Combining the heart of the world's best road bikes with a flat-bar, urban-friendly form, Sirrus Sport redefines the notion of versatility. A lightweight alloy fork and 27-speed Shimano gearing means lighter weight and greater efficiency over varied terrain.
Super light A1 Premium Aluminum fully-manipulated frame offers a great ride and versatility with rack/fender mounts, and wide tire clearance
Straight alloy-blade fork with fender mounts saves weight and adds durability to manage potholes and rough roads
Sirrus double-wall, machined rims for strength and reliable braking; plus alloy, sealed cassette hub with stainless spokes
Flak Jacket protection and a grooved tread make the Specialized Nimbus tires perfect for city or open road use
Triple crankset for 9-speed drivetrain means wide-range gearing, plus chainguard for peace of mind
Specialized Body Geometry Targa Sport saddle has front/rear bumpers for on and off-road durability and ample padding for comfort
WHAT High-performing, experience-specific drivetrains that evolve through the line.
WHY To create high-quality, durable drivetrains that provide the most efficient, intuitive, and smoothest experience for the rider at each level–with an emphasis on wide gear ranges.
HOW As you move through the Sirrus line, the experience changes: the gears move with you. The base model accommodates all riders with a triple crankset with a wide gear range for easier climbing, while the top end has 2x10 gearing for ultimate performance.
BODY GEOMETRY TARGA GRIPS AND SADDLES
WHAT New Body Geometry ergonomic grips and saddles designed to work perfectly with Sirrus.
WHY To optimize comfort at these key contact points, while increasing efficiency in the fitness riding experience.
HOW Ample padding and patented Body Geometry design assure maximum blood flow to sensitive areas, plus hollow Cr-Mo rails for lightweight support and durability. Targa grips use triple-density rubber
DESIGNED WITH BODY GEOMETRY FIT
WHAT Newly designed, flat bar-specific geometry with lower standover, slacker seat tube angle, and longer reach.
WHY To create the most efficient and comfortable fitness-riding position right out of the box, for a wider range of riders, without major adjustments or swapping components.
HOW Working directly with our Body Geometry Fit professors, we straightened the toptube and made the reach longer. This provides the confidence and stability of a lower standover while allowing the arms and shoulders to loosen in a more ergonomic position on the bars. At the same time we slackened the seat tube to better align the knee over the pedal, increasing efficiency and comfort while pedaling.
FACT 8R CARBON FRAME
WHAT New FACT 8R carbon frame.
WHY To provide a compliant, comfortable bike to riders looking for road bike speed with flat handlebar fit.
HOW Carbon fiber allows engineers to create a lightweight frame with additional compliance, leading to a fast, confident ride.
