KS Ether Seatpost Clamp

A quick-release clamp is ideal if you frequently adjust your saddle height, such as when switching between climbing and descending or sharing a bike with another rider. It allows you to make these changes instantly by hand, without needing to carry or use a hex key.

Seatpost clamp size is determined by the outer diameter of your bike's seat tube, not the diameter of the seatpost itself. You can usually find this measurement etched on your current seatpost clamp or by checking your frame manufacturer's specifications.
