This realizes a delicate and controllable rear brake system.\u003c\/p\u003e\n\n\u003cp\u003eSpecifications\n\u003cbr\u003eMounting pitch\/bolt size: 45mm (M8→M6 conversion spacer included)\n\u003cbr\u003eRod end: M6\n\u003cbr\u003ePiston size: φ12\n\u003cbr\u003eCompatible calipers: Piston diameter φ32\/φ34 opposed 2-piston\n\u003cbr\u003eBolt pitch: P1.00\n\u003cbr\u003eFluid tank: Separate type\n\u003cbr\u003eReturn spring (included): Standard, hard\n\u003cbr\u003eColor: Black\u003c\/p\u003e\n\n\u003cp\u003e■Notes on images\n\u003cbr\u003e*Images are for illustration purposes only.
