When things get dusty, you're going to want serious braking power. In the Shimano Saint BR-M820 Disc Brake Set, you get that powerful, controlled stopping power you've been looking for. Metal Ice-Tech Pads and an opposed ceramic 4-piston design hone braking power without building up too much heat, while the rigid caliper keeps the weight down. If you need top of the line braking performance for gravity fed shenanigans, these are the real deal.
