Ideal for SRAM Eagle AXS or mechanical drivetrain owners, home mechanics and workshops setting up or maintaining 50T or 52T Eagle cassettes.
The SRAM Eagle V2 Rear Derailleur Chaingap Adjustment Gauge is a dedicated B-gap tool for setting the correct distance between your rear derailleur and cassette. It works across Eagle AXS and Eagle mechanical drivetrains, including Eagle XX1, X01, GX, NX and SX rear derailleurs.
Use it with the chain on the largest cassette cog to position the derailleur correctly for either a 50T or 52T largest cog. Correct chain gap helps your drivetrain shift more quickly and responsively; too much gap can make shifting sluggish, while too little can cause interference at the larger cogs.
The gauge is small enough for a ride bag or toolbox, making it useful for initial setup, drivetrain changes and ongoing maintenance. This Eagle V2 version replaces earlier Eagle gauges that do not support 52T cassettes, so it is the practical choice when your drivetrain uses either a 10-50T or 10-52T Eagle cassette.
