Park Tool CT-3 Chain Tool

(discontinued)

I purchased my Park Tool CT-3 over 10 years ago and I do have to say, it has been fantastic! Below are my impressions:

Future Proof:

The best thing about it is that it has been able to keep up with the times, as if it's 100% future proof. When I picked it up, I was running a 9 speed chain, since then I have moved up to 10 and more recently to 11 speed. The best part about these changes, besides the obvious increase in gears, is that the CT-3 works for each chain type. Although Park Tool states that this tool is only compatible with 5, 6, 7, 8, 9, and 10 speed chains, I have been able to use it just fine on my 11 speed drivetrain. I'm sure it will be compatible with Sram's new 12 speed "Eagle" chains as well.

Function:

The CT-3 chain breaker has impressive driving force. They is probably thanks to the bolt's vast amounts of threads running, seamlessly through the base of the tool. At no time have I ever felt like these threads were going to strip or that the tool was near failure. It's pretty much built to last. Helpful tip: Fully unthread the driving bolt of the chain breaker and throw some high quality grease on the threads and then thread it back into the base plate. Doing so will make breaking chains even more effortless.

The materials are very high quality and Park Tool also vinyl dipped the handle of the driving bolt which makes it very comfortable to use.

One thing to watch out for:

One thing to keep an eye out is that the chain is sitting flush and centered while in use. Having the chain not centered can cause the pin to push unevenly which will cause the pin to either bend or break. Personally this has never happened to me but I have had a few friends who have broken these pins by being careless. If for some reason it happens, these pins can be replaced at a very reasonable price. (they are currently only $1.49 a piece online.)

Bottom line:

If you are a home mechanic or just can't reason spending $10 at your LBS to replace a worn out chain, I would strongly recommend getting the CT-3 chain breaker by Park Tool. It's high quality and is built to last forever. At less than $30, you'll be glad to have this tool.
