According to CeramicSpeed, an OSPW system reduces friction by 35-40% compared to stock pulleys, with measurable watt savings on every ride.\u003c\/p\u003e\u003ch3\u003eCustomisable colours and logos\u003c\/h3\u003e\u003cp\u003eThe new design isn't just about looks: the cage has been \u003cstrong\u003ereinforced\u003c\/strong\u003e for greater strength and durability. The RS series lets you choose between different pulleys and logos, and ALPHA versions use patented ADR technology, with a dust cover anchored in the pulley that makes it almost impossible for dirt to enter the bearing.\u003c\/p\u003e\u003ch3\u003eTechnical specifications\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003cstrong\u003eSeries\u003c\/strong\u003e: OSPW RS.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eType\u003c\/strong\u003e: oversized pulley wheel system.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eCage\u003c\/strong\u003e: redesigned and reinforced.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eBearings\u003c\/strong\u003e: CeramicSpeed ceramic.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eCustomisation\u003c\/strong\u003e: different pulleys and logos.\u003c\/li\u003e\u003cli\u003eCompatibility: Shimano 7150.\u003c\/li\u003e\u003cli\u003eWeight: 285 g.\u003c\/li\u003e\u003cli\u003eColour: black.\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently asked questions\u003c\/h3\u003e\u003ch4\u003eWhat's the difference between RS 5-Spoke and RS ALPHA?\u003c\/h4\u003e\u003cp\u003eThe pulleys differ: RS ALPHA uses discs with ADR technology, which completely encloses the bearing against dirt, while the 5-Spoke has the classic five-spoke design.\u003c\/p\u003e\u003ch4\u003eIs it compatible with my derailleur?\u003c\/h4\u003e\u003cp\u003eEach system is designed for the groupsets indicated in the name.
