The MILLENNIUM 4 CARBON COMPOSITE SOLE is made of nylon injected with carbon fiber, providing greater stiffness compared to a standard nylon sole.
MILLENNIUM 4 CARBON COMPOSITE is durable, does not absorb water and is mechanically stable, meaning it is less prone to stiffness variations caused by prolonged use, aging, and changes in temperature or humidity.
MILLENNIUM 4 CARBON COMPOSITE is compatible with the best pedal systems and includes a lateral and longitudinal alignment scale printed on the sole for cleat positioning.
