{"product_id":"ospw-for-campagnolo-12-speed-eps","title":"OSPW for Campagnolo 12-speed EPS","description":"\u003cp data-path-to-node=\"3\"\u003eThe OSPW system for Campagnolo 12-speed EPS is a precision-engineered drivetrain upgrade that replaces the standard derailleur cage and pulleys with a custom-molded carbon fiber cage and significantly larger pulley wheels. By utilizing a 13-tooth upper and 19-tooth lower pulley setup, it reduces the chain's articulation angle, which directly lowers friction and chain drag. This system is designed specifically for the unique geometry and high-precision shifting of the Super Record EPS 12-speed series. Handbuilt in Denmark, it offers a measurable performance advantage, saving approximately 2-3 watts over a stock configuration while providing a service life 3–5 times longer than standard pulleys.\u003c\/p\u003e\n\u003cp data-path-to-node=\"4\"\u003eKey Features\u003c\/p\u003e\n\u003cul data-path-to-node=\"5\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"5,0,0\"\u003eMassive Friction Reduction: Reduces overall drivetrain friction by 35-40% compared to the stock Campagnolo pulley configuration.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"5,1,0\"\u003eCustom Carbon Fiber Cage: Features a compact, lightweight, and durable molded carbon fiber cage engineered specifically for electronic shifting precision.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"5,2,0\"\u003e3 Spring Tension Settings: Allows riders to customize their setup; use high tension for crisp shifting in rough conditions or low tension to maximize raw watt savings.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"5,3,0\"\u003eHandbuilt Ceramic Bearings: Equipped with high-grade silicon nitride balls that are significantly harder and smoother than traditional steel alternatives.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"5,4,0\"\u003eEPS Optimized Geometry: Unlike mechanical versions, this system is tuned to the specific motor torque and movement patterns of the Campagnolo 12-speed EPS rear derailleur.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-path-to-node=\"6\"\u003eSpecifications\u003c\/p\u003e\n\u003cul data-path-to-node=\"7\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"7,0,0\"\u003eCompatibility: Campagnolo Super Record EPS (12-speed electronic only).\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"7,1,0\"\u003ePulley Sizes: 13-tooth upper and 19-tooth lower.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"7,2,0\"\u003eMax Cassette Size: Compatible with cassettes from 11T to 34T.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"7,3,0\"\u003eCage Material: Polyamide-reinforced carbon fiber.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"7,4,0\"\u003ePulley Material: Lightweight Aluminum.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"7,5,0\"\u003eConstraint: NOT compatible with Campagnolo 12-speed mechanical or 12-speed Wireless groupsets.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-path-to-node=\"8\"\u003eTypical Components Included\u003c\/p\u003e\n\u003cul data-path-to-node=\"9\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"9,0,0\"\u003eComplete OSPW System (Cage and 13T\/19T Pulley Wheels).\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"9,1,0\"\u003eCeramicSpeed Bearing Oil (15ml dropper bottle).\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"9,2,0\"\u003eUser manual and installation guide.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"9,3,0\"\u003eCeramicSpeed sticker sheet.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Ceramic Speed","offers":[{"title":"Black \/ Standard Ceramic","offer_id":54269555474804,"sku":null,"price":68440.0,"currency_code":"INR","in_stock":true},{"title":"Black \/ Coated Ceramic","offer_id":54269555507572,"sku":null,"price":68440.0,"currency_code":"INR","in_stock":true},{"title":"Red \/ Standard Ceramic","offer_id":54269555540340,"sku":null,"price":68440.0,"currency_code":"INR","in_stock":true},{"title":"Red \/ Coated Ceramic","offer_id":54269555573108,"sku":null,"price":68440.0,"currency_code":"INR","in_stock":true},{"title":"Blue \/ Standard Ceramic","offer_id":54269555605876,"sku":null,"price":68440.0,"currency_code":"INR","in_stock":true},{"title":"Blue \/ Coated Ceramic","offer_id":54269555638644,"sku":null,"price":68440.0,"currency_code":"INR","in_stock":true},{"title":"Gold \/ Standard Ceramic","offer_id":54269555671412,"sku":null,"price":68440.0,"currency_code":"INR","in_stock":true},{"title":"Gold \/ Coated Ceramic","offer_id":54269555704180,"sku":null,"price":68440.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0986\/1991\/6660\/files\/107426_107428.webp?v=1775153675","url":"https:\/\/velorays.com\/products\/ospw-for-campagnolo-12-speed-eps","provider":"Velorays","version":"1.0","type":"link"}
