Pitlock Set 14 – Seatpost Security incl. Seat Clamp
The Pitlock seat clamp keeps your seatpost firmly in place and is the ideal companion to the Pitlock seatpost axle lock. It is made from anodised aluminium, matt sandblasted, and available in several sizes in both silver and black.
Good to know: If your existing seat clamp has flat, even and parallel clamping surfaces, you can generally continue to use it. If not, you will find the right alternative here, perfectly matched to the Pitlock system.
Why Secure Your Seatpost?
Saddles and seatposts are among the most frequently stolen bicycle components. They can be removed in seconds with a standard Allen key. Vandalism is another underestimated risk: if a thief cannot take the saddle, they will sometimes simply damage it instead. Pitlock Set 14 replaces the standard clamp bolt with a coded locking system that can only be opened with your personal PIT key. No special tools, no electronics, just reliable mechanics.
How to Measure
The installation width is the distance between the two outer faces where the axle sits in the seat clamp. This measurement is decisive for choosing the correct PITLOCK axle.
The size of the seat clamp refers to its inner diameter. You can usually find the required size printed on the seat tube or on the old clamp. Measure the outer diameter at the end of the seat tube on the frame. Ideally, the seat tube outer diameter should be slightly smaller than the clamp size.

The PITLOCK Principle
Not only the coded nut protects against theft but also the particularly designed spring washer. It anchors with our coded nut and locks the closure. In order to undo the system the Pit key is used. The Pit keys side panels press and turn the springs of the spring washer at the same time, a principle comparable to child safety locks on certain medicine bottles. Thanks to this principle on the one hand and to the chamfered coded nut on the other hand, pliers will not have a chance to break our system. In addition the conical security ring is pivoted so that it can not be cut by using force.
PITLOCK is made of certified, high-quality and stainless steel and 10 Nm are more than sufficient (not the case for solid axles) to stick the hub incl. the bicycles fork.
Keep Your Bike From Being Stolen
Dos and Don'ts to make it more difficult for thieves to succeed
Dos
- Always mark your bicycle.
- Always lock your bicycle (even in hallways) to a sturdy object (a wooden garden fence, e.g. would not be very suitable...).
- Always choose carefully where you want to park your bicycle, it will determine its fate.
- Always look for a crowded place that is lit brightly to park your bicycle, e.g. in front of the nearest pub. The same applies to railway and bus stations.
- Always use all of the locking devices (PITLOCK security, caps, bars etc.) available.
- Always make sure to let the locking mechanism point downwards and leave as little space as possible between the lock and the bike, so the thief will not have any direct access to it.
- Always make sure to park and lock your bicycle in an upright position without giving the thief a chance to lay it down.
- Always shorten the PITLOCK axle as much as possible, so it will not stick out too much.
Dont's
- Never park your bicycle near locations that tell the thief for how long the bike will be left unattended. One example would be outside of a cinema. Here thieves can be certain to have time until the ending of the movie.
- Try to avoid parking your bike outsides overnight.
- A wheel lock is not secure enough, even if you are only absent for a short time. Consider purchasing the PITLOCK backups that will secure your removable bicycle parts.
- Never put the lock close to the ground, since that position makes it easier for thieves to smash it open with a hammer.
- Never leave any tools with your bicycle! Although these will be helpful when having a flat tire etc., but they will also be helpful for thieves.
- Never leave your PITLOCK key with your bike.
Secure your removable bicycle parts, such as the wheels, the seat, the ahead system and the brakes with PITLOCK, so that the valuable individual parts are also secured against theft.
We would be happy to receive additional hints from you.
Do standard lengths suit my bicycle?
The PITLOCK standard axles replace customary quick releases and are suitable for most bicycles. Racing bikes are special and not a standard. Since race bikes are thinner it results that the axles protrude unfortunately.
Even though we offer a broad range of several axle lengths, we are not able to cover all sizes. At best you measure the axle first, or you contact us for our advice.
The axle thread can only be shortened with the help of a hacksaw.
Attention: Please be very careful when shortening the axle.
In case the axle thread protrudes the security rings for approximately 5 mm it is possible to install our elegant end caps.
How much does PITLOCK weigh?
A saddle axle SA 33 with closure weighs approximately 25 gr.
A front wheel axle VA 119 with closure weighs approximately 41 gr.
TA rear wheel axle HA 155 with closure weighs approximately 47 gr.
A Pit key weighs approximately 11 gr.
A set 02 with packing weighs approximately 176 gr.
