Bike Chain Repair Tool kit - Bicycle Chain Breaker Tool, Master Link Pliers, Chain Wear Checker for 7-11 and Single Speed Chains

I got this tool set off Amazon, costs just $13. Haven't replaced it yet, but used the tool so I can remove the chain, strip the grease, then add drip wax. I've used the chain breaker tool for new chains on other bikes. https://www.amazon.com/dp/B07YNGVD4Z?th=1
