{"product_id":"ospw-rs-alpha-for-shimano-7150","title":"OSPW RS ALPHA for Shimano 7150","description":"\u003cp data-path-to-node=\"3\"\u003eThe OSPW RS ALPHA is a modern, angular evolution of the traditional oversized pulley system. It features a reinforced, injection-molded carbon fiber cage that provides superior stiffness and shifting precision. This system is defined by its ALPHA Disc Pulley Wheels, which use a solid aluminum disc construction. This design eliminates the \"fan effect\" of traditional spokes and prevents road debris or grass from getting caught in the pulleys. It is further enhanced by Active Debris Remover (ADR) technology—a patent-pending system that uses centrifugal force and a unique dust cover to dynamically extract contaminants while you ride.\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\"\u003eALPHA Disc Technology: Solid aluminum disc pulleys increase lateral stiffness for faster, more reliable gear changes and a cleaner aesthetic.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"5,1,0\"\u003eActive Debris Remover (ADR): Integrated bearing protection that flings mud and water away from the bearings, ensuring the system remains \"clog-proof.\"\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"5,2,0\"\u003eFurther Drive Technology: Optimized 13-tooth upper and 19-tooth lower pulley profiles designed specifically for Shimano 12-speed chains to minimize noise.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"5,3,0\"\u003eCustomizable Tension: Features adjustable spring tension settings, allowing riders to prioritize either maximum power savings or high-tension chain security.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"5,4,0\"\u003eLifetime Warranty: Due to the extreme durability of the ALPHA discs and ADR protection, this system comes standard with handbuilt ceramic bearings backed by a lifetime warranty.\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: Shimano 105 Di2 (RD-R7150) 12-speed only.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"7,1,0\"\u003eMax Cassette Size: Supports up to a 36T cassette.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"7,2,0\"\u003ePulley Material: Solid Aluminum with composite tooth profiles.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"7,3,0\"\u003eBearing Type: Coated Ceramic (75% harder races than steel).\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"7,4,0\"\u003eCage Material: Carbon fiber reinforced Polyamide.\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 RS ALPHA System for Shimano 7150.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"9,1,0\"\u003eCeramicSpeed Pulley Oil (15ml).\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"9,2,0\"\u003eCustom Shimano 105 cage installation tool.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"9,3,0\"\u003eB-Gap adjustment tool.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Ceramic Speed","offers":[{"title":"Black \/ Coated Ceramic","offer_id":54272289898868,"sku":null,"price":85550.0,"currency_code":"INR","in_stock":true},{"title":"Silver \/ Coated Ceramic","offer_id":54272289931636,"sku":null,"price":85550.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0986\/1991\/6660\/files\/113496_efcaee99-7a1a-47b5-9c40-aa1f6c03bd5f.webp?v=1775219192","url":"https:\/\/velorays.com\/products\/ospw-rs-alpha-for-shimano-7150","provider":"Velorays","version":"1.0","type":"link"}
