I wish they were silver, not black, but they look worthwhile.
Anyone have any experience with them?

I don't have those, but I have another set of security hubs. Makes locking-up a lot less of a hassle. (my wife and I can share a u-lock now when we go out on bikes together).

I like the idea. I'd still lock the wheels mind you, but it's a nice compromise between regular (please mess with me) QR's and Pitlocks (hope like hell you have the bits when you flat).

Might order a few sets.

I also like the idea too, although I should see about buying a set or two to play around with, and see if there are any glaring weaknesses that a casual thief could exploit. Assuming it has none, it definitely will prevent people popping seatpost QRs and chucking seats ontop of roofs or power lines (which is common around UT here.) It definitely offers great passive security where you don't have to worry about keeping a keyed nut or a key with you that can get lost or left at home.

On a good bike with decent wheels or front suspension, I still would stick with a set of Pitlocks that protect the fork because its not unheard of for someone to lose a very good chunk of their bike that way, even when they lock the wheels and the frame securely.

I have a different kind (Pinhead). Those look interesting though.

Note: The pinhead locking seat clamp parts were completely incompatible with my surly seat clamp. After fastening a bolt which was actually long enough I couldn't get the clamp tight enough to hold the seat up.

The wheel skewers seem to work great though.

Interesting. My concern though is a thief may think they're normal QR's and mess up your wheel trying to remove them. Price is right though and I like the fact you don't need to carry a key.
