ALL-ROAD PERFORMANCE
The Strattos is built for chip-seal, patched pavement, and imperfect roads, delivering the feel of a true road bike with added comfort. Its carbon frame helps smooth out road vibration while keeping pedaling efficient, making it ideal for building confidence and enjoying longer rides beyond perfectly smooth tarmac.
SPORT-ORIENTED GEOMETRY
Endurance-focused geometry and balanced tube shaping create a stable, reassuring ride. The bike handles predictably through corners and stays composed on uneven pavement, giving newer riders confident control and a natural, connected feel on every ride.
MODERN ROAD DESIGN
Clearance for 34mm tires adds versatility beyond smooth pavement, improving grip and comfort on rougher roads. Internal routing keeps the frame clean and tidy, while a traditional cockpit makes adjustments simple and maintenance straightforward for everyday riding and training.
