Replacing a broken bicycle chain is more effortless if one has the best chain breaker tool in hand. Chains are the driving force of bicycles, allowing the rider to transmit leg power to the rear wheel. Unfortunately, bike chains are not impervious to wear. They can break, get bent, or lose the pin that connects two chain links.
While chain breakers are a simple tool, many products on the market fail to meet bicycle owners’ expectations. Some breakers do not consistently drive the chain pin straight through its slot, while others are sloppy or weak. That is why bikers must choose the right tool to add to their bike repair kit.
We determined the following factors crucial in choosing the right possible chain breaker bike owners should buy.
- Compatibility: No chain breaker works on all bicycle chain system types. Many chain breakers work only with Shimano and SRAM products because of the two systems’ similar characteristics. Some products can also accommodate a limited chain link size, while others have a universal design.
- Ease of Use: What is the point of buying a chain breaker if it is difficult to operate? A chain breaker’s ease of use is a function of its overall design. The different components must work seamlessly together to make it easier for the biker to remove chain pins and replace the links.
- Construction: Ideally, the tool’s pushpin must never break under pressure. That is why it would be best to look at the product’s overall construction to determine its strength and durability. In general, all-steel construction is better than composites; although some companies use aluminum and steel alloys.
Other factors are also important when buying a chain breaker tool. We shall discuss these additional parameters in our comprehensive buying guide while presenting them in the following product reviews.

Top 12 Chain Breaker Tool Reviews
1. Park Tool CT-5 Mini Chain Brute
Park chain tools are some of the world’s best, favored for heavy-duty construction, thoughtful craftsmanship, and unquestionable performance. The Park Tool CT-5 Mini Chain Brute is one such tool that many bikers use today for emergency bike chain repairs on the road.
It is almost unimaginable how a tool this small can be a life-saver on any biking adventure. Not only is it light – weighing only 2.4 ounces – but the chain breaker also has a streamlined design. It is perfect for slipping into one’s back pocket or stashed inside a biker’s pouch.
Despite its minuscule size, this Park Tool chain breaker is as tough as hardened steel. It features high-strength alloy to give bicycle owners a durable product that will never give up on them in an emergency.
This tool can accommodate almost any bike chain type with a 1/8-inch width, including the 12-speed chains of Shimano’s XTR and SRAM’s AXS models. It also fits single-speed chaining and bicycles with 5-speed to 12-speed systems.
Owners of bikes with older chain styles will also love this pocket-sized breaker tool. It comes with an integrated shelf for loosening the super-tight and stubborn chain links of older models. Its pin is also replaceable, although I do not think it is necessary because of the product’s heavy-duty construction.Heads-up: While its diminutive size is a welcome attribute, it can also be the chain breaker’s Achilles heel. The drive handle is short, reducing one’s leverage. It may take brute force to turn the handle if the chain pin is too tight. Moreover, people with large hands may find holding the tool pretty challenging.
- Compatible with many bike chains with a 1/8-inch width
- Works with older chain styles
- Sturdy alloy construction and streamline design
- Uses replaceable pin
- Pocket size, weighing only 2.4 ounces
- Not for big-handed bikers
- Elbow grease required
2. Topeak Super Bicycle Chain Tool
Here is another worthy chain breaker to include in one’s everyday carry pouch. The Topeak Super Bicycle Chain Tool is almost similar to the Park Tool CT-5 Mini except for several additional tools that offer extra functionality.
I thought the CT-5 Mini was already light. This Topeak chain tool weighs less by 0.2 ounces, which is not much. Every fraction of an ounce matters if one has many tools in the repair bag. Part of its lightweight design is the company’s insistence on using premium-quality aluminum. Not only is this tool lightweight, but it is also durable.
People still learning how to use a chain breaker will love the extras that come with this minuscule device. There is a chain hook for securing the chain link section the biker wants to remove and a secondary chain link fence for securing the chaining. I find these tools exceptional in making chain pin removal as effortless as possible.
I also appreciate the integrated chain pin holder, perfect for slotting a brand new rivet if I need one on the road. The 5mm and 6mm Allen wrenches are also outstanding additions, enabling bikers to make instant maintenance or repairs wherever they are.
