Temperatures changes and bolts

Clamp head saddle rail bolts can get loose, and might undo enough for the saddle to slip back, I think it's due to temperatures changes & the loads, this is what happens when you take the bike out from the warm home out and ride for few minutes in subzero temps, When I got home I had to fix this.and yes I had on Loctite 243, but this eventually happens anyway, Loctite eventually needs reapplying.

So a multi tool is a must, even if everything on the bike has been checked.

But I haven't had issues like this on the Renthal Apex stem, but with Atlas Stem I had to Check it before and after every ride, and during ride to be sure bolt's did not get loose and the handle bar were spinning.

also I got issue with Hope Tech Seat post clamp & Shimano brake levers too. the bolts might undo enough for the saddle to slip back, but these are side effects rapid temperature change, shrinking things slightly, of course different materials will be effected at different rates. You just have to expect this and tighten it down when you are out and check suspension too see if pressures are right, because it can drop a lot, so if this post was a air post it would need to to work with something like 10psi drop or increase, but as this is a mechanic dropper post you don't have to worry about the pressure.
