Description

Installation device for hydraulic brake handle

This work is about the hydraulic brake handles of bicycles, especially the combination of hydraulic brake handles and aerobars.

Bicycles are generally composed of related components such as frame, steering, transmission, braking, and shock absorption. Their use has become a favorite sport of modern people from traditional transportation, and even evolved into various exclusive competitions, such as off-road Cars for racing, downhill/downhill racing, road racing, time trial, triathlon, etc.

The above-mentioned conventional brakes are controlled by conventional brakes and hydraulic brakes using hydraulic systems. The hydraulic brake is an oil pipe connected to the brake handle and the brake caliper. When the brake is applied, only the brake handle can be operated to squeeze the oil into the caliper through the oil pipe, so that the piston of the caliper is pushed down by the oil to push the brake piece, so that Make the clip against the friction disc, slow down the wheel rotation speed or even stop the rotation, and the friction between the tire surface and the ground directly reaches the brake to slow down or stop. Because the oil is not easy to compress and has a good operating feel, it is not affected by the changing climate and muddy water on rough roads. It is currently widely used in various bicycles and the above competitions.

Especially in the bicycles and time trials in the above three races, in order to effectively reduce the air resistance, aerodynamics (Aero bars) are specially installed on the position of the upper tube of the front fork to reduce the rider's upper body posture.
