What force does a quick release skewer create?
Re: What force does a quick release skewer create?
I tighten mine so I can undo them. I can tighten them more but then need tools to undo them.

I hear ya. I remember as a kid closing them with my foot to make sure they are tight enough.

It also helps if you orientate the lever so the end of it is in open space rather than along a frame tube or fork leg (without going into Velominati rules about QR orientation in this discussion ). Then you can get your fingers behind the lever to release it, even if you have been a bit too enthusiastic with the tightening!

"velominati rules" - hahahahahahaha

Similar skewers that have an allen bolt (but look like QR skewers) say to tighten them to 7 Nm.
Doesn't sound like much to hold a wheel in place, but I assume it grips on the same way a QR does.

The above clamp (or not) in the same way wheel nuts do - the QR skewer multiplies the force (of the palm) via the cam - I suspect the QR clamping force is significantly more than the 7Nm used on the devices above, which is, of course not the clamping force figure, because that is changed via the thread pitch .

It can't be multiplied by more than 4 though just because the thread is fine.fastpedaller wrote: ↑20 Oct 2021, 5:08pmThe above clamp (or not) in the same way wheel nuts do - the QR skewer multiplies the force (of the palm) via the cam - I suspect the QR clamping force is significantly more than the 7Nm used on the devices above, which is, of course not the clamping force figure, because that is changed via the thread pitch .
(7Nm x 4 = 28Nm and that's still just under what Park Tool say for solid axles)
