SRAM has expanded their GX, X01, and XX1 cassettes to a 520% range with new 10-52t cassettes. The two additional teeth take Eagle one tooth beyond that of Shimano’s current 10-51t range, and all new SRAM Eagle derailleurs will come with a slightly reconfigured cage to accommodate the massive cog, and a fresh look. The redesigned derailleurs are backwards compatible with older cassettes.

All that range should mean that riders with a little extra leg muscle can mount a larger chainring without affecting the bike’s climbing spinnability. There is however an even larger gap between the 1st and 2nd gears. The cassette has the following profile: 10, 12, 14, 16, 18, 21, 24, 28, 32, 36, 42, 52.

In addition to the extra teeth, the three interchangeable transmission sets can now be purchased in a variety of different colors. The GX cassette, carbon or alloy cranks, and chain will have a Lunar and black colorway. The GX Eagle Dub crankset is refinished for a cleaner look. They have also added a carbon GX Eagle crankset for $275.

The X01 kits get a black chain and cassette, and XX1 chains and cassettes are available in gold, rainbow (aka oil slick), and copper.

MSRP for the wider range GX cassettes is $215 (€220), X01 is $385 (€391), and the XX1 cogs are $449 (€457) for any of the three hues. As a whole, the GX Eagle groupset costs $545 with an aluminum crankset.

SRAM also made a new ‘B-gap tool’ for more precise B-limit screw adjustments.
