Sram just announced an update to their eagle drivetrains with new 10-52 cassettes for GX and above, new derailleurs to handle the extra range, GX got a carbon crank option, and new colorways.
Must have been killing them that Shimano’s 12-speed went to 51 teeth so they had to do something about it. I don’t like that they decided to just swap the 50 tooth cog for the 52 so now there’s a giant 10 tooth jump from 42 to 52. Pretty cool that they brought carbon cranks down to GX, though I didn’t see a price listed. The new colors look pretty cool too for those that want the top level drivetrain but weren’t a fan of the gold or oil slick colors.
