Clever Measurement Tool: A worn chain can make shifting difficult and damage the drivetrain quickly. The bike chain checker tool contacts the chain in three positions skillfully to indicate the chain wear easily and quickly, which can protect the drivetrain better
Wide Compatibility: This bicycle chain checker tool is a plug in gauge that matches any 5 to 12 speed derailleur chain and is designed to indicate accurately when the chain reaches 0.5% and 0.75% wear, which is the point that most manufacturers recommend replacing
More Accurate Measurement: The overall design of this chain checker tool is longer, so that there can be enough samples to obtain more accurate measurement data, which can meet the needs of most cyclists
Durable Quality: The bike chain wear gauge is designed with harsh usage environments in mind and is made of high quality stainless steel, which is more resistant to oil and corrosion. Bike chain measuring tool with robust and stable materials provide superior durability for long term service
Check Anytime Anywhere: The stretch of the chain is difficult to notice visually. The bike chain wear tool can detect the chain at any time that check whether your drivetrain in good condition. We offer a 100% satisfaction guarantee

Quality Item
Machined out of stainless steel this guide strikes a balance between high quality and a good entry price. For those of us that ride a lot. A new chain is cheap insurance against straining more expensive components

Easy to Use – Unambiguous Reading
Super Easy to use. No ambiguity about the reading. Nice! [Do I know if it is accurate? No -but I assume it is given that it is just a straight piece of metal cut to a specific size.]

Great chain checker!
This is a great quality chain wear checker. This is identical to most others, but reasonably priced. The pricing on the more popular brands are moronic, even if you own a bicycle repair shop.

Simple tool well made.
Simple tool well made. My previous chain checker only had 0.5 or 1.0, but 0.75 threshold is recommended for my 11 speed. Good value; why spend more?

MATINA Bike chain checker tool
MATINA Bike Chain Checker Tool this is a very good tool which is absolutely needed if you own a bike. The MATINA Tool does the job, should prove to be durable and will fit in most tool bags. Not as pretty as PARKS CHAIN CHECKER TOOL, but pretty not required to check chain.Great value for the money and I would buy again.

Easy to check chain wear
Every time I get my bike tuned-up, they tell me that I need a new chain. I got this to be certain that they were accurate. It’s very easy to use, and I watched a video on Youtube that confirmed it.

Ok quality
Measured 0.6% and 1.2%. Also confirmed with measurements on an used chain against the Pedro’s checker – Pedro failed it while Matina thought it was still good. It is smooth on one side and rough on the other. I guess if I file it down to make it smoother it might fall within the spec.
