There is a bezel/notch on the inside of the seat post clamp. When clamped this prevents slippage.

The frame tube's outer diameter needs to be measured. then check the size range with our 31.8mm and 34.9mm to see which is compatible.

Adjustable Quick Release Seatpost Clamp

When you’re sitting with full weight on your seat post and saddle you don’t want the post constantly slipping. A high-quality quick adjust seatpost clamp ensures your seat post is secure and centrally aligned. 

To ensure the Corki Cycles seat post clamp stays positioned at the top of your frame we use a small internal notch inside the clamp. This prevents the need for over-tightening, damaging your bike frame, and ensuring a quality bicycle component.

If your bike is used for various riding styles, you want the ability to quickly lower or heighten your seat post without an Allen key. A quick release clamp is the perfect hassle-free bike component for this. Unclip the quick release clamp, adjust the seat post height, centrally align the saddle, and lock the quick release into position. With the quick release bolt, you can tighten safely up to 5Nm. Never over-tighten as this can damage your bike frame. More so before buying always measure your bicycle frame seatpost inner and outer diameter.

Corki Cycles provides three sizes of adjustable quick-release seatpost clamps -28.6mm, 31.8mm, and 34.9mm. Choose between 2 colors black and red. 

Adjustable Quick Release Seatpost Clamp Diameter

When fitting a new quick release seat post clamp it is important to order the correct size diameter. Failure to do so can mean a poorly fitting and performing seat post clamp.

The Corki Cycles quick-release seat post clamp comes in 3 sizes. The 28.6mm diameter seatpost suits 27.8 mm-28.8 mm diameters. The 31.8mm diameter seat post clamp is suitable for 30.2mm - 32.1mm diameter bicycle seat tubes. The 34.9mm seat post clamp is suitable for 33.5mm - 35.2mm bicycle seat tubes. To fit add a little grease to the seat post clamp as well as your seat post and tighten securely.

The Corki Cycles quick release bicycle seat post clamp is made from Aluminum 6061.  They're ultralight, strong, and durable. Each seat post clamp is made with a CNC machine ensuring precision and quality. Every seat post clamp comes with a durable quick-release clamp to securely fasten the seat post. To adjust the quick-release clamp's tightness, adjust the connecting bolt by loosening and reclamping.

At Corki Cycles we believe in buying bicycle components that are strong and built for all styles of riding. Nevertheless, as you push the limits of your riding, components inevitably break or are affected by general wear and tear. With every adjustable quick-release seatpost clamp, you receive a 2-year limited warranty. We also offer a component replacement scheme where we provide a discount on your new bicycle component. Send our friendly customer service a message for further information.

Quick release appears to be well-made, and I suspect it will last a long time

The Corki Quick Release was easy to install on my child's WOOM OFF 4 bike and works great! After installing, our five year old can easily adjust the height of this seat post whenever needed. When we mountain bike together, he raises his seat for the climbs and drops it for the descents. Quick release appears to be well-made, and I suspect it will last a long time.

Great seat post

Great seat post. The called out size is perfect. Nice anodize, looks great. Nice long lever to compress without damaging the carbon fiber frame and post. I am 100% happy with my purchase.

This did the trick and was perfect!

My bike had a baby seat attached when I bought it, so I needed a clamp when we removed the baby carrier. This did the trick and was perfect! I initially bought the smaller size and needed to return for the larger.
