How To Repair A Chain Using Quick Link
Chain quick links, connecting links, missing links, chief links – any y'all call them, they're fast condign the mutual way to join a chain.
As one of the smallest components of a cycle, quick links all but remove the run a risk of wrongdoing and open upwardly possibilities of removing a concatenation for thorough cleaning, pedantic travel or nerdy lubrication. For years KMC, YBN, SRAM and Wippermann accept used such links, while Shimano and Campagnolo held out and stuck with special replacement pins. Even so, even Shimano is at present changing its tune and its latest 11 and 12 speed chains are bachelor with master links.
CyclingTips tech author Dave Rome reveals how to use quick links, which are best, whether you tin re-utilise them and what tools are worth owning.
How a quick link works
A concatenation is made upwardly of a series of interlinking and alternating wide and narrow plates. Each plate is held together with a pin, or rivet, and the inner links of the chain articulate around this connecting indicate. A quick link works by replacing i "outer" chain link with a pair of slotted interlocking outer plates that feature permanently prepare pins. The force applied to a chain pulls these two opposing links into a closed position. Squeezing the links together (with enough force) volition meet the link come up undone, which is why information technology's as well commonly called a quick release chain link.
Unlike joining a chain with a concatenation pin and a concatenation breaker, master links offers a solution that's more resistant to human error. Similarly, quick links open up the possibilities of cleaning (or lubricating) the chain off the bike, whereas breaking a chain by driving out a pin creates a weak spot, and and then chains installed with a pin are best left on until worn (or alternatively, install a master link!).
How to install a quick link
Installing a quick link is relatively easy, merely there are a few things to pay attention to. The video above details the basics, with directions provided below, too.
ane. Ensure your chain is the right length and that both ends of the concatenation are open inner links, (using a chain billow) every bit needed.
2. Insert the links through the chain's open ends so they oppose each other.
3. Sit the pins of each link into the larger slots of the opposing link. Ensure both sides of the link are engaged with each other (failing to practice this will mean the link is unsafe to ride).
4. Yous can now pull the link into its closed position. If using an viii or 9-speed link, you can now simply pull the link close with your hands, although you may need to squeeze the link together at the same time.
5. Newer 10, eleven or 12-speed links have progressively go tighter and I've found the use of tools profoundly eases the installation process. Squeezing the link together between your fingers often eases the procedure and this is but possible when using the proper tools. Await for tools that utilize outward pressure level with leverage – KMC and Shimano offer such tools, but few others do. Simply insert these pliers into the rollers of the link and clasp and the link clicks into place.
6. While I prefer to use tools, connecting a tough link can be done without tools. With the link semi-connected, pedal the chain to be centered higher up the chainstay. Hold the rear cycle (by the tyre) with i hand, and apply firm pressure onto the pedal in a clockwise direction with the other. This strength will aid spread the chain and close the link. A pop or click should be heard if you're successful. Inspect the concatenation to ensure the pins are fully seated.
7. If pace six is unsuccessful, and then rest the bike on the basis. Ensure concatenation link is centered in a higher place the chainstay, firmly use rear brake and stand up on bulldoze side pedal. Button down until the link seats.
Note: Wippermann has a unique re-usable "Connex" link that does not require whatsoever force to shut. See our video higher up or Wippermann's instructions for correct utilize.
How to remove a quick link
Removing a quick link is just a matter of reversing the process of installing information technology, even so, newer x and specially eleven/12 speed links are locked into position and require meaning forcefulness for removal. Most newer quick links are designed equally a one-utilise item, and so re-opening them volition weaken the locking part. I embrace this in more than detail later.
If dealing with an older 8 or ix speed link, then squeeze the two plates of the link together and slides them toward each other. Grit inside the chain can brand this process catchy and so a little wiggling may exist needed.
For 10, xi or 12-speed links, yous'll need to employ tools to open up the link. If you lot program on replacing the chain and don't take the tools to undo the link, you can use a chain breaker on whatever chain pin other than the master link to remove the chain.
When using the advisable tool, simply insert the tool into the nearest rollers and squeeze the handles. This volition pull the link together and undo the quick link.
If y'all don't have this tool, so in that location are two hacks. First is to use a combination grip or needle nose plier, place the jaws of the tool on opposing diagonal edges of the quick link and squeeze. This method will probable damage the quick link and and then replacement is strongly recommended. The second choice is to use a thick string or string, wrapping information technology in your hands and pulling it in opposing diagonal directions. This is a expert hack for some chain links, withal, it's not suitable for extremely tight links such as Shimano'south SM-CN900, where you'll likely cut your hands due to the strength required.
