Frequently Asked Questions (FAQs)

1. How do I know what size seat clamp 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.
