Key Benefits for Riders
Lightweight Design for a Faster, Easier Ride
Built with a carbon fiber fork and a premium A1 alloy frame, the Sirrus 4.0 offers a lightweight, responsive ride. The carbon fork reduces weight significantly, saving nearly 3 pounds compared to the Sirrus 2.0 model. This means less weight to carry on your daily rides, allowing for quicker acceleration, better handling, and easier climbing. Whether you're navigating through traffic or tackling your local park paths, the Sirrus 4.0 makes every ride feel effortless.
Comfort and Control for Longer Rides
The Sirrus 4.0 features ergonomically designed Body Geometry touchpoints, including the saddle and grips, which reduce pressure on key areas, ensuring you stay comfortable even on longer rides. The inclusion of the Future Shock 1.5 system offers 20mm of axial compliance, helping to smooth out the ride over rough roads and bumps. This combination of comfort and performance ensures that you can ride longer without discomfort, making it perfect for those pushing toward fitness goals or exploring new routes.
Precise Shifting for All Your Adventures
The wide-range 2x10 MicroSHIFT drivetrain gives you precise and intuitive shifting, allowing you to tackle varying terrain with ease. Whether you're cruising on flat roads or powering through uphill climbs, the Sirrus 4.0 provides smooth transitions between gears, helping you maintain a consistent cadence and optimize your power output. This drivetrain is built to withstand the demands of daily riding, ensuring durability and long-lasting performance.
Powerful Stopping Power in Any Condition
Equipped with Tektro HD-R280 hydraulic disc brakes, the Sirrus 4.0 provides reliable stopping power, whether you're riding in wet, dry, or hilly conditions. The 160mm front and 140mm rear rotors offer exceptional modulation and control, ensuring that you can stop confidently even at high speeds or on slippery surfaces. With these brakes, you can ride with peace of mind knowing you’ll have dependable stopping power in any weather.
Durability That Keeps Up with Your Daily Ride
Crafted from durable A1 SL premium aluminum, the Sirrus 4.0 features fully manipulated butted tubing for strength and longevity. The internal cable routing not only improves aesthetics but also reduces the chances of wear and tear over time.
