If you're after every possible advantage when you toe the line this season, enhance your drivetrain's performance with the UFO SRAM 12 speed chain from Ceramic Speed. This high-speed racing chain is carefully selected and optimized by hand in Denmark and the techniques and lubes used are proven to help you save watts on race day. Ceramic Speed claims an impressive efficiency savings of 25% over a stock SRAM Force AXS chain. We recommend using the chain just on race day, as it is designed for only 600 km or 370 miles of clean and dry riding. Riding in wet or muddy conditions will shorten the lifespan of the optimization. The CeramicSpeed UFO Chains go through a multi-step process that involves polishing the link's sliding surfaces, cleaning off the inefficient factory lube, and the application of a wax lube and Teflon powder to achieve the chain's best possible efficiency.
