This realizes a delicate and controllable rear brake system.\u003c\/p\u003e\n\n\u003cp\u003eSpecifications\n\u003cbr\u003eMounting Pitch \/ Bolt Size: 40 or 49mm \/ M6 (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\u003eFluid Nipple (included): φ6, φ7.3 (90°)\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.
