extender is equipped with 4 sliding sliders. You can easily adjust the branches of the elastic rope by moving the buckle so that it covers the curvature of the helmet and luggage. Each strap is composed of 4 small straps, and you can freely adjust the interval of the 4 small tension straps to better cover the object. And the four branches can firmly fix objects in different directions. The hardened steel hook surface is wrapped with a thick plastic shell, which can protect your motorcycle or bicycle from scratches. The tension belt is made of high-quality nylon, which has good elasticity and flexibility, and is not easy to deform and break. For daily use or long-distance travel, you can tie your luggage strap directly to a bicycle or motorcycle, or you can put it in a backpack without taking up any space. 1.
