Align the cassette with the Comet 4 - bolt weld - on European bearing hanger and use the bolts to secure it firmly. Check that the 5 threaded 8mm seat stay holes are properly positioned and use the 6mm pinch bolt to keep everything in place. When it comes to maintenance, regularly inspect the bolts for tightness. If you notice any signs of wear or looseness, tighten the bolts carefully. Keep the cassette clean to prevent dirt and debris from affecting its performance.
