Best workshop chain tools 2025 rated and reviewed: for home use when replacing, repairing or shortening

Repairing or replacing a chain is a job all cyclists will one day have to contend with. While some of the best multi-tools house chain tools these are very much designed for roadside repairs. With many groupsets now 12 and 13-speed frequent chain replacement has become more important than ever to prolong the lifespan of your cassette and chainrings.

Doing this with one of the best chain tools makes this job much easier, they offer greater accuracy, are more ergonomic and have better leverage. They also offer far greater compatibility with a wider variety of chains so they can be used with most of the best road and gravel bikes.

For example our best overall the Topeak All Speeds is capable of splitting chains from 5-speed up to 12-speed, including hollow-pinned Campagnolo and SRAM flat-top chains.

In this guide, we have tested seven of the best chain tools. This testing focuses heavily on the tool's ability to accurately and reliably break a chain. A good chain tool also should be able to refit a rivet, loosen a tight link, and ideally have replaceable pins.

Using the chain hook

The Topeak All Speeds Chain Tool will accommodate chains from a wide singlespeed chain (1/8" type) to a 12-speed chain and it can also peen the hollow rivets on Campagnolo 11 and 12-speed chains. The tool is nicely made and incorporates all of the features that I would expect to see in a workshop tool.

The hollow body handle stores a spare pin and the chain hook. The pin in the driver handle is a spinning type allowing the tool to drive a rivet out without adding a rotating force onto it; it's a nice engineering touch. The pin stayed true throughout the test.

Using it with a selection of different width/speed chains I found that it drove rivets out very easily due in part to the leverage afforded by the sliding handle. I really liked being able to see how far out the rivet had been pushed so as to not push it completely free. This matters if you want to rejoin the chain in the old way. When rejoining the chain it was easy to see when you had centralised the rivet ready for the chain to be used. In the event of a tight link, there is a second chain bridge allowing the quick and easy loosening of this.

When using a Shimano rivet the tool has a neat function at the end of the driver handle. It has a chain pin breaker slot which is a bit neater than my usual method using pliers!

I enjoyed using this tool and liked the clear visibility of being able to see exactly where the rivet was in its travel. The smooth power from the handle was great and I liked having all the functions contained in the one tool. Very nice design.

The Park Tool CT-3.3 is made from steel and features a rugged design with its iconic blue adorning the pin handle. I think it's fair to say that you'd expect years of use from this tool especially as many bike shops use Park Tools daily.

It will accommodate all chains from wide singlespeed to 12-speed as well as SRAM AXS 12s, Campagnolo 13s and even half-link chains. Whilst it will work with Campagnolo hollow link chains (11-13s) it is unable to peen the reinstalled rivet.

Similar to the Birzman it has an adjustable chain bridge to automatically set the correct distance for each chain type. In practice, it seems a bit loose initially but once loaded up with a chain it settles in correctly and I had no issues with it during the test. In use, it has good power and pops a rivet out with ease.

Reinstalling the standard and Shimano type rivets was equally straight forward and I used the slot to snap off the Shimano rivet - a bit of an unofficial feature maybe. I liked that it was very easy to see how far out the rivet was, which helped with the removal and resetting of it.

The pin is a fixed type and replaceable but not included. Park do supply them as Part No. CTP. Also, there is nowhere on the tool to store the spare pin.

Like a few of the tools here, it was unable to deal with a tight link as there was no second bridge. Maybe it's now all about quick links, which I do like and use, but I'd still prefer the option...

Best value

There is little not to like about the Park Tool CT-5 mini-chain tool. A staple of my toolbox for years and it gets the job done. It performs most functions required of a chain tool to a decent standard and it actually offers very good compatibility. This is in part thanks to Park Tool's CTP-C replaceable pins which can be found on the industry standard CT3.3 tool.

The CT-5 only differs from the CT3.3 design in the design of the main body. Far more compact in nature and low in weight means you could carry it in a saddle bag if you wanted to. However, this compact size does limit leverage for frequent workshop use. For the once or twice-per-year chain replacement, it would be perfect.

One area the CT-5 stands out from the CT3.3 though is the dual bridge design which is perfect for freeing up those Shimano snap rivets once you have fitted them. Just make sure to be sympathetic to this design though as it is not designed for the heavy-handed.

The PRO chain tool 9-12 is the smallest tool in this guide but don't let that put you off as it is jewel-like in its machining. The writing on the body is very precisely etched and handily states its chain type capability.

Despite shortish pin and body handles there was plenty of leverage and the threading was some of the smoothest on test despite being the smallest diameter. The rivet was easy to pop out and reset, and again I had a clear vision of where it was in the process ensuring that I didn't completely remove it by mistake.

I felt that the rotating pin helped with the smooth action of this tool. At the back of the chain support, there is a hole to release a rivet and it worked to break off the Shimano-type rivet but there was no ability to adjust a tight link though.

PRO states that this tool has a "misuse prevention feature" only allowing it to be used with 9 to 12-speed chains. If you want to break a 1-9 speed chain you need to use their other model.

It worked very nicely with the 11-speed Shimano chain so I tried it with the narrow singlespeed chain being very careful to check for any compatibility issues. It worked fine. When I tried to set up the wide singlespeed chain it didn't look happy though as it was unable to sit squarely in the chain bridge, so I didn't proceed.

If you only want to deal with relatively modern 9-12 speed drivetrains (although it seems to cope with some others) with quick links then there's a lot to like about this tool.

