Sometimes big isn't big enough. For the power riders who aren't satisfied with a 50-tooth chainring, SRAM is now offering a modified version of the GX Eagle groupset that allows for a 10-52 cassette, as part of the new '520% Range' series. This means you no longer have to change your front chainring when riding on different types of terrain, and you'll always have the right range at hand, whether you're climbing a mountain or speeding down a hill. With this groupset, you have access to the best aluminum crankset SRAM has to offer. The wide range of components makes it easy to personalize your drivetrain.
