🔗 Black Chain Checker Plus II: Enhancing SEO Review

No detailed instructions on the box. Like others, you have to search to read them on Pedro's website or YouTube videos. Every cyclist who maintains their own bike needs this tool.

Perfect tool. It falls between the simplest chain checkers and the overly complex and large ones. I don't get to use it often but it seems accurate, easy to use and a nice addition to my cycling toolbox.

This is a simple and convenient way to check if your chain is worn enough to require replacement. If you want to know wear curves from 0.25 to 1.00, you should buy a different sensor. This only works to show you when it's time to replace your chain.

Very functional tool for versatile use. Obviously having a chain life sensor and saving on more expensive gears is worth the investment. Also, a second pair of hands with a chain keeper is a great extra when installing or removing the master link. It's worth noting that this latest version also adds 75% caliber. I have attached some photos which show good quality and detail. The tool also has a very nice glossy finish and is made of a very rigid material that will not flex.

Works perfectly. The hook sequence is a bit strange and not entirely intuitive. The instructions are printed right on the side of the tool, which is handy, but I'm wondering if they won't rub off over time. Of course, by then you'll be quite adept at handling this flimsy material anyway. Please note that on a good chain, the last hook/tongue should not be included in the chain at all. The tongue has two tiny extra notches to indicate if they fit the chain, 0.5% wear (change time) and 0.75% wear

Among similar tools, this one was better and more efficient. The chain hook is great and easily holds the chain in place while I hooked up the SRAM performance links. Accurately showed no wear on my new chain. Add a lifetime warranty and a competitive price compared to other tools that only do one of the above and it can't be beat. Gold on black markings is a nice elegant bonus. Great job Pedro! Gears: Chain: SRAM PC 1110 (11-speed) Cranks: Shimano FC 2300 (probably "8"-speed, but works well…

I used the Park CC2 circuit tester but found later that it was inaccurate. I recently had to put a new chain on my fat bike when the park tool showed 75% wear (park recommendation). I bought a Pedro Checker and tried it on my old chain. This showed that there was still a lot of life in the chain. It measures chain wear differently than the Park tool. The Park tool is used at the local bike shop, and since it wears out more than the Pedro tool, the bike shop may sell you a new chain sooner than…
