This is a very cleverly produced lock in which three pins in the key fit into downward tapered groves in the lock, and I am very pleased to have this lock on the wheels on my bike. The directions, however, caution the user to be very careful not to over tighten the lock - and for good reason!! While a snug fit works well with the wheel skewers, a much tighter fit is needed with the seat so that it doesn't slide down. I kept tightening and trying the lock on the seat until it no longer fell down when riding. Unfortunately, this degree of tightness prevented it from being loosened for an additional adjustment. I had to grind the lock off to get it loose. So...., a good product, but not when used where a tight fit is needed. A better bet would be the two piece wheel set, also sold by OnGuard (OnGuard Wheel & Seat Locks 2 piece set Front & Rear Wheel QR Locks).

Great way to guard against component theft- which is often overlooked. Without locking skewers, any thief with an allen key can walk off with your seatpost or wheels in a few minutes.

My only complaint is that they do not have the option of a headset lock. If you want to get that, my recommendation would be the "Pitlock" skewers (made in germany, more expensive).

Still, a great value and a major deterrent against theft.

After experiencing thefts of several bicycles and stripping of bicycle parts on secured bicycles in Chicago, Boston and various suburban areas, I decided to upgrade my theft-prevention measures when I moved to the bicycle theft capital of North America - NYC. Locking skewers were top on my list as I previously had a suspension fork stolen from a bicycle with the front wheel and frame secured. In other words, the front wheel quick release was disengaged to steal the fork after the headset was dissembled. Since I employed locking skewers, I have experienced no bicycle or bicycle part thefts, other than an unsecured light.

My first experience with locking skewers came in 2005 when the Kryptonite skewers were still available. They actually seemed a bit more secure than the Onguard variant but neither was ever defeated. After moving and purchasing a new bicycle in 2006, I installed the Onguard Skewers and have been very happy with their operation since. My only problem has been the rare occasion when I would drop off the bicycle at a repair shop and forget to give the repair technician the key. Most of my riding is in the city, so I have not needed to do repairs in the field. This is something to consider as one would need the key to adjust the seat or replace a flat tire.

These skewers have been used extensively in winter conditions where they were exposed to road salt and slush. There is virtually no corrosion after five years. Essentially, they have been absolutely problem free despite the harsh environmental exposure. And, of course, the wheels and seat are still on the bicycle.

Unforeseen benefits arise once the skewers are in place. One is that the front wheel alone can be secured to a rack/fence where bicycle parking space is limited.

Bought this product to protect a very expensive rear hub, and installed both wheel skewers, though not the seat one. Please note: I followed the installation instructions to the letter, paying special attention to the amount of torque because of the specificity of the instructions.

After a total of about 50 miles of city riding, I went up on my hoods to climb a hill and my rear wheel fell off! My left pedal jacked up my calf, and the chain and gears jacked up the paint on my chain stays, but luckily the hub seems undamaged.

Anyway...buyer beware. There seems to be a very fine line between getting enough torque to keep the wheel on the bike and getting so much that it shears the skewer off.

these skewers are a good concept and work great on the front wheel. HOWEVER, if you have horizontal dropouts in your bike (seen in vintage imported road bikes) you probably WILL NOT be ABLE to get the rear skewer to work and your wheel will fall off. not only does this suck, b/c you'll be out your money, but also its a road hazard. OnGuard REALLY NEEDS to put some warning on the packaging about this issue. and yes, I installed them correctly (as did the 3 other mechanics who tried).

These have worked so far to keep my front and back wheels secure, as well as seatpost. I give 4 stars instead of 5 only because I bought three sets of these for three different bikes, and one key opened two sets of the three. A friend of mine purchased another two (on my suggestion) and one of his keys opens my third set.

So, though I feel far more secure than having quick-lock skewers, I don't feel like these are perfect. I still lock the back wheel through my Kryptonite U-lock, because why not? But I think it's at least slightly less necessary than it used to be.

NOTE: some posts can't accommodate the seatpost lock. Look at the shape of the inside. The curves are different on some seatposts.

I can't get enough of these things. After having my seat stolen and dropping $40 on a seat post and a saddle, these little guys are obviously worth every penny.

I combine this kit with a combo U-Lock, set the U-Lock around the frame and throw my bike anywhere, feeling basically invincible.

Preventing bike theft is about increasing the hassle just enough to divert anyone thinking about it.. and these clearly accomplish that.

A little bit of a hassle to carry the key around, and forgetting it is awful, but if you ever lock your bike outside, these are absolutely worth the investment.
