This caliper assembly, compatible with 2017 and newer models, features a 2-piston design, which is sufficient for the majority of trail riding situations, providing a good balance between braking power and modulation. The caliper body is forged from aluminum, a manufacturing process that ensures strength and durability while maintaining a light weight. Stainless steel hardware is used to resist corrosion and ensure long-term reliability.

Designed to be mounted on a post mount interface, the caliper can be attached directly to the frame or fork's posts, which is a standard setup for many modern bikes.

Hydraulic lever actuation is employed to activate the braking mechanism, using DOT fluid as the hydraulic medium. DOT fluid is selected for its consistent performance across varying temperatures and its high boiling point, reducing the risk of brake fade during prolonged use.
