It's a versatile part that fits multiple 12 - speed cranks including XT and SLX models such as FC - M8100, FC - M8120, FC - M8130, FC - M7100, FC - M7120, and FC - M7130.

Using this fixing bolt is easy. First, make sure your bike's crank arm is clean and free of any dirt or debris. Then, align the bolt with the holes on the crank arm and gently thread it in by hand to avoid cross - threading. Once it's hand - tightened, use an appropriate wrench to fully tighten the bolt, but don't over - tighten it as this could damage the parts. As for maintenance, regularly check the bolt for any signs of wear or looseness. If it gets dirty, you can clean it with a mild bike cleaner and a soft cloth. When not in use, store it in a dry place to prevent rusting.
