Quick-release seat clamp made from forged aluminium
If you want to adjust saddle height quickly on the go while keeping a clean look, a quick-release seat clamp is a practical solution. This model by JH Design is a lightly forged seat clamp made from 6000-series aluminium alloy. The clamp comes in black and is available in several diameters so you can select the right fit for your frame.
who is this seat clamp for?
This clamp suits riders who want a clean, understated look at the seat tube and want to adjust the seatpost quickly without tools. Thanks to the quick-release lever, you can open and re-clamp without any tools. For finer adjustment, an integrated flat-profile dial allows precise control over clamp tension.

Compatibility and selection guide
To ensure the seat clamp fits, the most important measurement is the clamp diameter at the frame seat tube. The listed diameters refer to the outside diameter at the seat tube. If unsure, measure your frame or check the label on your current clamp.
Pre-purchase checklist
- Measure the required clamp diameter (e.g. 31.8 mm or 34.9 mm) on your frame
- Compare the value with your current seat clamp if available
- Make sure you need a quick-release clamp (QR) and not a bolt clamp
- Consider the desired look: black, discreet on the frame
FAQ about the seat clamp
How do I choose the right diameter?
Choose exactly the diameter your frame requires at the seat tube (e.g. 28.6 mm, 30.0 mm, 31.8 mm or 34.9 mm). If the size is wrong, the clamp will not close correctly or will sit too loosely.
Can I fine-tune the clamping force?
Yes, using the flat-profile dial you can fine-tune the clamp tension before closing the quick-release lever.
