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 seat post hole, then you'll have to spend more time to return it. Thank you for your support.

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