Note: Again, Wippermann links are re-usable and practise not require tools to utilise install or remove.
Mixing and matching quick links
Mixing and matching quick links is no new feat, and riders have washed so successfully from the days of eight-speed drivetrains. Much of the need for mixing comes from Shimano and Campagnolo'southward commitment to replacement pins as a joining method.
As it turns out, while chain brands certainly wouldn't recommend any mixing and matching and I do believe it's safest to stick with the right brand link, information technology'southward typically no problem to exercise so.
Those with older 8 or nine-speed chains should discover success with using KMC, SRAM or Wippermann links on just almost any concatenation of the same speed.
Ten-speed users can also openly mix and match betwixt 10-speed chain manufacturers and ten-speed quick links. However, do beware that Campagnolo x-speed chains are narrower and require specific links, something offered by both KMC and Wippermann.
For xi-speed I tested all the popular links on the market and found there to be total cross-compatibility, including with Campagnolo bondage. However, what'due south somewhat unusual is that the outside widths of connecting links do vary.
Wippermann is marginally wider than the rest. My (cursory) testing of the Wippermann links showed they worked also as the other links, and I got similar successful reports from other riders and mechanics. Nonetheless, do be aware that they're the only link that doesn't "lock" into position, and and so a freak dropped chain, chain suck or similar may see the link dislodge. And while I previously experienced some weird ticking noises with Wippermann links on x-speed chains, I couldn't notice such issues with 11-speed.
Professional person mechanic Win Allen, owner of Wins Wheels, uses quick links on a daily basis. "In the shop we use the KMC links for Campy and Shimano, SRAM nosotros only use SRAM links," he said. "Now that Shimano is supplying 11 and 12-speed bondage with quick links we merely utilise Shimano links on those chains. The residual are withal getting the KMC links. I've never found the demand to mix and lucifer since we e'er have the right brand links in stock and my preference is to proceed brands together."
It'southward still too early on to tell about absolute cross-compatibility for newer 12-speed links, notwithstanding, Adam Kerin of Zero Friction Cycling suggests he has customers using SRAM Eagle 12-speed links (a mount bicycle product) with Campagnolo 12-speed chains without event. According to Kerin, "SRAM Eagle chains are v.26mm wide, Campagnolo 12-speed are 5.15mm, seems the 0.11mm deviation is fine."
Reusing quick links and which ones to buy
I used to recycle my 9-speed links from concatenation to chain without effect. When article of clothing would appear on the pins of the master link, I'd supervene upon them, merely would otherwise remove the chain freely from the cycle until that point.
Withal, when SRAM introduced its 10-speed quick link, it had articulate instructions not to reuse them. They were a one-shot detail. Opening the link would burr the locking tab off the link and in the best case it would become less secure, worst case, it could crusade a stress point. I'd tempt fate and reuse them anyway on my ain bikes, and always without result, only I'd never exercise that to a client's bicycle. After all, a broken concatenation can be a very dangerous thing.
Newer 11 and 12-speed links are much the same as those 10-speed links, and most are designed to be closed once. Shimano, SRAM and KMC (ane variant) sit down in the "not-reusable" corner and recommend replacement if removed. However, in that location are endless reports of people who have successfully reused these links without issue, myself included. If you're willing to chance it, then pay close attention to the forcefulness required to install the link. As Win Allen suggests, "I accept reused the Shimano link with much success, but simply if it however has a tight fit when re-installing it. If there is any question information technology gets replaced."
Vincent Gee, a old WorldTour mechanic, and at present head mechanic with American team Aevolo, is another who loves the tight snap of Shimano'southward new link. "[While] non-scientific, I practice like the heavy snap/engagement of the Shimano Quick link over the SRAM version. With SRAM I tin can simply agree the wheel and utilize pressure to the crank with my hand to close information technology while the bike is in my piece of work stand. With the Shimano version, I can do the higher up method sometimes. And sometimes I have to gear up the bike on the ground and step on the pedal to shut it."
For those looking to regularly reuse a quick link, mayhap for detailed chain cleaning or submersion waxing, then I'd suggest either replacing your quick link every second to third use to play it safe. I've found that the closing force is noticeably reduced by the 4th or fifth use on Shimano, SRAM or KMC links. Alternatively, cull a reusable quick link.
A fiddling-known fact is that KMC offers both reusable and non-reusable quick links for 10 and 11-speed chains. The packaging will particular which is which, or otherwise, a close look at the link itself will tell you what you're dealing with. Annoyingly, most sellers of these links don't specify what they're selling. Practise beware that similar replacement rules apply to the reusable KMC links, and one time they terminate requiring force to close, you should replace them. KMC suggests they are merely skillful for 2-3 uses. Additionally, while KMC suggests its not-reusable links piece of work with Campagnolo chains, they unusually propose otherwise for the reusable model – I reached out to KMC for an explanation on this just haven't heard back.
A swell-value option is YBN. These links are extremely similar to the KMC Missing link and are claimed to be skilful for upwardly to v uses. Compulsive chain and chain lube tester Adam Kerin of Cipher Friction Cycling says he typically reuses his YBN links 5-10 times, and without outcome to appointment.
An culling to these KMC and YBN links are the Wippermann Connex links. These unique links are easily reusable many times over without the need for tools at all, instead relying on a special extended shape that can simply open with the corresponding outer chain plates articulated out of the way.
Of the links I've used, I've constitute very little difference in quality or reason to choose one over another. My preference is to play it prophylactic and stick with the chain manufacturer's specified link and supplant it as soon as the closing or opening force reduces.
If you plan on taking the concatenation on and off the cycle semi-regularly, then I'd recommend either the YBN or KMC reusable links. The Wippermann Connex is some other strong option; they're piece of cake to utilize and seemingly work merely fine, but I don't love that they're a hair wider, longer in length and an odd shape.
The best Quick link chain pliers
While Wippermann Connex and just about all eight and nine-speed links can be removed by manus, the rest require an element (or a lot!) of forcefulness. A dedicated tool is worth owning if you lot program on re-using a link.
Merely virtually every tool brand offers a chief link plier and they all do much the same role and in the same mode. They simply claw into the rollers of the chain and work to clasp the chief link open up.
Some models feature outside grooves to help pull the rollers apart and shut a link, however, pulling plier handles away from each other is awkward and lacks mechanical advantage. Such a "closing" feature is almost pointless with tight links. Yet, there are exceptions.
Shimano's TL-CN10 tool is by far and away the best available, simply because information technology works to open and close links with a leverage advantage. This a huge asset when dealing with tight links, and no other tool I tested has this characteristic (annotation: It seems this tool is sourced from Super-B, who too offer such a tool, albeit with simpler handles. And X-Tools as well now offer a version of this). KMC comes close, in that it'south the but other tool to offer a squeezing action in closing a link, however, it's a separate tool to the link opening version and so yous'll need to purchase 2 tools to exercise what the Shimano achieves in ane.
After Shimano, in that location's not much to separate the remainder, and many are clearly from the same manufacturing plant. Made in Europe, Unior's tool is the highest quality, but tin can't be used to close links. The thick handles of BBB and Park Tool, meanwhile, offer the comfiest usage. X-Tools (old version) was the cheapest tested and does the job, but the handles tin likewise get stuck on each other, then be warned.
Given how similar these tools are, I'd propose deciding on whether you lot want the tool to aid close the link or if you'd rather do that task sans tools. If it'due south the latter, pretty much every quick link tool on the market will work for dwelling use and I'd but suggest picking your favourite brand, colour or the all-time-priced option.
If you're interested in something to take with you on a ride or stash in a small travel kit, then both Wolf Molar Components and Clever Standard offer suitable products. Clever Standard'south product (also sold past KMC and a few other brands) is 2 tyre levers that inter-link to make a functional primary link plier. Do beware that the reinforced plastic won't stand up to regular use in a workshop, but it'll suffice for occasional apply. Every bit previously reviewed, the USA-made Wolf Tooth Pack Pliers are in a unlike league, and include storage space for spare links, a valve cadre tool and a tyre lever into an impressively small parcel. The Wolf Tooth pack pliers aren't comfortable (or piece of cake) to employ on super tight links, but they'll do the task in a pinch and durability isn't a concern.
Linking it all together
As it turns out, information technology'south hard to get wrong with quick link or tool choice. There are nuisances, but there'due south little to fear with these tiny components. To play it safe, the full general advice and official company line is to stick with the chain and connecting method that your drivetrain manufacturer recommends. However, if you choose to listen this advice, it seems your options are plentiful.
Reusing any concatenation quick link against the communication of the manufacturer is done at your ain risk.
