Said to have been four years in development, the CS600 measures time, speed, distance, altitude, inclination and cadence.
The top-end HRM also has a cycling efficiency feature designed to help riders improve their cycling economy by interpreting their efficiency ratio to help improve their performances during long races. Data is transmitted wirelessly.
The optional power sensor measures speed, distance and chain speed, providing information on power output, cycling efficiency, pedalling index and L/R balance.
