What size seat clamp do I need?

Understanding the relationship between your seatpost and the seat tube clamp is essential for a secure fit. Here is a quick guide based on common industry standards.

Example: For a 30.9mm seatpost, you will predominantly need a 34.9mm seat tube clamp. The extra diameter accounts for the thickness of the frame's seat tube.
