Voxom SAK2 Quick-Release Seatpost Clamp
The Voxom SAK2 is an aluminium bicycle seatpost clamp with a quick-release mechanism. It allows the rider to raise or lower the saddle within seconds without using tools.
Its smooth and compact shape is designed to minimise contact with the rider's legs. A strong retaining bolt and stainless-steel hardware provide secure and dependable clamping.
Fast Saddle-Height Adjustment
The quick-release lever allows the saddle height to be adjusted without an Allen key. This is useful when a bicycle is shared between riders or when the saddle position needs to be changed frequently.
Smooth Low-Profile Design
The clamp has a smooth exterior shape intended to reduce the possibility of catching clothing or making contact with the rider's leg while pedalling.
Aluminium Construction
The aluminium clamp provides a useful balance of low weight, strength and corrosion resistance. A stainless-steel screw is used for dependable everyday operation.
Two Clamp Sizes
The Voxom SAK2 is available in 31.8mm and 34.9mm clamp diameters. The correct size must match the outside diameter of the bicycle frame's seat tube at the clamp position.

Frequently Asked Questions
What does a quick-release seatpost clamp do?
It allows the rider to adjust the saddle height by opening and closing a lever without using tools.
Which size seatpost clamp do I need?
The clamp size must match the outside diameter of the bicycle frame's seat tube at the clamp position. Measure the existing clamp or check the bicycle manufacturer's specification.
Is the clamp size the same as the seatpost diameter?
Not necessarily. Seatpost-clamp size refers to the outside diameter of the frame's seat tube, not the diameter printed on the seatpost itself.
What sizes are available?
The Voxom SAK2 is available in 31.8mm and 34.9mm clamp diameters.
Is the clamp made from aluminium?
Yes. The main clamp is aluminium and uses a stainless-steel screw.
Do I need tools to adjust the saddle height?
No tools are normally required for routine height adjustment. The quick-release tension may require initial setting to provide secure clamping.
Can I use this clamp on a carbon seatpost?
Compatibility depends on the bicycle frame, seatpost and permitted clamping force. Follow the frame and seatpost manufacturers' instructions, particularly when using carbon components.
Select the correct clamp diameter before ordering. Ensure the seatpost cannot twist or slide after closing the lever and before riding.
