ENDURANCE REDEFINED
Ride farther, smoother, and stronger with the Strattos C, a Premium Endurance road bike built for long days over chip-seal, patched asphalt, and mixed surfaces. Its ACX carbon frame absorbs road vibration while maintaining lively, responsive pedaling, keeping you fresher for longer rides and confident under acceleration, climbs, and wheel-to-wheel efforts.
RIDER-CENTRIC DESIGN
Endurance-focused geometry balances comfort, stability, and speed. The chassis stays composed on uneven roads, with precise steering through corners. At pace or under load, the bike feels planted and predictable, delivering control, confidence, and engagement on descents, rolling terrain, and sustained efforts.
ALL-ROAD MASTERY
Up to 34 mm tire clearance and tubeless-ready carbon wheels extend your riding beyond smooth pavement. Wider tires at lower pressures boost grip and reduce fatigue, while clean internal routing and an integrated cockpit provide a smooth, distraction-free setup for long rides, mixed-surface training, and year-round cycling.
