The XG-1275 GX Eagle cassette provides all the benefits of 12-speed Eagle but without the huge price tag found on the X01 and XX1 models. SRAM's Full Pin technology permanently connects the precision-engineered steel cogs with high-strength stainless steel pins, resulting in an open design with similar performance to the high-end cassettes with only a small weight penalty. X-Glide 2 technology provides quick and precise shifting up and down the cassette, even while under load, and the 10-52t option provides riders with up to a whopping 520% gear range.
