Wheels Manufacturing Seatpost Clamp

The 34.9mm measurement refers to the outer diameter of your seat tube, not the seatpost itself. You can verify your frame's requirement by checking the specs on your bike manufacturer's website or by using a digital caliper to measure the outside of the seat tube where the clamp sits.

A bolt and barrel nut system is generally more secure and less prone to slipping than a quick-release lever. It is ideal for riders who have found their ideal saddle height and do not need to adjust it frequently, as it provides a consistent, reliable clamping force.

6061 aluminum is a standard in cycling components because it offers an excellent strength-to-weight ratio. It is durable enough to handle the torque required to keep your seatpost locked in place while remaining lightweight.

Maintenance is minimal. It is a good practice to occasionally clean the bolt threads and apply a light layer of grease to ensure the bolt turns smoothly and clamps evenly without seizing.

Yes, this clamp is compatible with both carbon and alloy seatposts. However, if you are using a carbon post, be careful not to overtighten the bolt; using a torque wrench to meet your frame or post manufacturer's specifications is recommended to prevent damage.
