Three ways to choose the right seatpost size:
1. Pull out the old seatpost and check whether there is a specification mark at the warning line under the seatpost. For example, if it shows 27.2, the number 27.2 is the diameter.
2. Make a circle around the seatpost with thin paper, and then draw mark on the paper, and divide the data measured with a ruler by 3.14 to get the diameter of the circle.
3. Directly measure the diameter of the seatpost.
