Quick and possibly stupid question - given that Maxles have a clockwise thread, how come the stealth versions don’t unscrew while riding along due to precession?
Precession requires a cyclical load. It's not just the opposite of bearing drag.
I'm now trying to figure out in my head if you get bearing drag and precession working together if you only pull on the crank rather than push?
Wouldn’t bearing drag serve to tighten it anyway given it’s threaded in clockwise from the right side?
Cyclical load thing makes sense.
I've had a Maxle come loose.
Possibly vibration/incorrect torque.
It took out the mech and chain.
I do it up FT now.
Stealth.
Maybe I need to have a rethink then. Existing Maxle looking a bit chewed round the collar.
They can. They need properly torquing and checking regularly. UDH have a finer pitch which helps prevent loosening but neither are problematic if looked after.
UDH?

Am I the only one to never have an issue with maxles or give them a second thought, just lubed and correctly torqued, job done, remained totally unchewed and nothing but the faintest of marking from one of the endcaps.
I thought the collar corners getting a bit chewed up was quite common?
Good timing! I was wondering about replacing a 12mm QR through axle with a neater looking allen key equivalent, assuming from above that they just need checking more often?
I think I have a maxle stealth in my revs, never paid much attention to grease or torque, never had any issues, no idea what this chewed collar talk is about. Very possible that I just don't ride my bike enough to know.
Never had any issues with my maxles or fox equivalent.
I do prefer the function of the DT Swiss bolt through ones on my cross bike.
@uniqueusername Maxle Lites had a fixed collar with a notch in it, that the lever sat in while open. You wound the axle in and out by the lever pressing on the notch sides, then when it was about right, closed the lever that was then free to rotate. Unfortunately unless you're really careful it's anecdotally quite easy to bend the notch sides meaning it doesn't really work.
Doesn't apply to Maxle Ultimates (which have a different cam mechanism) or Stealths (which are essentially a big bolt).
The thin collar is/was a crap design. On some forks and frames it was impossible to engage the lever fully while rotating it as it would clash. That inevitably led to the collars getting chewed up. Every other design seems to work better - Brand X, Shimano, DT Swiss, Fox and Stealth.
@ratherbeintobago aha, ok all makes sense now. Mrs unique has something similar on the back of her canyon. Engagement seems solid, but I now know to keep an eye on it.
Fox 15QR’s are a terrible design. A 15mm axle held together with a bit of 9mm threaded rod.
Personally I don’t see the point of a QR lever, I keep a 6mm Allen key in the boot of my car, and another one in my bum bag.

I'm surprised someone's not integrated it into something. Even if they just put an detent or o-ring on an Allen key so itcould be pushed into one end of the other and it stay there.

Doesn't that mean it'll be less stiff than DT Swiss RWS 9mm skewers?

my friend’s Whyte gravel bike had an Allen key poked inside the axle lengthways. So you pull it out and turn it round to use it.

That’s what Formula do.

Less stiff in which way? It’s still a 15mm axle and most the forces acting on it are not in the direction which would be heavily compromised, but its still daft if you ask me.
*It may not be exactly 9mm, I’ve not measured it, but it looks about that.
Is it not made of several bits, one of which isn’t bigger than a traditional threaded axle?