As for the chain tool itself, it fits most single-speed and multi-speed systems. The pin centers straight on the chain rivet, allowing users to slot it through the plates.
I am surprised that this tool does not cost that much, despite its construction and worthy additions.Heads-up: However, people with big hands will find manipulating the handle trickier than usual. It is also not compatible with Campagnolo chains.
- Works with single-speed and multi-speed chains
- Lightweight, pocket-sized multifunction tool kit
- Robust premium-quality aluminum construction
- Great value for the accessories (chain pin holder, Allen wrenches)
- Small for people with big hands
- Not for Campagnolo chains
3. Oumers Universal Bike Chain Tool
Despite its unfamiliar brand, the Oumers is the best bike chain tool if one only looks at positive customer reviews. This chain breaker is not only a reliable tool, but it is also one of the most affordable.
I like this tool’s overall design, particularly the grooved handle for a firm and more secure grip. It is suitable for people who have sweaty hands, allowing them to hold the tool as they crank the crossbar to remove a chain link. I also appreciate the lever’s finger-molded design, ensuring a better grasp.
The handle features a channel for accommodating an extra chain breaker pin. There is also a slot for the chain hook, the other end of which rests on the tool’s pin channel when not in use. It may not have Allen keys, but this pocket-sized device is all a two-wheeled road warrior ever needs when on an adventure.
I appreciate the tool’s stainless steel construction, giving it a more polished look. It can accommodate almost any bicycle chain with 7-speed to 10-speed configurations. Removing a chain pin is effortless because of the smaller threads than what other products have.Heads-up: While I love the lever’s design, it may be too dwarfish for some people. I also wish the company made this chain link breaker lighter because I cannot put it in my pocket without sagging. The good news is that its weight makes it more stable to hold during maintenance.
- Flexible universal design and stainless steel construction
- Non slip and comfortable grip with finger-molded design
- Backup breaker steel pin
- Pocket-sized device with small threads
- More affordable than other chain breakers
- A bit heavy
4. ATLIN Bicycle Chain Breaker Splitter Tool
The ATLIN Bicycle Chain Breaker Splitter Tool is another inexpensive option for bikers who want a reliable device for bicycle maintenance. This bicycle chain splitter tool has a more comfortable grip to make chain removal more hassle-free.
I like its lever design, allowing me to rest my thumb and index finger on its wide cross-section for more efficient turning. Aligning the chain rivet to the pushpin is pain-free because of the wide-open slot that ensures correct placement.
Some bike chain breakers do not center well, while others’ designs make it challenging to check the correct alignment between the pushpin and the chain rivet. This tool makes chain-breaking almost effortless.
The tool comes with a chain hook and an extra pushpin, perfect for stabilizing and securing the chain when working on a section.
I love the grip, which is similar to the Oumers. It will not slip off the hand, perfect for people with sweaty palms or butterfingers. The lever also feels solid and secure, giving the user the confidence to maintain their bikes. It easily translates to more exciting adventures on the bike trail.Heads-up: I wish the company did a better job of finishing the breaker’s body. It does not have a well-polished look, giving the tool an unpleasant cheap aesthetic. While pocket-sized, it does not necessarily translate to a comfortable carry. This tool will pull a baggy pant’s pocket down.
- Compatible with 7-speed to 10-speed chains
- Includes an extra push pin and a chain hook
- Easy to use due to the lever design with wide cross-section
- Heavy-duty construction
- Comfortable non-slip grip and crank
- Heavier than other pocket tools
- Looks cheap despite the quality
5. PRO BIKE Universal Chain Tool
Many chain breakers claim they have a universal design but can only accommodate a limited chain speed setup. When the PRO BIKE chain link removal tool says it is universal, it means it.
This tool can break the chains of bicycles with 1-speed to 12-speed groupsets, making it one of the most versatile chain breakers on the market.
Owners can fix their bicycles or their friends whenever they run into an emergency during one of their road adventures. It no longer matters if their bike mates have a different groupset because this tool will handle it.
