Sram XG-1290 12-speed 10/28T cassette sprocket

SRAM XG-1250 sprocket cassette for 12-speed systems with SRAM XDR mounting technology. The advantages are clear: with the same combination of sprockets, the cassette has become even lighter. Additionally, weight can be saved from the cranks, as smaller chainrings are needed for the same maximum range as with an 11-sprocket cassette. The extra 12th sprocket allows the cassette to be used in combination with the eTap AXS 1-speed group. Compared to the previous version, the XG-1290 cassette is compatible with SRAM eTap AXS rear derailleurs. The result is even faster and smoother gear shifting.
