Wheel rim arc design does not hurt the wheel, improves braking, and effectively prevents the damage of sand to the wheel during braking.
When installing, please note that the brake pads should be installed as close to the friction position of the inner part of the steel ring as possible, so make sure to adjust it several times before attaching it! This model is a silent brake pad. If there is sound after installation, please adjust the position and angle again to fix it.
