KCNC SC11 Seatpost Collar

You need to match the clamp size to the outer diameter of your seat tube, not the diameter of your seatpost itself. The easiest way to confirm is to check the markings on your current seatpost clamp or measure your seat tube with a digital caliper.

Yes, the M7 scandium bolt is specifically engineered for the rigors of off-road riding. Its full-length 4mm hex key slot is designed to distribute clamping force evenly, which helps prevent the bolt from snapping under the stress of rough terrain.

Yes, using a torque wrench is highly recommended. The SC11 has a specific tightening range of 8-10 Nm, and staying within this limit ensures the clamp holds securely without damaging the bolt or your frame.

The SC11 prioritizes weight savings through aggressive CNC machining and a unique scalloped band design. It offers a more refined, lightweight alternative to standard clamps while maintaining the structural integrity required for off-road abuse.

While the clamp is compatible with many frames, you should always verify the manufacturer's torque specifications for your specific frame. Because this clamp uses a high-strength bolt, ensure you do not exceed the frame manufacturer's recommended torque limits for the seat tube area.
