- Threadlock, or retaining compound, can be found on most bolts on your bicycle. It adds a bit more security to important bolts on your brakes, handlebars, and elsewhere, to ensure they remain tight enough to keep you riding safely. In this video, Alex talks you through threadlock, where you need to use it, and how it actually works.

Do you use threadlock? Will you start using it after watching this video? Let us know 👇
No. See no reason. I have never experienced a bolt going loose. I think this is overkill, and just add to the annoyance of getting them off.
Gcn tech, can you guys make another series of bike builds? May I suggest mtb to gravel bike build please 🙏. For those people wanting to dip their toes on transitioning from mtb to road but act on low budget. A huge thanks in advance 😂.

Firstly, red threadlock has no place on bicycle components unless you never want to ever disassemble it, even with heat.
Yes, threadlock has replaced anti-seize. Even though anti-seize walks less than grease, but sometimes you just don't want that near rotors or bearing surfaces.
The purple thread lock inside a red bottle is really confusing! Yes I did see the purple on the label..
... and the "purple threadlocker" itself is blue 🤯. I was surprised (and somewhat worried) the first time I removed the disc calipers of my LBS-assembled bike and saw red threadlocker, until I applied my own local-brand medium-strength threadlocker and saw it was red. Loctite threadlocker bottles also have that "feature" (being mostly red with a stripe marking the type of threadlocker)
It's not as simple as it could be, that's for sure!
@@docontra4921 loctite threadlockers come in red bottles but the liquid's colour matches the labels:
222 = low = purple-ish-pink,
242,243,248 = medium = blue,
262,268,271,272 = permanent = red
PS if you live near the sea, forget about alu nipples, not worth it, go with brass
@@docontra4921 if it were the high strength red, you wouldn't be removing those calipers.
Thanks guys. Seeing as how I've serviced the head set on both my roadie and mtb lately, it might be worth taking the screws out again and applying some...
That what it is. I was wondering about that. Thank you.
You only need purple for bikes. The point of having a thread locking system is to keep the preload in stud/bolt (that can be lowered by bolt loosening) and NOT to counter any additional torque put onto it: i.e. if a bolt rating torque is 5Nm, you don't want to have to use an extra 5Nm to unlock it. Bolts loosen because of changing conditions (eg pushing on the handlebars from side to side) and vibrations. A good design takes into account the bolt preload (example of 5Nm) and does not take into account the thread lock. the added lock is just for safety!
You guy's have birds on set. I approve. =-B (Presumeably you're sitting in front of a green screen at home lol...)
Alex is sitting in his garage workshop - there’s a video about it
Very excellent
Would have liked a list of components you would recommend to use this on. You really didnt answer the question
Be careful with the really strong threadlocker.. some types need intense heat to release! Might not be so happy using a blow torch on a carbon frame 😱
Man if you would have released this video a month earlier, my valve cores kept coming lose when using a lezyne minipump. I got fed up with and had some good quality liqui moly red thread lock laying around, I used that on them. Its gone be fun to remove them when its time to refresh the tubeless sealant.
Oh…you also have this problem with the Lezyne pump?! Thought it was just me!!

#askgcn - co2 cartridges
Hi GCN I am looking to upgrade my road, emergency tire kit. Currently I have a minipump which isn't exactly massive (16cm) but I don't want to attach it to the frame. Handlebar bag is an option, but I want a smaller setup for climbing days. The pump won't fit in a saddle bag so I started looking at co2. It's promising but I don't like the single use disposable nature of them. So my question is, what are the alternatives? Refill cartridges? Or are they not as bad for the environment as I think? What do you guys usually carry in a saddle bag?
Interesting video. Thanks! If I use it on clean threads, without grease, how can I prevent seizing?
It wont.
This threat lock can i use for fixed gear cog?
Hi!
Wich disc brake are lighter than shimano ultegra???? Thanks
Im kinda confused because my new raceface Atlas stem (handelbar clamp) came with the screws greased instead with threadlock... So should I clean it and apply threadlock instead???
My old raceface Turbine r 35 stem had threadlock on it.
Just curious, Alex, why your great looking Orbea is using a Ultegra crankset and not Dura Ace?
Early on I was always told to use grease on the various bolts in order to ensure proper torque and prevent seizing later on. How do greasing the bolts fit in with threadlock these days? Mutually exclusive?
Threadlock prevents seizing by corrosion
Nice torque tool. Does it adjust to various torque settings ?
Can I use Loctite 243 with plastic bolt ? thanks
awesome

