40. How to Use a Quick Release Chain Link

Shows how to disconnect and reconnect two of the most common quick release chain links.

IMPORTANT: Nuts and bolts on your bike should always be tightened to the manufacturer's specifications.

Today we’ll learn how to use a quick release chain link. There are two common link types, for which all you need is a good set of pliers.

Type 1

The first type of quick release link is found on bmx and single speed chains. There are three parts: one link plate with two chain pins attached, a plate with no chain pins that slides on the other side, and a clip that holds the link together once installed.

Disconnect Type 1

To disconnect this type of link, place one jaw of your pliers on the chain pin, and the other jaw on the open end of the clip. Then squeeze your pliers until the clip pops off. Then you can remove the outer plate and slide out the rest of the link.

Reconnect Type 1

To reconnect, simply reverse the process: slide in the link with the chain pins, place the outer plate on the other side, and then put the clip back in place. This time place one jaw of your pliers on the closed end of the clip, and the other jaw on the opposing chain pin. Then squeeze them together until the clip snaps into place.

Type 2

The second type of quick release link is found on multi-speed chains. There are only two parts to this style. Each of the two plates are identical, and each has a chain pin on one end.

Disconnect Type 2

To disconnect this style, simply place the pliers on opposing ends of the link as demonstrated, and then squeeze the pliers together until you hear a click. Now you can slide both links out.

Reconnect Type 2

To reconnect this type you don’t even need any tools. Simply slide both ends of the link together and then rotate your chain on the bike until the quick release is on top and the pedal is facing forward. With both wheels on the ground, compress your brakes so your bike doesn’t move. Then step down on the pedal. It doesn’t take that much pressure to pull the links so they snap into place.

05/14 Back Sprockets Break Loose Under Load

I have a Shimano Hyper 7005 Series bicycle that has an issue in the back wheel. Under load (simple acceleration), the back sprockets seem to break loose. The chain is not jumping, the gear cluster spins with the chain, but the cluster doesn't seem to catch the wheel. Sorry if my terminology is wrong; I don't know that much about maintenance (hence my question online). It's so bad, I can spin by hand to get it to break loose. And guidance toward diagnosing and repairing would be greatly appreciated. THANKS!!!... Read more >>

05/07 SRAM and Shimano compatibility

Hiya all, I'm a newbie here. Just started on the hobby of repairing/rebuilding bikes. I like fixing them more than I enjoy riding them. Go figure. I have about 16 bikes in various condition and am currently repairing 3-5 of them, switching from one to another as I wait for parts and research. I usually work outside my garage (car garage, not a workshop) and have quite a number of passerbys ask questions and for help. I do not charge anything except if I have to buy spare parts for them. I repair their bikes gratis, if I can figure out what the problem is and if it's not too major a task. I wou... Read more >>

04/23 Cracked chainring on a beater

Hi I just bought an old commuter (2000 marin kentfield). The middle chain ring is beat up, cracked like this in three places: I test rode it, the chain doesn't slip off, and the teeth seems to stay in place. How long can I ride this before it breaks, do you think? I dont have the tools to fix it, and having a repair shop do it in Toronto would mean I might as well buy a new one. When I do get my hands on a crankpull I will attempt a repair... in the meantime, I'm going to clean it up, lube and ride. Just wonder how far I can go?... Read more >>

04/19 Need new parts!

Hey everyone!, I'm new to the site but it looks like it is a pretty good site. I have a 2002 Trek Fuel 90 that has the original Crankset, rear cassette, and chain on it and I am looking to replace them because many of the teeth are either really worn or broken and the derailer is skipping gears quite a bit. I already had the derailer adjusted at the beginning of last season and I don't think that is really the reason why it is skipping. My issue is the following: I was going to just replace the chainrings on the crank but it came with a Bontrager Comp 44/32/22 and I can't seem to find an... Read more >>

04/16 Bike Novice - Need New Cassette

Hello all, A quick Google search popped up this website and you guys all looked to be very friendly. So, I have a Giant bike, about 7 years old, and the cassette and chain are both... bad. Really bad. Rusted, gears worn off, stiff link... it's bad. I already bought a new chain at the local bike shop (SRAM PC 850) but then realized I needed a new cassette too. So, buying a new cassette looks to be much more difficult than chains. My bike is a 2004 Giant Rincon. Image 1 Image 2 Do you guys have recommendations on what cassette I should get? I need the front three gears and the re... Read more >>

04/06 Changing cog set

Hi, I have a road bike with shimano 105 10 speed drivetrain. My cog set is 12-27. I would like to change my cog set to 11-32. I know this would be a MTB cog, probably the Shimano XT CS M771. Its a 10 speed with the 11-32 cog but learned it is the mountain bike equivalent of Ultegra. My question is, can I use my original 105 derailleur, chain, shifters, etc. for this change. I have had 2 suggestions from friends: 1) put the cog on and try using the rest of the original set up and see if the shifting is smooth....if not, get a medium cage Shimano Ultegra RD 6700 that they said will work with th...

04/05 Replacement chainring?

Hello! Having trouble trying to find a replacement chainring for my bike. It's just the middle ring that's worn so trying to replace only that. It's a shimano SG chainring, 36 teeth, 5 bolts with a BCD of 110mm. On an 8spd bike. Been to a local bike shop and they got me a 36 tooth, 5 bolt 110 BCD. But it didn't work as it was thinner and the chainring bolts stuck out somewhat and got in the way of the chain. I normally get stuff off Chain Reaction Cycles (I'm based in the UK) - http://www.chainreactioncycles.com/ - But couldn't see anything that might match?! Any help, much appreciate... Read more >>

03/26 Chainset/crankset

Hi there, Massively new to biking, and am undertaking a massive 1000 mile charity bike ride in the summer. I have myself a lovely new road bike, and have managed to damage the crank arm and chain ring, looking to replace them all. I currently have a Truvativ Iso Flow 39/52, not looking to spend too much money, but one something as good if not better for around £50. I have found RaceFace Cadence Road Chainset 39/53 - is this too big? i don't understand about the ratio's at all! If you have any suggestions of better, or more suitable chainsets, please let me know. Really want to get bac... Read more >>

03/19 Bicycle falls apart while bicycling

Hello! My bicycle broke. I mean that as in when I pedal the chain falls apart. It just happened on a routine bicycling trip when suddenly bang! Something went flying off the gears or something. I know something is missing but I can't figure out what. Thanks for any help you guys can provide. Attached is a pic of the place I think is trouble.... Read more >>

03/15 Front Chain Ring Guard/Cover/Shield?

I have an old Specialized Mountain Bike. 7 speed cassette, 3 front chain rings, the largest is 42Tooth, just under 7" across. I have thrashed my inner ankles so badly from previous injuries that scrapes from the front chainring are excruciatingly annoying & painful. Any ideas about a cheap way to put some kind of guard on it? Seems to have 4 un-threaded holes Would a guard mount to where the chain ring mounts or use those outer holes? A close up of the outer holes. I know this seems like a lame question, and I know most people toss the guards ... Read more >>

03/09 Rear Cassette wobble

First of I'd like to say hello! I'm come to this forum quite often but have only just signed up and am happy to be here. Wonderful site. My rear cassette wobbles when my rear wheel turns. The wobble speed and the rotation speed of the wheel are synced - one revolution per wobble. It's pretty bad. When I'm peddling hard it jumps gears back and forth quite quickly which no doubt is very unpleasant. What is the actual issue here? The cassette? The rear hub? Any help on a solution or what I should be looking at replacing would be great. Thanks a bunch! - Ratchet... Read more >>

03/07 Chain slips

I have a problem with my chain slips when pedaling hard. This only happens when the chain is on the middle chainring. I have a new chain, cassette, and derailer and the mechanic at the shop says the chainring doesn't look bad and He just re adjusted the rear derailer. This did not help. Could it be because my crankset is a nine speed and my cassette is only eight? Or could it be a crappy deraihler. maybe the guy at the shop doesn't know as much as i thought and it is the chainring causing it.... Read more >>

03/02 Newbie - broke my chain, need help

I was out riding yesterday and about 15 miles out my chain snapped. I looked at it and it looks like it's at a spot where it's silver and newer looking, not like the other darker colored spots. Also it's a "taya" chain. It pretty much just looks like it snapped and the metal piece was bent. It's a pretty old 10 speed bike (two sprockets on front, 5 on back) and I don't think I'll be able to get a new chain without it slipping a ton, and then having to get a new back sprocket (this bike isn't even worth as much as a new sprocket). So I was thinking if I got a chain link and chain tool, I could ... Read more >>

03/02 Chainring compatibility question

Anyone have any info/advice about aftermarket chainrings on a Shimano Deore XT FC-M737, five-arm 94-58 bcd crank? I would like to increase the gearing from the 42-32-22 to 44-34-24 or 46-36-26. There are some Shimano chainrings out there, but they are expensive. Will I have problems installing BBB, FSA, or some other brand chainrings on the Shimano crank? I have always used the same brand for replacement parts to keep installation and operational problems to a minimum, and have no idea if they would fit and work properly.... Read more >>

02/28 Upgrade: BB, Cassette, chain, chainrings & crankset

Hey all, I have an old (around the year 2000) Trek 1000 road bike. The chain, chainrings and rear cassette are long overdue for replacement. I want to replace the crankset and bottom bracket while I'm at it too. I know the current drivetrain has 53T/39T chainrings, and an 8 speed 12-24T cassette. the label Shimano SORA appears on front and rear derailuers My budget is around $300 Australian (roughly the same US), but I'm getting confused with what compatibility issues I might run into, so these are the things I'm trying to clarify: 1. BB & Crankset compatibility: because I'm... Read more >>
