With 4x25 mm pistons, the caliper offers 40% more piston surface than a conventional 2-piston caliper with 30 mm pistons. The hydraulic leverage is significantly improved and braking power (with the same lever force) is increased. Another advantage of the 4-piston design is the symmetrical load on the pads, which always lie flat. Pad changes can be done quickly and easily with a retaining pin – a major advantage in racing. Central brake line connection.
Fits the BGM brake caliper bracket for PX, PK, T5 and Cosa.
