The upper body combines technopolymer with carbon fibre reinforcement — stiff enough to hold alignment under load, light enough to sit at 181g on the scale. Ceramic bearings in the bottom pulley reduce friction where it matters most, keeping the drivetrain turning efficiently across all 12 speeds.\u003c\/p\u003e\n\n\u003cp\u003eThe 3D Embrace geometry is designed to keep the chain in optimal contact with smaller-diameter 12-speed sprockets, maintaining traction and reducing the kind of chain slap or hesitation that shows up under hard accelerations. With a medium cage and 37-tooth total capacity, it handles cassettes up to 11-32t — enough range for most road and sportive riding without compromising the tight, responsive feel the Super Record line is known for.\u003c\/p\u003e\n\n\u003ch3\u003eCampagnolo Super Record 12s Rear Derailleur Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 181g\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterials:\u003c\/strong\u003e Technopolymer body with carbon fibre reinforcement, ceramic bottom pulley bearings\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCage Length:\u003c\/strong\u003e Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTotal Capacity:\u003c\/strong\u003e 37t\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Cassette Range:\u003c\/strong\u003e 11-29t, 11-32t\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Campagnolo","offers":[{"title":"Default Title","offer_id":43705737281580,"sku":"RD20-SR124","price":539.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/campagnolo-super-record-12s-rear-derailleur-9359880.jpg?v=1771301891","url":"https:\/\/ricycles.com\/products\/campagnolo-super-record-12s-rear-derailleur","provider":"RA Cycles","version":"1.0","type":"link"}
