We love the SRAM GX Eagle AXS Transmission Groupset for its flawless shifting and budget-friendly build. Made with all the same advanced tech as the X0 and XX transmission series but in a slightly trimmed-down version with fewer bells and whistles and heavier weight, the GX Eagle AXS Transmission Groupset is the perfect option for riders looking to get their hands on the newest tech without ripping a hole in our wallets. The transmission system redesigned the entire drivetrain and uses a new chain design for smoother shifting. The cassette has redesigned shifting channels so we can shift faster, smoother, and even under load. This drivetrain features a huge 10-52-tooth cassette range and has a derailleur that can move out of the way in the event of a crash, and individual parts can be replaced on the derailleur so we don't have to replace the entire derailleur.
