Twin 24mm diameter pistons housed in forged calipers give you excellent braking power in demanding situations. Forged lever bodies and ergonomic 3-finger reach adjustable levers provide excellent control. The pad contact point is self adjusting providing consistent braking force and reliability.
The Aspire does well in downhill situations, where stopping power is a must and not an option. These brakes WILL stop you.
Pads are compatible with Shimano XTR and XT.
