Five common methods for seat tube size selection
1. Look at the original 1 seat tube on the frame, there will usually be a size mark, buy according to this mark, generally you cant go wrong
2. Commonly used data
Measuring length = size (diameter) to be purchased
86mm=27.2mm
97mm=30.8mm
100mm=31.6mm
4. If the size is not marked, or if you buy a new frame, you can use a small piece of paper to circle the seat post and make a mark on the heavy box.
5. Use a ruler to measure the length and divide by the pi ratio π (3.1415926).
For example, if the measured length is 86mm, then the diameter of the tube socket is 27.2mm, because the length is manually measured.
When the calculated value is close to which specification in the table is that specification.