Lol. I’ve had a bottle cage rattled rattled off by the cobbles of Lincoln Michaelgate. Threadlock on bottle cage bolts solved that.
yep, def worth a dab
split-lock washers do the trick as well, they cost a few cents and threadlocker is a bit pricey. Bottle cages are the most notorious thing to vibrate loose next to disc brake calipers/rotors
Thread locker would've saved me from drilling my rusted out bottle cage bolts...
@@robertcowling4313 I never use anti-seize on bolts. You use that on stuff that's meant to be in constant motion, not bolts.
Loctite would've prevented my bottle cage bolts from corroding.
what brand of torque wrench do you use?
I just lost a dust cap from 1991 8spd Campy Record derailleur pulley -the whole pulley wheel fell off. I found the scattered parts except for one dust cap, which is unique and impossible to find online, so I replaced the wheel with an 11-tooth generic (works fine), but this could have been avoided by a) checking my bike better, b) threadlock!! I'm going to use it on some parts that don't normally have it, just for peace of mind.
With the low torque settings on cycling bolts, could you explain why carbon assembly paste can be the difference between a slipping or unlocking component like a carbon handlebar stem / clamp and a seat stay / clamp.
Beacuse the paste creates friction
I used threadlock on the pegs of my MTB pedals. Haven't lost one yet.
Do you have a sizing chart ?
I've got an old road bike that has a history of the fixed cup on the bottom bracket coming loose, even after tightening it down with a lot of force. The style bottom bracket is a typical 3 piece, tapered & cotterless used on many bikes from the '80's. Would the threadlock do the trick to keep the fixed cup from coming loose? I'm worried that during it's initial use, some of the excess threadlock might seep into the cup & bearings - a real disaster!!
What’s the torque wrench he uses at the end?
Any tips on cleaning the inside of threads, the nut part of the nut and bolt? Cleaning the bolt side is easy, but the thread that it goes into is a lot harder.
A thread cutter usually works
Can you apply treadlock to bike spokes so the wheel remaine straight forever ( no more wobble in the wheel)
There is also an activator you can use to speed things up.
As stated, thread lock keep things from undoing by itself. You CAN undo them with a tool. Thank you.
Gotta be honest I don't use thread lock, I actually use grease on almost everything on the bike because I'm afraid of the bolts seizing up... thread lock on bikes just gives me nightmares.
Same. Only grease and I have never had a single component loosen. That being said, I maintain my bike constantly, so I could see it being more of an issue for those riders who either don't know how to maintain their own bike or rarely do ... in which case, this video is not for them.
My worry with grease on low torque areas is that you can achieve more compression with the same torque - so you could end up crushing something whilst your torque wrench says you haven't overtightened. At least that's what it feels like when I use grease for those things.
@MRGRUMPY53 I put some centrelock disc rotors on the other day - with a tiny bit of grease. As I was using a tool that takes a spanner I couldn't put a torque wrench on it. No idea if they're on too tight or too loose. Or Goldilocks. What does 40nm feel like in terms of grunts or effort?
@MRGRUMPY53 No. Those bolts are about 6nm. So I'm looking for 6 - 7 times that force. Just did it up shy of what stripping the threads might feel like.
On rough surfaces which cause vibration any clamp / bolt etc. can come loose. Thread lock works by filling the spaces between the threads, not allowing vibration to cause movement between the two items fastened together and thus allowing them to untighten.
It might be worth mentioning that the bottle should be shaken thoroughly before using.
Nice one!👍.
You need apply thread lock on bottle cage bolts. They constantly under stress.
Oli likes to talk about how to make things loose and Alex likes to talk about how to make things tight. Perfect
Initially I read "Oil likes to talk about how to make things lose..."
Could you pleace add english automatic subtitles as well?
🎉🎉🎉
Hmmm... the manual for my Specialized bike is recommending green on most parts. Kind of weird.
huh... I always used grease for these bolts. Is there any reason that threadlock works much better?
