The SRAM XX1 Eagle Groupset Gold - 10/50 is a brand new groupset which represents SRAM's newest 1x drivetrain technologies. Not only is It lighter and tougher, but it is also quieter, more durable and more precise, making it engineered for greater performance. It features the brand new X-Dome Eagle cassette which is a 12-Speed 10/50 cassette that offers an optimal 500-percent gear range at a considerably lighter weight than 2x systems. It carries with it the X-DOME architecture, which, independent tests have concluded, yields the strongest cassettes on the market. New shifting characteristics improve both, inboard and outboard shifting, as well as chain retention. The Gold cassette uses a Titanium Nitrate coated finish which has less friction and the Carbon cage on the rear derailleur teamed with lightweight hardware make it light and tough.
