Setup and Installation
- Measure Your Seat Tube: Before installation, accurately measure the outer diameter (O.D.) of your bike's seat tube. Use a caliper for precise measurement. This is crucial for selecting the correct clamp size.
- Select Correct Clamp Size: Based on your measurement, choose a quick release clamp that matches the outer diameter of your seat tube. Common sizes include 28.6mm, 31.8mm, and 34.9mm.
- Position the Clamp: Slide the quick release clamp onto the seat tube, ensuring it sits flush and securely around the tube.
- Insert Seat Post: Insert your bike's seat post into the seat tube through the clamp. Adjust the seat post to your desired height.
- Secure the Clamp: Close the quick release lever firmly. If the lever is too loose or too tight, adjust the tension by rotating the nut on the opposite side of the lever. Turn clockwise to tighten, counter-clockwise to loosen. The lever should require moderate force to close, indicating a secure hold without excessive strain.

Operating Instructions
The Lohas Select KCG521 Quick Release Clamp allows for tool-free adjustment of your bike's seat height.
- To Loosen: Pull the quick release lever outwards to open the clamp. This will allow the seat post to move freely up or down.
- To Adjust Height: Move the seat post to your desired riding height. Ensure the minimum insertion mark on your seat post remains inside the bike frame.
- To Secure: Push the quick release lever inwards until it is fully closed and flush with the clamp body. The lever should feel firm when closing, indicating a secure hold. If it's too easy or too difficult to close, adjust the tension nut as described in the Setup section.
Maintenance
- Cleaning: Periodically clean the clamp and the area of the seat tube it grips. Use a soft cloth and mild soap or a bike-specific cleaner. Avoid abrasive materials that could scratch the finish.
- Lubrication: Apply a small amount of light grease or anti-seize compound to the threads of the quick release skewer and the pivot point of the lever once or twice a year, or as needed. This ensures smooth operation and prevents corrosion.
- Inspection: Regularly inspect the clamp for any signs of wear, damage, or corrosion. Check that the lever operates smoothly and that the clamp holds the seat post securely. Replace the clamp if any damage is observed.
- Tightness Check: Before each ride, quickly check that the quick release lever is securely closed and the seat post does not slip.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Seat post slips down | Clamp not tight enough; incorrect clamp size; dirty seat tube/post. | Tighten the tension nut on the quick release. Ensure the clamp size matches your seat tube O.D. Clean the seat tube and seat post. |
| Lever is too hard to close | Clamp is overtightened; debris in mechanism. | Loosen the tension nut slightly. Clean the quick release mechanism. |
| Lever feels loose when closed | Clamp is too loose. | Tighten the tension nut until moderate force is required to close the lever. |
