Specialized Roval Rapide One Piece Bar Stem Cockpit - 400x100mm

Specialized Roval Rapide One-Piece Cockpit – 400mm x 100mm

Aero. Integrated. Race-Proven.

The Roval Rapide One-Piece Cockpit is the fastest leading edge Specialized has ever made. By eliminating the traditional stem/bar hardware junction, Roval engineers created a single, uninterrupted airfoil shape that saves 4 wattsover the two-piece Rapide bar and Tarmac SL7 stem combination.

At race speeds, 4 watts equals a 32cm advantage in a 250m sprint — the difference between winning and throwing the bike at the line.

AERODYNAMIC ADVANTAGE

• Single airfoil leading edge

• Saves 4 watts vs traditional aero setups

• Optimized for clean-air performance

• Developed in the Win Tunnel and validated at World Tour speeds

Designed for solo breakaways, full-gas sprints, and everything in between.

LIGHT & STIFF

By removing the stem hardware cluster, the Rapide Cockpit is:

• 50g lighter than the two-piece Rapide + SL7 stem combo

• Constructed from Premium High Modulus Carbon Fiber

• Engineered for elite sprint stiffness

• Higher stiffness-to-weight ratio than any previous two-piece Roval system

Weight: 310g (100x420 reference)
(400x100mm model similar weight class)

FIT WITHOUT COMPROMISE

One-piece systems traditionally limit fit — not here.

• Designed alongside Retül fit experts

• 15 size combinations available

• Sculpted tops-to-drops radius for wrist clearance

• 4° flare for control and sprint leverage
