Handlebar Geometry & Aerodynamics

• Background: While Cervelo has been innovative in frame design, its handlebar geometry remains conservative. Competitors such as the BMC Teammachine R01 have already adopted narrower 360 mm handlebars for aerodynamic benefits.

• Need: Many riders identified during bike fitting sessions require a 360 mm bar, but Cervelo S5 originally did not offer this option, limiting ergonomics.

• Solution: The EXS S5 handlebar provides a 360 mm top width and 400 mm drop width, meeting the latest UCI regulations while balancing aerodynamics and control.

Geometry Consistency & Ergonomics

• Reach & Drop: Maintains the same 80 mm reach and nearly identical drop as the stock S5 handlebar.

• Ease of Replacement: Riders can adapt quickly without needing a new stem, minimizing adjustment time.

• Ergonomic Enhancement: Lower hand positions were refined with ergonomic shaping for improved comfort and grip.

Upper vs. Lower Hand Position Dynamics

• Width Differentiation: Narrower 360 mm top and wider 400 mm drop provide sprint stability and reduce hand interference in aggressive positions.

• Support Optimization: Adjusted upper bar angles improve hand support in low-drag positions.

Weight & Stiffness

• Weight Savings: Compared to the original S5 bar, the EXS version saves ~40 g. When paired with the EXS 3D-printed titanium out-front mount, the advantage extends up to ~65 g.

• Engineering Choice: Tube walls could be further thinned for more savings (1020 g), but stiffness and aerodynamic performance were prioritized over extreme weight reduction.

• Design Philosophy: For the S5, aerodynamics remain the first priority; weight savings are a secondary bonus.

Computer Mount & Modularity

• 3D-Printed Titanium Mount: Allows for stepless fore-aft adjustment of computer positioning.

• User Fit Range: Supports both small and large device setups, ensuring flexibility across rider preferences.
