The adjustment function of the brake handle means that the height, Angle and tension of the brake handle can be fine-tuned according to individual needs and preferences to provide a more comfortable and personalized experience. The following are some common brake adjustment functions:

Height adjustment: Some brake handles are designed to allow the user to adjust their mounting height on the handlebars. By adjusting the screws or the tightening device, the brake bars can be moved up and down relative to the handlebars to suit the hand type and habits of different riders.

Angle adjustment: The brake handle can usually be freely rotated on the horizontal plane to adjust the tilt Angle of the brake handle. By rotating the brake handle, it can be set to a comfortable and easy to operate Angle according to personal preference.

Tension adjustment: Some brake handles are equipped with adjusting screws to adjust the tension of the brake line. By turning the screw, you can increase or decrease the pull of the brake line, thereby adjusting the response and force of the brake. Note that when adjusting brake line tension, it is necessary to ensure that the brake is still fully released.

Distance adjustment: For dual-lever systems (such as road vehicles), it is sometimes possible to adjust the distance between the two levers to suit different hand types or personal preferences. This can be done by loosening and tightening the coupling nut or screw between the brake bars.

It should be noted that when adjusting the brake handle, it should be operated according to the product instructions and follow the principles of safety. If you are not sure how to adjust or encounter difficulties, you can ask professional technicians to assist or consult the customer service of the relevant brand. Properly adjusting the handlebars can provide a better riding experience and safety.
