I'm very happy with these tools.The chain wear gauge is accurate and does it's job perfectly. It has labelled sides for 1mm wear and 0.75mm wear.The quick link pliers are good and although the paint can chip off easily, that doesn't affect the function. The handles are comfy and make splitting a chain with a quick link a breeze.The chain breaker is great. The additional thumb screw to hold the chain in place is a fantastic addition, I have no idea how this isn't included in more expensive tools!The included chain hook is handy and the spare pin gives ease of mind to anyone that has bent or broken a pin before.All in all, this a great set of tools for the price (it would even be a great set of tools for a higher price). This is a must buy for anyone that's struggled working on their chain before.

The chain wear tool measures 0.75% and 1% chain stretch, which according to a video I saw elsewhere are calibrations most suited to single-speed set-up. If you have something else then you could still use the 0.75% measure to identify replacement time.The chain splitter tool does what it needs to do on a single speed chain, and would likely work on any other chain too.The double-sided pliers made removing the old chain a cinch, however I struggled more with securing the link on the new chain.I'm a novice at this though so don't let my experience sway your opinion too much.The set also usefully came with some single use chain links which might be useful in an emergency, but as the chain I bought came with a super strong link I can't comment on their quality. Probably perfectly adequate if you're in a jam and have them with you...

Chain breaker v poor quality and twisted and bent rather than actual do what is was meant to.Off to find a better one…

Yet to be used but appears to be a good buy so am happy to leave good review

Does exactly what it needs to - ads flexibility to my own bike repairs

Chain broke as I got to the train station so parked up abs went home. Back the following Sunday evening for a quick fix and away. Wasn't amazing but did the job

Have not used yet Got for a breakdown which thankfully hasn't happened but looks capable of doing it's job

A good mix of tools to check for chain wear, removing a pin from the chain to take it off, or locking and unlocking the master link if your chain uses them, if they don't then you get a couple of them. For the price they do the job, however the chain checker tool received was bent with a slight curve which no doubt reduces how accurate the wear on the bike chain actually is.
