The world's fastest oversized pulley system is also available for SRAM Rival & Force 1 Type 3 derailleurs. Featuring 14-tooth (upper) and 18-tooth (lower) narrow-wide profile pulleys, the OSPW X System for SRAM 1x is available fitted with standard coated CeramicSpeed bearings (4-year warranty) or SLT (lifetime warranty). The exclusive narrow-wide tooth profile of the pulleys ensures lasting chain retention. The system features a strong, custom carbon fiber pulley cage for long life and light weight. The cage design allows you to choose between two spring tension settings to customize performance and reduce chain friction. We recommend the initial setup with the lower spring tension. This is designed to leave the chain retention clutch mechanism fully functional. In case the low spring tension does not provide adequate shifting quality on very rough roads, it can be increased to the high tension setting, which corresponds to factory settings. Thanks to the high-quality CeramicSpeed Bearings inside, your product will benefit from a 3 to 5 times longer lifespan than the standard one. The OSPW X System for SRAM 1x has been tested to offer 30-40% less friction than conventional systems. Together with the ultra-high quality CeramicSpeed bearings inside, the product is fully developed and hand-built in Denmark. The OSPW X System for SRAM 1X is compatible with: SRAM Force 1X 11 speed with Type 3 clutch and 8 o'clock cage lock position* (see Tech Data sheet for more info) SRAM Rival 1X 11 speed with Type 3 clutch and 8 o'clock cage lock position* (see Tech Data sheet for more info) In the box: One complete 14-tooth/18-tooth OSPW X System for SRAM 1x CeramicSpeed bearing oil in a 15ml dropper bottle Sticker sheet Overview Guidelines
