Zoom HB-875E Hydraulic Brake is an upgrade kit for the mechanical disc brake system.

Two-way braking, pushing the cylinder piston to brake the disc at the same time, is more durable than ordinary one-way braking and eliminates the safety hazards caused by wheel locking and deformation.

Are you worried about how to upgrade your mechanical brakes? Hycline Brand is your best choice!

Note: Do not remove the "Red piston block" when installation, otherwise it will cause oil leakage or scrap the oil hydraulic disc.

High-quality material: CNC aluminum alloy body, three-finger brake lever, integrated oil cylinder system. The handlebar diameter is 22 mm / 0.87 in. The rear caliper hose and control lever are separated for easy internal routing.

This brake system comes with a brake automatic power-off sensor and is compatible with 2-pin connectors. When you brake, the power output is automatically cut off, ensuring quick and efficient braking.

Compatible with 160/180mm rotors, IS/PM universal mount adapter (only for e-bike models with calipers mounted on the left side)

When purchasing, please pay attention to whether the length of the hose matches your electric bicycle. The hose has been pre-coated with mineral oil and can be used directly without oiling.
