Know before you buy
The Kaius 01 is engineered specifically for high-speed gravel racing. It excels on hard-packed dirt, fire roads, and light gravel where efficiency and aerodynamics are prioritized over technical, rugged mountain biking.
While it maintains a performance-oriented, aggressive position similar to a road bike, the Kaius 01 features a longer wheelbase and slacker head tube angle. These adjustments provide the stability and predictable handling required for loose surfaces at high speeds.
The Kaius 01 is built as a race machine, focusing on weight savings and stiffness rather than utility. It lacks the extensive mounting points for racks and heavy luggage found on dedicated adventure or touring gravel bikes.
Yes, the carbon layup and frame geometry are tuned to dampen high-frequency vibrations common on gravel roads. While it remains a stiff, responsive race bike, it is designed to reduce rider fatigue over long, bumpy efforts.
The frame is optimized for modern gravel tire widths, typically accommodating up to 44mm tires. This clearance allows you to balance rolling speed with the extra grip needed for looser or more technical gravel sections.
