Specialized Roval Rapide One-Piece Cockpit – 420mm 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)
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
