A rouleur is a rider that performs well on level roads and hills. They excel in breakaways and provide support by maintaining a consistent speed.
Rouleurs excel at riding long and have a smooth pedaling style that allows them to maintain a constant speed over long periods of time. They are not particularly good at hill climbing or sprinting but are versatile and excellent team players—they can chase down breakaways, protect their team leaders from the wind, and assist on stages with varying terrain. Famous rouleurs tend to win stages in major tours and minor tours, employing their craft to maintain high speeds and capitalize on breakaway opportunities.
