Monobloc Caliper

One block of forged aluminum, six pistons, zero flex. The part every other part is measured against.

Machined from a single forging — never cast, never bolted from halves — so there is nothing to flex, weep, or work loose under heat. Six differential-bore pistons clamp the pad evenly across its full face, killing taper wear and giving a pedal that stays firm from the pit lane to the last lap. Hard-anodized in signature hazard orange and pressure-tested to twice its rated line pressure before it earns the A1 stamp.
