Margay Brava M10x50 Flat Head Allen Bolt for Extra Long Cassette Bolt

This 10mm x 50mm flat - head Allen bolt is a game - changer. It enables you to securely bolt the seat stays to the inside of the cassette, rather than the outside, offering a more streamlined and stable installation.

Using this bolt is easy. First, make sure the area where you'll install the bolt is clean and free of debris. Then, insert the bolt into the appropriate hole on the seat stays and cassette. Use a suitable Allen wrench to tighten it, but don't over - tighten as it may damage the parts. When it comes to maintenance, regularly check the bolt for any signs of looseness. If it's loose, tighten it gently. Also, keep it clean to prevent rusting. Store it in a dry place when not in use.
