Shimano engineers have refined all components and features to provide superior driving pleasure, whether you're sprinting to your destination on the Champs-Élysées or climbing a nearby hill. Optimal balance of stiffness, force, weight and rotational power. The structure of HOLLOWGLIDE transducers reduces weight, but retains power for better power transmission and faster and more accurate shifting. Integrated, waterproof and rechargeable lithium-ion battery. Up to 300+ driving hours depending on ANT + / Bluetooth®LE settings. Double-sided power measurement with an accuracy of ± 1.5%.
