How to measure and confirm the diameter that you need: - Please do measure and confirm the exact post diameter that you need for your bike. Otherwise, you may find it too small or too large for your bike frame seatpost hole, and then you'll have to spend more time to return it.

There are two ways to confirm the diameter that you exactly need: 1. Check the diameter mark on your old seatpost, normally there's a size mark on your old seatpost. For example, if there's a mark "Φ25.4" on your old seatpost, then you can buy a new 25.4mm seatpost. 2. If you have a vernier caliper, measure your old seatpost diameter, or measure the inner diameter of the seatpost hole, then buy a similar size new seatpost. For example, if the measurement is about 27.1mm, then select a 27.2mm seatpost. 3. If you don't have a vernier caliper, use a small stick to measure the inner diameter of the seatpost hole (see the picture showing).

To fit frame seatpost hole: 25.4mm Important note: the real measure of the seatpost diameter is a little smaller than the number marks on it. e.g., a 25.4mm one may measure about 25.0~25.2mm only.
