Furthermore

The core of this caliper’s performance lies in its advanced technology. Unlike a standard caliper, it features a four-piston, differential-bore design. This means the two pistons leading the brake pad are smaller in diameter than the trailing two. This innovative design ensures that pressure is applied evenly across the entire surface of the brake pad, preventing uneven wear and providing a consistent, linear response at the brake lever. The caliper body is precision-machined from a single block of high-strength billet aluminum, providing an incredibly rigid and flex-free structure that translates to a firm and responsive brake feel. This rigidity also ensures superior heat dissipation, helping to prevent brake fade under hard or prolonged use.
