When changing the rear caliper to a GALE SPEED or Brembo opposed 2-piston caliper (φ32, φ34), depending on the ratio, the brake pedal stroke may become shorter, making it difficult to control. GALE SPEED rear master cylinders have a piston diameter of φ12 and are designed to match the lever ratio of general racing steps. This realizes a delicate and controllable rear brake system. ■Specifications Type: Mounting pitch 45mm\/Rod end M6 Color: Black Piston size: φ12 Compatible calipers: Piston diameter φ32\/φ34 opposed 2-piston Bolt pitch: P1.00 Fluid tank: Separate type Fluid nipple (included): φ6\/φ7.3 (90°) Return spring (included): Standard\/Hard ■Notes *The image is an illustration.
