For cross country riding this is your best choice and is a British made organic pad compound that will not damage your discs. The pads have a medium lifetime and most types are supplied with slightly beefed up retraction springs to prevent pad drag. For downhill racing or longer life in wet and mud see either the RED or GOLD grades.
Most powerful braking of any pad material
Massive lifetime pad for hardened discs only
Sintered copper construction
Great for long life cross country use
Not recommended for downhill racing
These USA made sintered copper pads will last longer and brake stronger than anything you can buy. Do NOT use these on discs marked RESIN pad as such discs will be UNHARDENED steel and these pads could damage soft materials. Supplied with uprated springs in spring based systems.
