I enjoy riding in muddy conditions, so my bike and drivetrain are always covered in mud. I previously used a Shimano derailleur, and it was a nightmare; I constantly had issues with the 10-tooth cog because the Shimano derailleur's chain tension was far too weak. I’ve since upgraded to a SRAM GX derailleur paired with an X01 shifter, and now everything works perfectly with no issues at all
