Looks like an interesting way to lock your quick release wheels and quick release seatposts

Thats interesting......
although I wonder what complexity they had to add to a relativly simple thing to make it work. great idea though!

Very Clever. I wonder do they rattle?

I'm baffled - can anyone figure out how this works?

Has anyone seen one of them yet? Must be some seriously lateral thinking figuring how they work

Seems reasonably straightforward. There must be some sort of pin/hinge holding the QR in place, internally. Flip the bike up, gravity pulls the pin out of the way and the QR lever can be pulled..

but following that logic, as soon as you turn it 90 or maybe 180 degrees gravity will kick in again and you will need to turn the bike again in order to let you get another half turn on the skewer....

Not necessarily. The locking pin may only prevent you from pulling the lever out, not turning the lever in a circle.

Old thread, but purchased a set of these today.

Anyone had any problems with them?

Thought they would be handy for nipping into shops etc for brief periods where I wouldn't have to remove the front wheel or saddle while locking the frame. I'm sure a pair of vice grips would open them easily enough.

Well it says on the site 'A special washer makes the unscrewing impossible even with a tool'.

Not to rain on the parade of the purchaser but road.cc were somewhat less than impressed by these.
