Bicycle Seat Post, Aluminum Alloy Seatpost Length 450mm 28.6mm Bike Replacement Seatpost for Mountain & Road Bikes, Matte Black

Description:
Please do measure and confirm the exact post diameter that you need for your bike.
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 " 25.4"on your old seat post, then you can buy a new 25.4mm seat post.
2. If you have a vernier calliper, measure your old seat post diameter or measure the inner diameter of the seat post 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).