Operating this handy tool is also a breeze, thanks to its oversized lever. One can slide the crossbar through its slot to lengthen one side and ensure better leverage during turning. The handle is comfortable and feels solid, too.
I like the way the thread centers the pin into the chain rivet. It is spot-on. Placing the chain is also error-free because there are no breaker elements to obstruct the view. I can say the company did a fantastic job with the tool’s design, ensuring optimum functionality and ease of operation.
While this bike chain breaker tool is heavier than the CT-5 Mini and Topeak Super, it does not weigh the pocket down as much as the Oumers and ATLIN did. One can slip the tool in the back pocket or stow it in a small pouch dangling from the bike frame.Heads-up: Unfortunately, Chromoly alloy is not as strong as stainless steel. That is why there have been complaints about the tool breaking its pushpin after several months. Additionally, it cannot accommodate the 12-speed groupsets from SRAM and KMC.
- Universal chain breaker design with comfortable, solid handle
- Hassle-free to operate thanks to the oversized lever
- Pin centers spot on, ensuring optimum functionality
- Compact and more lightweight than the Oumers and ATLIN
- Good value
- Incompatible with certain 12-speed chains
- Not as durable as ones made from stainless steel
6. Topeak Universal Chain Tool
Topeak returns with its take on a universal chain breaker. This lightweight, compact device is perfect for any cyclist who wants to maintain a sense of security whenever biking off-road.
This Topeak all speeds chain tool has a solid construction, despite weighing only 2.89 ounces. One can pocket this hand tool or slip it in a repair kit pouch. It will never weigh riders down, unlike other products that make their presence known by pulling the pocket to the ground.
I love its multiple groupsets compatibility, accommodating 12-speed chains as effortlessly as it does single-chain systems. A friend uses the tool on his Shimano, while another friend fixes his SRAM with this handy tool. We also have a neighbor who rides a single-speed legacy bike, and the chain breaker worked splendidly.
I like the handle’s hollow and removable design. One can unscrew it from the breaker body and slide it on a small Allen wrench for added leverage. Inside the handle is a chamber for accommodating a pair of extra chain pins. This feature is hands-on the best.
Replacing broken chain links is also hassle-free because of the included hook and chain pin breaker. I will not have to use pliers to cut the excess rivet.
While it has a universal design, it is unfortunate that this is not an 11 speed chain tool. The brand was upfront enough to caution buyers that the device will not work with 11-speed chains.Heads-up: Some people may also find the all-silver design too bland for the taste. The only accent one gets is the black rubber stopper that seals the bottom chain pin compartment.
- Compatible with many bike chain groupset types
- Comfortable handle with hollow and removable design
- Has integrated chain pin breaker and hook, secure chain pin compartment
- Solid yet lightweight construction
- Bland aesthetics
- Not for 11-speed chains
7. Park Tool CT-3.3 Chain Tool
Many bike repair shops worldwide have a ParkTool chain tool in their organizers because of its reliability, durability, and exceptional performance. People looking for a heavy duty chain breaker tool trusted by professionals globally and last many years should consider the Park Tool CT 3.3.
I admire this product’s robust construction. Starting with the vinyl-dipped handle, it feels secure on the hand when breaking and replacing a chain link. The grip is firm, while the textured surface gives instant feedback to what one is doing. It looks like the solid handle of a mechanic’s trustworthy adjustable wrench.
The lever is also exceptional. Although it does not have a sliding design, the crossbar spans sufficiently for maximum leverage. One can also slip a pipe tube over the lever for stubborn chain pins, such as those we see in rusty chains.
One can use this device on almost any bike groupset, including Shimano’s XTR and SRAM’s AXS 12-speed chains. It is also compatible with single-speed systems and any bicycles with standard 5-speed to 12-speed groupsets.
I love the breaker’s bolt that secures the pushpin at the tip. The company is also gracious enough to integrate a removable and replaceable pushpin. However, I do not think this is necessary because of the product’s professional-quality construction.Heads-up: Aside from its price, the only other comment I have about this product is its weight. On the bright side, its heft is a function of its solid-quality build. After all, seasoned bike repair shops will not want a lightweight tool they can toss in the garbage bin.
