SRAM Eagle B Gap Tool (50T/52T, AXS and Mechanical)

The SRAM Eagle B Gap Tool is a chain-gap adjustment gauge for setting the correct B-screw position on Eagle rear derailleurs paired with 50T or 52T cassettes, both AXS and mechanical. It's a small but essential setup tool — correct chain gap is what makes an Eagle drivetrain shift the way it should.
