The SRAM Guide/Trail disc brake pads are made for every Guide or Trail brake. Available in 3 different versions. You can pick the brake pads you prefer.
The soft version is also called organic. These brake pads provide the most stopping power but are slightly less durable than the metal version. This is a brake pad for the avid rider who wants to push itself to their limits but still wants to have good control over his bicycle.
The softer version with aluminum backplate ensures the heat gets drained faster. This is a brake pad for the racer who wants the best stopping power and control that is available.
The metal version will last much long, but provides slightly less stopping power than that the organic blocks deliver. This is a brake pad for the average rider who wants control but wants his pads last for a complete season.
