Aerodynamic Alloy Road Bike Stem with Integrated Spacers and 31.8mm Clamp
The Roval Rapide Stem brings aerodynamic performance, precise handling and fit flexibility to a versatile two-piece road bike cockpit.
Inspired by the Roval Rapide Cockpit, this premium alloy stem combines a streamlined shape, integrated spacer design and a 6° angle to help reduce aerodynamic drag while retaining the adjustability of a conventional separate handlebar and stem setup.
Its 3D-forged and CNC-machined alloy construction provides the stiffness required for efficient power transfer and accurate steering, while a traditional 31.8mm handlebar clamp makes it compatible with a broad range of road handlebars.
Available in seven lengths from 70mm to 130mm, the Roval Rapide Stem makes it easy to fine-tune reach and riding position while integrating cleanly with compatible Specialized bikes.
Inspired by the Roval Rapide Cockpit
The Roval Rapide Stem takes design cues from the fully integrated Rapide Cockpit while offering the flexibility of a two-piece system.
This makes it an excellent choice for riders who want a clean, aerodynamic front end without committing to a one-piece bar and stem.
The separate configuration also makes it easier to change handlebar width, stem length or cockpit position as fit requirements evolve.
Aerodynamic Road Bike Design
The stem’s shape has been developed with aerodynamic performance in mind. Its streamlined profile and integrated spacer interface help create a cleaner transition between the stem, headset and handlebar area, reducing unnecessary frontal clutter.
For riders focused on road racing, fast training and performance riding, the design offers a practical way to gain aero benefits while keeping conventional cockpit adjustability.
3D-Forged and CNC-Machined Alloy Construction
The Roval Rapide Stem is manufactured using a combination of 3D forging and CNC machining. This construction process creates a strong and rigid stem designed to deliver precise steering and efficient transfer of rider input through the cockpit. The alloy body provides a balance of stiffness, durability and manageable weight for high-performance road use.
Seven Length Options
The stem is available in a wide range of lengths:
- 70mm
- 80mm
- 90mm
- 100mm
- 110mm
- 120mm
- 130mm
This broad size range makes it easier to achieve the correct reach and riding position for different rider proportions, frame sizes and fit preferences.
6° Stem Angle
A 6° angle provides a performance-focused cockpit position while maintaining flexibility for fit adjustment. Depending on installation orientation and headset configuration, the angle can help riders achieve a lower or more neutral handlebar position.
Traditional 31.8mm Handlebar Clamp
The stem uses a standard 31.8mm handlebar clamp diameter, making it compatible with many modern road bike handlebars.
This is particularly useful for riders who want the aero styling of the Rapide system while keeping the freedom to choose a separate compatible handlebar.
40mm Clamp Height
The stem features a 40mm clamp height, providing a secure interface around the steerer while contributing to the clean proportions of the cockpit.
1-1/8" Steerer Compatibility
The Roval Rapide Stem is designed for a standard 1-1/8" / 28.6mm steerer tube.
Always confirm your fork steerer diameter and headset setup before installation.
Integrated Spacer Compatibility
The stem is designed to work with integrated spacers for a smooth transition into compatible Specialized frames and headset systems. This gives the cockpit a clean, factory-style appearance while retaining the practicality of a separate stem and handlebar.
Optional Integrated Computer Mount
An optional integrated face-plate computer mount is available separately.
Compatible mount SKU: S219900020
This allows a cycling computer to be positioned neatly in front of the stem, reducing cockpit clutter and creating a clean, performance-focused setup.
Rapide Cockpit Top Cap Compatibility
The Roval Rapide Stem is designed for use with the Rapide Cockpit Top Cap and Bolt.
Compatible SKU: S222500008
Using the correct top cap and hardware helps maintain the intended cockpit integration and finish.
Lightweight Performance
The 100mm stem weighs 192g on its own. Total system weight is listed at 212g including the top cap and cable bat assemblies. This makes the Rapide Stem a relatively lightweight option for riders wanting a premium alloy cockpit with integrated aerodynamic features.
