Good tool, does the job
What’s not to like about Park tools. A bit pricey but accurate (tested the old and new chains) and easy to read.
Reviewed in the United States on September 7, 2024 by Arnie L. Wolff
Simple, accurate, durable
This tool measures chain-wear and it's very simple to use. The bottom of the tool has two metal pins, one pin is mounted to a lever and is offset in a way that changes the spacing between the pins when the lever is moved. This allows you to very precisely measure how much a bicycle chain has stretched. The stretch amount is visible through a small window. The tool is machined out of solid aluminum and the color is anodized (not painted). There are no plastic or fragile parts. The tool will never wear out -- one is all you'll need for the rest of your bike-riding life. Chains have a sequence of narrow & wide links. Each narrow & wide pair of links on a new chain will measure exactly 1.0" from center of pin to center of pin. If you were to use a ruler to measure 20 links (10 "pairs") it should measure exactly 10.0" on a brand-new chain. The chain will stretch with use as the hinge points wear. 1/16th of an inch is normal -- at 1/8" it's time to replace the chain. But using the Park Tool is a easier and faster than using a ruler. Set the lever to the "0" position and set the tool on your chain (keep mild tension on the chain to get an accurate reading -- measuring a chain hanging slack will not be accurate) so that the pins on the tool are between the links on your chain. Push the lever until it stops then read the stretch value through the window on the tool. A brand new chain will measure .0 -- any used chain will have some stretch. Values below .5 are considered normal/acceptable amounts of wear (the tool reads from 0 to 1.0 in .25 increments.), but above .5 means your chain will need replacing soon. I replace my chains when they read .75. Why do you care? Chains are relatively inexpensive and easy to replace, but if they're not replaced they can create problems. The chain will begin to slip and jump -- usually under heavy load such as trying to ride up a steep hill or on an aggressive climb on a trail (which is exactly when you _don't_ want that to happen). A stretched chain will also wear the sprockets -- it'll mildly affect the front chainrings, but it can more rapidly affect the rear freewheel or cassette and these are more expensive to replace. If you ride aggressively on trails you should be checking your chain about every 100-200 miles of riding. If you ride more gently or only on mostly flat streets then you may only need to check every 300-500 miles. I give this tool 5 stars (and I'm not one to just give out five stars because I bought one myself) because it's simple to use, it's easy to read, it's accurate, and it's constructed of durable materials -- not cheap plastic parts -- down to every detail (including anodizing the aluminum instead of painting it -- so there's not even any paint to wear off.) They did everything right when they made this tool. I couldn't ask for anything more.

Finally a chain tool that works
Easy to use, works with all the narrow 11 and 12 speed chains, a must have for every cyclist if you want to extend your cassette's and sprocket's lifespan.

A Must have for weekly riders
Works great but instructions note doesn't work with SRAM Flattop or T-Type chains for those you need the CC4.

Cheaper than new drive train components
Excellent for checking your chain stretch before eating cassettes and other expensive stuff. Should have bought one long ago.

Works great
I have two of the old style Park Took chain stretch checking tools. One is the shorter version, the other is the longer version. So, I was able to test this new one against the others and it is spot on accurate. Much easier for me to use as well.

No more guesswork
Like most Park Tool products, this one did well what it was designed to do, and made the results easy to understand. I highly recommend this to help you obtain the maximum life out of your bike's rear cogs and front chainrings.