Best ergonomics

The Lezyne Classic Chain Drive is a really lovely tool to look at and feels well constructed when in the hand. The wooden handle instantly sets it apart from the other tools in the test. It is the heaviest (just) in the test and also physically the largest, but the leverage from the long pin handle makes it very light in use. In that regard, it is similar to the Birzman tool. You only need to apply pressure with a thumb and first finger knuckle on the handle to drive a rivet out.

In use, the threaded chain support can be wound in or out to set the correct distance needed for the chain to sit correctly in the chain bridge. As the support has a good-sized slot machined in it you can clearly see how far through a rivet is, making the breaking and rejoining of a chain really straight forward. Then, if you encounter a tight link, the support may be wound back making the chain bridge effectively the second bridge.

Lezyne state that the Classic will deal with 8-12 speed chains (but not hollow pin chains) but I tried it using our selection of a Shimano 11-speed chain and connecting rivet, then the KMC Narrow and Wide singlespeed chain (rejoining in the old fashioned way) and had no issues whatsoever.

The pin is replaceable with a spare that is kept in the handle, and whilst it doesn't spin it didn't spoil the experience of using this versatile and powerful tool.

The Birzman Damselfly Universal is a really striking-looking tool with its angular styling. It has a sprung loaded chain bridge which allows any (1-12-speed) chain to be correctly set before having the rivet pressed out.

In use, I found that it had a nice action and needed minimal pressure from the thumb and first finger to rotate the pin handle. It was comfortable to hold the body handle and it replaced a rivet nicely too. You can use the top of the slot to break a Shimano connecting rivet off. Neat! However, it doesn't loosen a tight link as there is no second bridge.

If you just want to set a chain to the correct length and rejoin with a quick link, then this tool does that job with style and panache. However, for me, the lack of a second bridge is an issue.

Honourable Mention

The KMC Reversible Chain Tool is the second smallest and lightest on test. The body and handle are made from steel whilst the body handle has a rubberized 'Kawasaki' green cover. The pin spins and it can swapped around if a pin breaks.

I found with the first couple of chain breaks that the rotating handle felt slightly graunchy compared to the other tools on test. I greased the thread a little and it became much smoother in action. Something to bear in mind.

It dealt with the de-riveting and re-riveting well apart from a couple of things of note. Firstly, when installing a Shimano rivet it was really difficult to remove the chain from the tool as the protruding end of the rivet was held captive in the slot (see pic 2 above).

There is a cover to the end of the slot that gets in the way. It took some waggling to extract the chain and once released the rivet end could be snapped off. The other issue is that if you wrap your fingers around both the body handle and the pin handle your knuckles clash as there is not enough room between the handles.

The sliding pin handle did give good leverage though and it accommodated all the test chains easily. However, the lack of a second chain bridge meant that I couldn't adjust a tight link... again! Spotting a theme here?

I haven't been able to see exactly what is reversible about it. It may be that the spare pin being double-ended is reversible? Each end measures the same length... So whilst a spare pin is included and is not storable on the tool, it does store a spare on the 'reversible' pin.

Conclusion

All of the tools here were very capable of driving a rivet out of a multi-speed chain, so If you are 'just' looking to do that task and then using a quick link. you won't be disappointed. The differences start to show themselves when dealing with older style chains and joining practices, alongside ease of use. Although they can be initially expensive, a versatile and quality chain tool will repay you with reliability and durability over time. It will make the job more enjoyable too!

The Topeak was my favorite tool with its ability to deal with everything on test, it was well made and is keenly priced. It was closely followed by the more expensive Lezyne tool. There was little to separate the Park Tool, Birzman and PRO tools and really it was just the inability to loosen a tight link that let them down. The LifeLine tool is able to deal with nearly every chain type but is a little fiddly to use/set up and finally, the KMC's handles are too close together for me.

Glossary

• Pin driver handle: The handle that you rotate to bring the pin to the rivet and then push the rivet through the chain
• Body handle: The handle that you hold to steady the tool
• First chain bridge: The most used section to support the chain allowing the accurate alignment of the rivet then to be driven out
• Second chain bridge: Used to loosen a tight link
• Anvil: used to peen the hollow rivets used in some Campagnolo 11, 12 & 13-speed chains. Not within the scope of this test but some tools have the ability

How we test

Firstly a chain tool must be able to accurately and reliably break a chain by removing a rivet, secondly it should be able to refit a rivet. Then it should be able to loosen a tight link, and finally should the pin break on the tool it should be replaceable. Otherwise, the tool would be rendered unusable.

Next there are some 'nice to haves' namely:

Does the pin spin? When a rivet is moved in or out of a chain bushing we want the pressure applied in one direction, across the tool. With a static pin, you also apply a rotating force to the rivet as well. It's not a deal breaker but it is a nice engineering touch.

Is the tool supplied with a spare pin, and can the spare be stored in or on the tool? It saves it from being lost or mislaid.

Finally, does it have a chain hook? This stops the chain from being under tension (from the derailleur) when removing a rivet or quick link and firing important bits of chain across your workspace when you've forgotten to drop the chain off the front ring to detention the chain.

Initially, all tools were used to break a Shimano CN-HG701 11-speed chain (11/128" type 5.5mm outer width) and then to connect it back using a Shimano 11-speed connecting rivet (CN9000). If able to, the guide part of the rivet was snapped off using the tool and finally a tight link was loosened.

Then, I used a narrow KMC Z610HX singlespeed chain (3/32' type 7.4mm outer width) and drove the rivet out, then rejoined the chain and finally loosened any tight links.

And lastly, a KMC Z1 wide singlespeed chain (1/8" type 8.65mm outer width) was tried using the same process as before.

If a tool was unable to accommodate a chain in the bridge it wasn't tried. The chain had to sit down correctly in the bridge and sit squarely in the tool.