- Professional-grade chain breaker design
- Compatible with 5-speed to 12-speed groupsets
- Comprises an extra-long lever for maximum leverage
- Robust construction with removable, replaceable pushpin
- The price
- A bit heavy
8. A AKRAF Bike Link Repair Kit
One does not need a Halfords chain tool when bikers can get the A.AKRAF Bike Link Repair Kit. Not only is this a reliable chain breaker with an excellent price to match. It is also a complete kit for effortlessly removing and replacing broken chain links, master chains, and chain pins.
I am fascinated with the inclusions in this product. There is a 2-in-1 chain link plier perfect for removing and reconnecting the master chain link. The bike chain wear indicator also works like a charm in assessing the stretch of the bike chain and providing a picture of chain status.
A hook is present to stabilize the link section during chain breaking, while the breaker tool already comes with a pin splitter.
The product also includes three bike chain links perfect for initiating emergency roadside bike repairs. I cannot think of any big-name brand chain removing tool offering a set as complete as this.
One can repair any bicycle chain with 7-speed to 11-speed groupsets. If one has a single-speed bike, this tool will work, too. There is also no worrying about its construction because the company uses only heavy-duty steel.
Centering the pushpin is effortless, and securing the chain link is a breeze because of the chain breaker’s thoughtfully designed shelf. The oversized lever also makes twisting hassle-free, while the grooved handle will never slip one’s hands.Heads-up: Unfortunately, the tool does not work with 12-speed groupsets. I also found some complaints about the chain wear indicator tool being flimsier than the other tools included in the kit, getting dents after only several uses.
- Works with single and multi-speed chain systems
- Great value in return for a complete bike chain repair kit
- Easy to center the pushpins and secure the chain link
- Heavy-duty steel construction with oversized lever
- Chain link spanner not as heavy-duty as the other tools
- Not for 12-speed groupsets
9. SINGARE Multi-function Bike Repair Kit
The SINGARE bike chain removal tool is almost similar to the A.AKRAF bike chain repair kit, except for the missing bike chain link pliers. It is an affordable tool for people who do not want to spend more on a device they will not use frequently but performs well when needed.
Like other bike chain repair kits, I love this product’s thoughtfulness. It makes it effortless to perform emergency chain repairs on the road without looking for a professional bike shop.
The package already includes an easy-to-use chain breaker and a spanning tool for assessing a bike chaining’s integrity. Fixing damaged chain links is also easy because the device already comes with six extra chain links.
I like the handle’s center groove housing the pushpin when not in use. The chain hook also secures squarely on the handle and latches onto the breaker channel. The oversized lever is comfortable to hold without putting too much strain on the fingers and thumb.
The breaker body features a groove for spotting pushpin action, ensuring one does not dislodge the chain peg through the plates.
One can use this product to repair any bike with a single-speed chain or multiple sprockets in the 6- to 10-speed range. Friends and neighbors will be glad to have this tool in their bicycle under-seat pouches or even in their pockets.Heads-up: I wish the company included a bicycle chain link plier, even if that means paying a few dollars more. It would have made the repair kit more complete. There are also some minor issues with the product’s durability.
- Has easy-to-use chain breaker and a spanning tool
- An inexpensive chain breaker-check combo
- Oversized lever is comfortable to hold
- Compatible with most bicycle chain sizes in 6- to 10-speed range
- Includes extra bike chain links and removable pushpin
- No bike chain link pliers
- Durability needs improvement
10. Ponwec Bike Chain Tool
One problem with mainstream chain breakers is that they do not have other tools necessary for comprehensive repairs. The Ponwec bike chain link tool does. This repair kit has everything a bicycle owner needs to make shop-quality repairs on the road without breaking the bank.
The kit already includes a link plier, chain gauge, hook, and an extra pushpin or thimble. There are also three additional chain links to use in an emergency. With all these additions, I expected the product to cost more. Surprisingly, it is one of the most affordable on the market, making it an exceptional buy.
