Introduzione

Hello, this guide will be instructing you on how to adjust loose or tight cantilever bike rim brakes. When you’re pedaling, they can rub against your bike and slow you down, therefore requiring more pedaling. In addition, the added wear to your brake will require you to replace your brake pads sooner than you would normally need to causing you to incur unnecessary costs.

Keep in mind that this guide will only help you address brake rub if your rims are straight. If your wheels are out of true, adjusting the brake position will only cause the brake to rub elsewhere, so before beginning this guide, check that your wheels spin straight, without any twists or hops.
