Features： 1、The surface is treated with CNC anodizing to prolong the service life. Can dissipate heat, reduce noise, high temperature resistance, not easy to decolor. 2、The braking performance of good quality composite rubber is softer, smoother and faster. Even in rain and snow, the braking effect guarantees your safety. 3、Aluminum alloy (brake block shell) + brake rubber (cork mixed material) effectively improve the braking performance, remove the screw to move the shell to replace the brake block. 4、The groove shaped drainage design of the brake block prevents sand, mud and damage to the wheel, and effectively discharges mud and drains under bad weather and road conditions. 5、The brake block is widely applicable, suitable for road bikes with carbon fiber rim material, dead speed bikes, folding bikes, mountain bikes, etc. Specification： Item Type: Bicycle Brake Pads Material: Aluminum Alloy (Brake Block Shell) + Brake Rubber (Cork Mixed Material) Size: Approx. 55x12mm / 2.2x0.5in Process: CNC Anodized Surface Treatment, Not Easy to Decolorize Range of Application: Road Bikes with Carbon Fiber Rim Material, Dead Speed Bikes, Folding Bikes, etc. Package List： 2 x Brake Rubber
