Me and my mate were doin some trials riding in town today and after an hour or 2 I went to try doing this skinnie, risking a swim in the sea if anything went wrong but just before I got going I noticed that I was missing the bolt that holds my left crank on! Not the pinch nut but the big meaty one in the middle.
We retraced where we’d been to no avail so I went back to the car and swapped my KH for my poxy 20" for the rest of the day (and nailed the skinnie without needing to swim).
On the way back to the car my mate spotted the bolt which was a bit of a small miricle, it was really strange that this happened though because I’d tightened everything before the ride and the bolt had dropped out very early on in the ride. How can I stop this happening again? I’ve heard loctite mentioned but isn’t that only for when you don’t ever want to undo it again?
I think I once heard Blue Loctite to tighten it and stop it from vibrating loose, Red Loctite so it will never come off again for the life of the unicycle, Green Loctite so it will never come off again in your life! I might have the green and the red in the wrong position, but I think it’s right.
So you’re most likely gonna want to use Blue Loctite, just so it won’t come loose from vibration, you’ll still be able to get it undone.
When he replaced it, it would rapidly become loose again. He put loctite (red) on it, let it set overnite, and it has now stayed put ever since.
The red loctite is called “permanent”, but it is not permanent, it can be taken off with a wrench with only little more difficultly than a just freshly tighted bolt.
