Product Information

Full details

The Pedros Chain Checker Plus II is an essential maintenance tool for cyclists of all levels who want to prolong the life of their drivetrain components and reduce long-term repair costs. By providing accurate 0.5% and 0.75% wear measurements, it helps you identify exactly when a chain needs replacing before it damages your expensive cassette or chainrings. While the tool is exceptionally precise and durable, users must remember that it requires proper technique to ensure the three-point design engages correctly for an accurate reading.

FAQs

What is the difference between a two-point and three-point chain checker?

A two-point tool often includes roller wear in its measurement, which can give a false reading. A three-point tool, like this one, ignores roller play to measure only the pin wear that actually stretches the chain.

When should I replace my chain?

You should replace your chain as soon as the 0.75% wear side of the tool drops into the links.

Can I use this on a single-speed chain?

This tool is designed primarily for multi-speed derailleur chains. It may not provide accurate readings for wider, single-speed specific chains.

How do I use the chain hook?

Insert the hook into two links on either side of the break in the chain, allowing the ends of the chain to hang loose so you can easily install or remove a master link.

Is this tool compatible with 12-speed chains?

Yes, this tool is officially approved by SRAM for use with their EAGLE 12-speed chains.

Troubleshooting

The tool seems to show wear even on a brand new chain.

Ensure you are using the three-point contact method correctly. If only two points engage, the measurement will be inaccurate.

Difficulty getting the tool to seat into the chain.

Check that the chain is free of excess debris or hardened grease. Clean the chain with a degreaser and try again.

Pros and Cons

Setup, Compatibility & Care

This tool requires no formal setup. Simply store it in a cool, dry place to prevent surface oxidation. It is compatible with most multi-speed bicycle chains, including SRAM EAGLE 12-speed drivetrains. To maintain accuracy, ensure the chain is clean and free of excessive grime before measuring, as build-up can lead to inaccurate results. The tool is constructed from high-quality, laser-cut steel, which is resistant to bending under normal use. Avoid using the tool as a pry bar or for tasks outside its intended scope to keep the measurement points calibrated.
