When replacing the rear caliper with a 2-piston opposing caliper (φ32, φ34) from GALE SPEED, Brembo, etc., depending on the ratio, the brake pedal's stroke width may decrease, making it difficult to control. The Gale Speed rear master cylinder has a piston diameter of φ12 and is designed to match the lever ratio of typical racing steps. This achieves a delicate and controllable rear braking system. ■Specifications Type: Mounting pitch 49mm (4mm offset) \/ Rod end M6 Color: Black Piston size: φ12 Compatible calipers: Piston diameter φ32\/φ34 2-piston opposing Bolt pitch: P1.00 Fluid tank: Separate type Fluid nipple (included): φ6\/φ7.3 (90°) Return spring (included): Standard\/Hard ■Notes *The image is for illustrative purposes only.
