at the drops. That keeps your hands, and so your body position, narrower and more aerodynamic on the hoods, while the wider drops give stability for descending and sprinting. All sizes are UCI-legal. This version has a 130mm stem, a 75mm reach, a 125mm drop and a 7° flare in the drops.

Why You'll Like It

Genuine Cervélo one-piece design
The same integrated carbon bar/stem the S5 was engineered around, rather than an approximation from a third party.

Plus-Four aero geometry
Narrower hoods for an aero position on the tops, wider drops for control and stability at speed.

Clean internal cable routing
Built to carry brake and shifting lines internally for the tidy front end an aero road bike needs, and it's Di2 compatible.

UCI-legal
All HB19 size combinations comply with current UCI regulations, so it's fine for racing.

Who Is It For?

This suits owners of a Cervélo S5 who need to replace or change their cockpit — after a crash, to adjust reach with a longer stem, or to change bar width. It is specifically for the S5; it is not a universal handlebar.

Good to Know

Compatibility is specific to the S5. Cervélo lists it for the current S5 generation and retailers report it is also backward compatible with the previous S5 — have your BOTS mechanic confirm your exact frame year before ordering. Cervélo's supporting hardware — a computer/light mount (MT-LM-F-887), titanium mounting hardware (SK-HB19) and bolt covers (GR-HB19) — is listed as separate items, so confirm what you need. An integrated cockpit needs careful installation and cable routing, so have your BOTS mechanic handle the fit.
