Five ways to choose seat tube size:
(1) Look at the stencil number at the warning line of the old seat tube (such as 30.4 or 31.6 is the diameter), basically all seat tubes have a clear diameter mark
(2) Use a piece of paper to circle the car tube to get the size, use the calculator to input the size and divide it by 3.14 to get the diameter, and select the closest size.
(3) Measure the diameter of the seat tube directly with a caliper
(4) When there is no seat tube, directly measure the inner diameter of the frame tube
(5) When there is nothing, consult the business that sells the car to you!
