I wish Chunky was an angry Pitbull that had the chance to tear his previous owners to shreds.

People are cnuts and I hope the axe of karma drops on their heads.

I saw a short film somewhere (phone wanted to change that to shit, which is not inaccurate) about some crimson trapped in a warehouse with a torn up old fighting pitbull trying to kill them...

Probably the same people that blow thousands on the pokies or on holidays to Bali.

Loctite on a bike.... do/don’t, where, colour?
I understand the stuff about as well as the 40 different grease varieties you can get....

Most people seem to. I don't unless I have something that won't hold tight, which is not.very often. I'm no good with colours but have a red and black. I remember learning on here that once you have cleaned the mating surfaces you need to wd-40 the "both" and the nut gets loctite and a thin smear of grease once the loctite has dried. The urgency of moderation with all ingredients can not be stressed enough!

WD40, loctite, and grease all on the same surfaces is pretty counter-intuitive...

The bike industry has a weird affinity for loctite, but I guess a lot of it is just for extra safety to cover their asses so bits don't rattle loose on those who never ever perform any maintenance on their bikes. Blue loctite (medium strength) is generally stock for most bolts, however some lower end tektro stuff comes with red (maximum strength). The only bolts that (normally) come loctited from stock are the brake mounting bolts and the disc bolts, and sometimes linkage bolts (white low-strength) depending on the brand.

IMO generally loctite is overkill as long you correctly torque everything. On a bike, I would only ever loctite things which are coming loose that shouldn't be. Grease and torque everything else.

Blue loctite 243. On bolts you don't want to vibrate loose like brake bolts, disc rotor bolts and sometimes suspension pivot bolts.

Other greases you need are:
-Anti-seize. Most other bolts and also headset and bb cup installation.
-Blue marine grease. Most other metal to metal contact.
-Carbon assembly paste. Handle bars, seat post clamps etc.

You can get more specialised greases for bearing, hub and suspension service.

Having a bolt that both will and won't come undone until someone tries to touch it? Schrodinger's bolt?
Exactly. Somewhere there is a balance between all these different substances...the point of perfection. The most critical aspects of good surface mating are ensuring there is no particulate obstructions and achieving a smooth penetration. The wd-40 eliminates the risk of particulate obstruction, the grease aids penetration, and then (and only then) will the loctite be able to do its work and ensure the mated surfaces are locked tight.

Also note that if you are using the loctite on areas subject to friction heat exchange (such as linkages and sound the brakes) you should he using one rated to a reasonable heat level.

Slides in without friction, holds tightly once in, and wont seize. It's pretty much the golden standard around here.
So if you coat the loctite in grease, how does that extra layer between the loctite and the bolt help it increase friction with the female thread it gets threaded into? You've just lubricated the outside of the bolt , effectively nullifying the idea of the loctite as you've prevented it from forming a secure seal with the female thread. Loctite cures in the absence of air, hence you can put it on and thread it in while still wet, that should be more than enough temporary lubrication unless your threads are damaged.

Seizing primarily occurs from corrosion. If applied corrected, loctite will replace the job of grease and prevent any corrosion. While the bolt will now have more friction to remove, therefore requiring more force (a.k.a, loctite doing its job), the bolts shouldn't seize.

You don't ever put grease on brake or rotor bolts that are loctited, so why should you do it to any other bolts that are loctited?
