The Evolution of Sram XX1 group carries the nickname Eagle to German eagle. If you look at the details of the group, the name makes perfect sense. While the 11-speed often compromises had to make cassette with 10-42 teeth gradation of XX1 cassette and either the fastest or the slowest gear was missing, one is with the 12-speed XX1 cassette Eagle with its huge gradation of 10-50 teeth in any terrain free as an eagle. Sram manages the XX1 Eagle unite the advantages of 2-way and 1-way drive: A Translation margin of 500%, which is at the level of 2-groups, in conjunction with the easier-to-handle and lighter 1 times Drive.
Using proven SRAM X-Dome technology, XG-1299 Eagle counts 12-speed cartridge to the toughest and stiffest cartridges on the market. This works SRAM by the milling of the cartridge from a block. This manufacturing technique also allows to keep the weight extremely low with durable steel pinions. Only the 50 final gear made of aluminum. Opposite the XX1 cassette the individual sprockets are optimized for improved Schaltperformence and an improved fit of the chain.
