Cyclingnews, February 2023
In its review of the fourth-generation Cannondale SuperSix EVO, Cyclingnews praised the bike’s balance of aerodynamic performance, low weight and predictable handling. The SystemBar R-One formed an important part of the premium build’s streamlined front end. The review found the complete bike exceptionally capable from a pure performance perspective, although the proprietary cockpit arrangement was recognised as less flexible than a conventional handlebar and stem.

Cyclist’s later assessment of the evolving SuperSix EVO platform again highlighted the value of a narrow, ergonomic and fully integrated cockpit in reducing frontal area and cleaning up airflow around the front of the bike. The publication also identified the familiar compromise of integrated systems: excellent aerodynamic presentation and race-focused control, but less straightforward fit adjustment.
Roval Rapide Cockpit
The Roval Rapide Cockpit is lighter, with a claimed weight of approximately 307 g in a 400 x 100 mm configuration, and offers more width, stem-length and flare combinations. Its 75 mm reach and 127 mm drop are slightly more compact than the Cannondale cockpit.
The Roval is an attractive alternative for riders prioritising minimum weight and broader compatibility. However, the Cannondale SystemBar R-One integrates specifically with the Delta Steerer system, giving a compatible SuperSix EVO a more cohesive factory appearance.
Vision Metron 5D ACR EVO
The Vision Metron 5D ACR EVO has an approximate claimed weight of 320 g in a 420 x 110 mm size, with an 80 mm reach, 125 mm drop and -6-degree stem angle. Its 10-degree forward sweep is designed to provide a more open hand and upper-body position.
The Vision offers a wider selection of stem lengths and bar widths and is compatible with Vision’s ACR routing ecosystem. It is a strong cross-shop option for riders building around a conventional 1 1/8-inch ACR-compatible front end. The Cannondale remains the cleaner and more direct choice for a bike designed around the Delta Steerer system.
ENVE SES AR One-Piece Handlebar
The ENVE SES AR cockpit places greater emphasis on all-road versatility. Its pronounced 18-degree flare creates a substantially wider position in the drops, providing additional leverage and stability on broken surfaces and fast descents.
The ENVE is better suited to riders mixing sealed roads with poorly surfaced backroads or light all-road riding. The Cannondale is more narrowly focused on aerodynamic road racing, with less flare and a more dedicated SuperSix EVO integration.
