If no marking is available, use a caliper to measure the outside diameter of the seatpost.
Measure the frame seat tube inner diameter
If you do not have the old seatpost, measure the inner diameter of the bike frame seat tube.
Choose the closest matching size
Select the seatpost size that matches your frame diameter. Please confirm carefully before ordering.
