SRAM XX1 Eagle cassette 12-speed X-Dome XG-1299 10-50 teeth gold
The evolution of Srams XX1 group is called Eagle. If you look at the details of the group, this name definitely makes sense. While you often had to make compromises with the 11-speed cassette with 10-42 teeth gradation of the XX1 cassette and either the fastest or the slowest gear was missing, you are with the 12-speed XX1 Eagle cassette with its huge gradation of 10-50 teeth free in every terrain like an eagle. With the XX1 Eagle, Sram manages to combine the advantages of 2-speed and 1-speed drives: a gear ratio range of 500%, which is on the level of 2-speed groups, in combination with the easier-to-use and lighter 1-speed Drive.
With the proven SRAM X-Dome technology, the XG-1299 Eagle 12-speed cassette is one of the most durable and stiff cassettes on the market. SRAM achieves this by milling the cassette from a block. This manufacturing technique also allows the weight to be kept extremely low even with durable steel pinions. Only the 50 end pinion is made of aluminum. Compared to the XX1 cassette, the individual sprockets have been optimized for an improved shifting performance and an improved fit of the chain.