I love the plier because of its comfortable and solid grip. The chain breaker also has grooves on the handle, ensuring better stability when removing the chain pegs. The lever is stouter than most products on the market, allowing bikers to have a firm and secure hold as they turn the crossbar.
The tools feature hardened steel that will never bend or get dents. It is another surprise feature, given this product’s low price. The pliers and the chain breaker also feel solid on the hands. They are sufficiently heavy for improved handling during use.Heads-up: Unfortunately, I found a few complaints about the pushpin breaking after a few uses. Moreover, the handle can be short for some people. Sadly, the grip has a wide base that makes inserting a pipe impossible.
- Complete set of bike chain repair tools
- Compatible with most bike chain systems
- Hardened-steel construction ensures no bending or dents
- Hassle-free to use and affordable product
- Pushpin not as durable as others
- The handle may be small for some people
11. QKURT Bicycle Chain Tool Kit
People accustomed to using a Shimano chain tool will appreciate the remarkable design and craftsmanship of the QKURT Bicycle Chain Tool Kit. It may not be popular, but it can do an excellent job repairing broken bike chain links without spending a lot.
I admire this bike chain breaker’s thoughtful design and dependable construction. I feel confident using the breaker to snap the pegs from my bike chain. Assessing a bicycle’s chain wear is also effortless because of the included chain gauge. Determining if I need to replace my chain altogether becomes an easy task with this simple device.
I love the pushpin’s unique design. It has a narrow thimble for pushing the peg out of its slot and an expansive threaded base for better stability. The engineering ensures the thimble will never break. Maybe that is why the company decided not to put an extra pushpin in the package.
Handling the tools is solid and secure. They do not slip from the hand. The lever has a nice heft that guarantees better leverage, freeing users from using excessive force. One can repair the chain links of almost any bicycle on the market, including single-speed systems and bikes with 7-speed to 11-speed groupsets.Heads-up: I wish the brand included a link plier to go with its chain breaker.
- Compatible with multi- and single-speed chains
- Unique, more durable pushpin design
- Complete with chain gauge
- Available at an inexpensive price tag
- No chain pin stripper
12. KZNANZN Detacher Breaker Cutter
The KZNANZN Detacher Breaker Cutter is an excellent roller chain breaker tool for bicycles, motorcycles, all-terrain vehicles, go-karts, and other vehicles with chain drive systems. It has reliable construction and a price that many people will never pass on.
Using this tool is as easy as placing the chain on the device’s jaws and tightening the lever until the peg pops out at the other side. The handles are surprisingly longer than what other products provide, ensuring bikers will never break a sweat when removing and replacing their bike chains.
I appreciate the company’s efforts to strengthen the tool by using only high-carbon steel and reinforcing it with compound-strengthening materials. The pushpin also has substantial composition upgrades, undergoing extensive heat treatment and hardening before mating to the tool.
The process should make the chain breaker less friendly on the pocket, but it is not. This handy tool is more affordable than products that only work with bicycle chains. It works with roller chains sizes #25 to #60. The chain breaker also extends its usefulness to other roller chain types, ensuring adequate coverage of different bicycle groupsets.Heads-up: While this motorcycle chain breaker tool can accommodate various chain sizes, some users complained that it does not work with chains smaller than #40. It pushes the peg straight out of the plates but gets stuck upon reaching the chain’s opposite side. Moreover, some people do not agree with its looks.
- Compatible with different vehicles with chain drives
- Reliable construction with extra-strength, heavy-duty pushpin
- Effortless operation thanks to the long handles
- Great value for a pocket-friendly, lightweight product
- Not ideal for small-sized chains
- Unappealing design
What to Look for When Buying Chain Breaker Tools
A bicycle chain breaker tool is a simple device that helps people remove the metal pin connecting two bike chain links. It may seem a straightforward process, but the inherent chain design makes rivet removal difficult without the correct tool. That is why it is best for bicycle owners to have a chain breaker in their toolbox.
Here are some of the factors one must consider when buying a chain breaker.
Although chain breakers perform the same function, no single product can accommodate all bike chain sizes and groupset types. Most products can only sit several sizes of bike chains on the breaker block or shelf.
For example, a chain breaker may only accept Shimano and SRAM groupsets, but not Campagnolo speed chains. The reason here is that Campagnolo chains have a greater width than the two other systems. Hence, a Shimano 12-speed may already be equivalent to a Campagnolo 11-speed, give or take a few millimeters. Some products also accommodate a 12-speed chain, but not an 11-speed.
That is why buyers must read the product specifications carefully, ensuring it is compatible with their bicycle’s chain system. Otherwise, they will only waste money on something they will not use.
Ease of Use
A chain breaker’s ease of operation is a function of its design. A well-crafted and thoughtfully designed chain breaker will make it effortless to use.
For instance, the handle’s grip and lever length are two crucial factors determining a chain breaker’s hassle-free operation. The handle must be comfortable to hold and not slip off the hand. Meanwhile, the lever must be sufficiently long to reduce the force required to turn the pushpin through the chainplates and peg.
It would also be great if the chain breaker has a groove for checking how far the pushpin has advanced through the slot.
In general, an all-metal construction guarantees durability and strength. Unfortunately, these products are often heavy and unwieldy. On the other hand, alloys provide an excellent balance between lightweight and strength. Some products also come with aluminum construction, while others feature high-carbon steel.
We recommend researching the pros and cons of each material to help buyers decide which product is best for them. Buyers must know that high-density, high-quality materials often command a high price.
Chain breaker manufacturers continue to outdo each other by adding excellent features to their products. It would be wise to examine each extra attribute to determine if it adds value to the purchase.
For example, some products come with other bike chain repair tools, such as a chain gauge, link plier, hook, bonus pushpins, and extra chain links. Companies can also integrate more subtle features in their products, including a ring or carabiner slot and a hidden compartment for small tools.
Others may design their chain breakers with a secondary shelf for loosening super-tight chains.
Several factors can determine a chain breaker’s price. For instance, some online retailers offer exceptional discounts to entice customers. Amazon and leading e-commerce sites are always available to give customers a great bargain.
Location can also impact a chain breaker’s price. For example, if Canadians want to buy a chain breaker tool Canadian Tire will be a no-brainer.
It would be best to check the product’s construction, compatibility, ease of use, and extra features to assess its overall value against the price.
Are All Chain Breakers the Same
All chain breakers are the same because they serve the same purpose – push the metal pin or rivet that connects two pairs of outer and inner plates that form a single chain link. This tool can also drive a new chain pin or when replacing the chainplates.
While the function is the same across all chain breaker types, they differ in their rivet size compatibility, pin design, tool size, price, and inherent features. For example, a 5-speed chain is wider than a 7-speed chain.
That is why bicycle owners must have excellent knowledge of their bike’s chaining before shopping for a bike chain breaker tool.
Do I Need a Chain Breaker Tool
A chain breaker tool is a must-have for any bicycle owner or anyone who has a vehicle with a chain drivetrain.
While it is possible to disconnect the links without special tools, the process can be intimidating. There is also the risk of damaging the chain, prompting the owner to buy a new one.
How Do You Break a Chain Without a Tool
It is possible to break a chain without a tool using three things: a solid block with a small hole for positioning the chain link, a thin nail for pushing the chain rivet without getting lodged into the plates, and a hammer for driving the nail.
Place the chain link on a solid block, preferably a small nut, ensuring the rivet is over the nut’s hole. The hole must be big enough for the pin to pass through but small enough to prevent the plates from bending.
Position the nail on the chain pin’s flat surface before hammering it down. It would be best to carefully tap the rivet until it comes out on the opposite side. However, be cautious not to push the pin too much so that it falls off. It should still connect to the other side’s outer chainplate.
Slowly wiggle the chain to free it from its connection.
The best chain breaker tool is perfect for repairing broken bike chains and other essential components. It fits the chain specific to a person’s bicycle groupset. The tool is also sturdy, reliable, durable, and effortless to use.
While not necessary, it would be best if the device also features other functions, such as a chain pin breaker, chain gauge, hook, and chain link pliers.
