The 856 uses a belt driven system by Gates which offers a clean, fuss- free, efficient drivetrain.
It provides a very quiet drive experience which also remains very smooth in operation.
A perfect partner to the Bosch e system, carbon reinforced belts last longer than chains, never need grease and are nearly maintenance-free.
Created by Gates Corporation, a global leader in belt drive technologies, Gates Carbon Drive is the best high-mileage bicycle drive on the market.
