1Free SRAM AXS Wireless Drivetrain Upgrade is only available on compatible bikes. Buyer must purchase a bike with a SRAM GX, X01, or XX1 drivetrain. All other bikes are excluded. In some cases, non-compatible bikes may unintentionally indicate that they include the Free SRAM AXS Wireless Drivetrain Upgrade. These bikes will not be upgraded for free. The buyer may choose to upgrade the drivetrain on their new bike to include a SRAM AXS Wireless Drivetrain, but the upgrade will not be free of charge. Please confirm that the bike you are interested in buying has a SRAM GX, X01, or XX1 drivetrain if you would like to take advantage of this promotion. The upgrade kit will match the level of drivetrain already installed on the bike. For example, if a bike features a SRAM GX drivetrain, the included AXS upgrade kit will be a SRAM GX AXS upgrade kit. This promotion will run while in-stock supplies of SRAM AXS upgrade kits last. In the event that SRAM GX AXS kits are sold out, a bike with SRAM GX will not be upgraded with SRAM X01 or XX1 AXS. This promotion is on a first come first served basis.
