What size seatpost clamp do I need?

Note: The seat clamp diameter needs to match the diameter of your seat tube rather than your seatpost, which is a little smaller. For example, a 27.2mm seatpost (a size commonly found on road bikes) fits inside a 28.6mm diameter seat tube, so it’s a 28.6mm clamp you need.

How do you measure seatpost clamp diameter?

The best way to make sure you’re getting the right size is to grab a set of calipers. Just ask your closest engineer- she’s bound to have a set. Stick the calipers on the outside of the seat tube, and measure away! You can also measure the inside of the seat clamp that is currently on your bike.
