How to replace your quick links
Hot waxing your chain requires you to take the chain off every time you wax. Most chain manufacturers state that the quick links are single-use. This is the safest option for sure. However, not everyone replaces their quick link every time.
If you do reuse it, here’s how to keep it safe: If it doesn't provide you with that snappy click when closed, it should be replaced. For a major event, like a race or Gran Fondo, always use a new quick link.
Do not reuse a quick link more than five times. The Connex quick links are an exception. Since they don’t rely on a click but rather on a unique angle to close them, you can use them over and over. In fact, they have the same lifespan as your chain.
The perfect quick link for anyone who waxes, fitting all chains except SRAM Flattops.
