This kit is designed as a direct fit for SRAM X0 and X9 rear derailleurs. We do not recommend using it with other derailleur models as the mounting hardware and pulley dimensions may not align correctly.

You should consider replacing your pulleys if the teeth have become sharp or pointed, or if you notice excessive side-to-side play in the pulley wheels. Worn pulleys often lead to noisy shifting and decreased drivetrain efficiency.

Generation 2.1 refers to the specific design iteration of the derailleur hardware. It ensures that the pulley dimensions and bushing tolerances are an exact match for your existing derailleur cage, making for a straightforward installation.
