The 1x train rolls on with the SRAM GX Eagle. Perfect for the everyman the XG-1275 Eagle cassette uses the same design but gains more bang for its buck being made through more traditional routes. This means it is a little heavier, but weight is still saved with the exclusion of the front derailleur and sprocket. Using FULL PIN technology and the X-Glide 2 that means you get that same amazingly smooth and reliable shifting as the top level components you too can try the next best thing in mountain biking. Technology FULL PIN™ FULL PIN™ technology uses eleven lightweight, stamped steel cogs held together with 123 high-strength stainless steel pins. The result: a cassette that’s extremely light, durable and equipped with SRAM’s super wide 10-42 gear range that’s a perfect fit for any ride. The open design similar to our X-DOME™ cassette aids in mud clearance, giving you cleaner shifting performance and longer component life. X-Glide 2 X-GLIDE™ 2 is next generation of SRAM X-GLIDE™ technology optimized for the EAGLE™ 12-speed cassette. It provides quick, precise, power-on shifting performance throughout the gear range, and increases chain retention on larger cogs.
