Many older U.S. made bikes take this thin size. