If you have a bike with old, worn or hex head brake pins this is a great replacement product. I specifically recommend anyone with hex head pins replace them with these. Brake pins tend to sieze up and with the hex head they tend to round out making it difficult if not imposible to remove. While these won't prevent sieze up, only your maintenance and anti-sieze can do that, they do make easier to remove. They are a high quality and very durable product.