IMO Works better when required torque is under 2nm. I use it only for jockey wheels bolts and computer mount bolt , maybe also for bottle cages is good.
The motivation for using thread lock is diametrically opposite to that for using grease. With threadlock, the goal is to keep the two parts attached to one another. With grease, the goal is to allow the parts to be separated next time something needs service. As a person who removes the pedals, bottle cages, bars and rear derailleur when packing the bike for air travel (not doing much of that these days though), I like components to disassemble easily. If you have ever sheered off a bolt head due to bi-metalic corrosion (Aluminum/steel), you would diligently grease your parts for future disassembly.
Those brake pads on the front wheel look dangerous :P
Could I replace threadlocker with plumbers tape?
Plumbers tape is intended to keep a water seal for plumbing joints which rely on the thread for a seal (rather than compression joints) it's main job isn't keeping something secure. Bike bolts would be subject to alot more rattling, shakes etc. to work loose over time. However plumbers tape would fill up the gaps inbetween the thread and might slow down the unwinding process.
One important place for thread lock is not on the bicycle. Use it on the screws that hold the cleats on your shoes. Those screws are notorious for getting loose or coming off while you are riding. If thread lock isn't immediately available, fingernail polish works quite well...the color of the polish won't matter.
wow, yeah one of my shoes come loose unexpectedly after a whole year of doing fine, but that time i need to remove the pedal and damage the shoes slightly initially (try to remove the shoe realizing after it does not work). lesson learned.
Shake bottle before every use
Heat component for instant cure (when needed)
3:00 First time seeing rust on gcn
I used it in a bus for special trips
There is NOT a bike component needs threadlocking. The only thing I use it is building a suicide fixie, to attach the cog to a threaded, non-fixie hub.
I disagree with this a ton! I just purchased a 2500 ebike. Wanted to swap pedals went to un thread a pedal and book Crack thread is ruined. So now I can't install new pedals and new crank arms the shop is telling me going to a min100..... never ever have I heard of this. I've only ever heard of using grease
Funny never used thread lock in 25 years except bottle cage bolts
Mentioning break-loose torques without reference to thread size? Srsly?
Do you have a budgie?
*Thread lock*
Is something I've started using on rear axle repairs, and lose lock rings.
Including the front wheel axel as well.
This prevents them from coming lose like they do love doing.
DO this for a friend, and suddenly it never happens again.
I just used a weaker one so it could still be taken off (with a hammer drill :) )
In fact when I update any parts I use thread lock.
Loctite makes a thread locker for just about every application, why not use it.

Gcn Tech, can you guys make another series of bike builds? May I suggest mtb to gravel bike build please 🙏. For those people wanting to dip their toes on transitioning from mtb to road but acts on low budget. A huge thanks in advance 😂.
@gcntech we need super-precise kilowatthour meters and this is why.. for ebike racing. for ebike racing the racers would need all equal battires and not just that, but tiny little boxes that allow only a set amount to go through before shut off. that way the racers have 'exactly' equal amounts of electron potential. if one racer wants to use rear hub, mid drive, front, 750watt, 250 watt.. the race will decide which is more advantagous with the combined effort of an adept athlete.
this is gonna eventually happen and this is what is needed to make it happen.
Mr. GCN Technician ,, Why Corean legends???? Have you been drinking ???
For God's sake !!!
Should move, but doesn't = use WD-40
Moves but shouldn't = use duct tape
strength index:
1- purple
2- blue
3- red
Clearly no color theorists were consulted.
You brits and your strange words for things. In America, we call that "red" instead of "purple".
In all seriousness, there is red thread lock and it is strong. Putting weaker thread lock in a bottle the color of strong thread lock seems like a pretty questionable idea.
Ever notice how all the big name YT hobby channels are all corporate owned and way more interested in selling you crap then promoting the hobby?
