I am thinking about getting a Park ct-5 chain tool versus something smaller / lighter that might be part of some sort of multi. I've needed a chain tool only a very small number of times over many years. I have never had a chain fail on the road. Is the park worth it's weight and size for carrying in a road kit? It seems like a bit much for a tool that does only one thing, especially when that one thing is so unlikely.


Though I need the chain tool now to replace a chain, I'm putting together the usual sort of carry-along bike tool kit for my road trips. I haven't decided whether to build upon separate tools or a multitool.

Thanks for your thoughts,

The good part tool is best left in your toolbox and used for regular maintenance like disassembly for chain cleaning and replacement.

The chain tool including with multitools tend to be weak as a kitten and will likely break (as many of mine have) if used frequently... but will do fine if you need to fix a chain once or twice over several years.

I've ridden many road miles and done lots of group rides. I can only recall one chain failure - and it wasn't mine. Still, if you want to be prepared for all eventualities (and be popular in the group) then having a chain tool along for the ride makes sense.

I have a CT-5. It is a well made little item that could probably be your only chain tool if you don't do much wrenching. The bigger, badder shop version (I have that one, too) is much easier on the digits during use, though. And I'm sure I'll be passing it down to my posterity as it is simple and over-built.

The chain tools that come as part of multi-tools are generally more frustrating to use and take more effort in the process. If you can stand a few extra ounces and have the room in your seat bag, the CT-5 would be easier to use when you're already in a dark mood...

I've had awesome luck with crank brothers Multi 17, that has the chain tool in it.
It works very well considering that it doesn't have a live centre, it's not as convenient to use as a specific chain tool if you have to put a chain back together on the road / trail, but it beats walking.

Topeak Alien would be second choice also has tire levers which are handy if you need them.

I have the Topeak Alien II multi-tool. I was quite impressed with the chain-tool on it. Works surprisingly well I found out. For back at the shop - I have the Park CT-3, and I very much love it.

The CT-5 is an excellent take-along chain tool. As another poster already mentioned, if you don't do too much wrenching it could be your only chain tool. In 15+ years of riding I have only had two chains fail on the road. While rare, I was glad to have the CT-5 when I needed it.

Just FYI..Here is a little take-along tool kit I put together that includes the CT-5.

I like the CT-5. I have that and the heavy duty shop one whose Park Tool designation I can't remember. I take apart my CT-5 to make it more compact and wrap it in electrical tape to hold it together. Tape can also be doubled for other uses, such as taping a broken spoke to others to limp home, etc.
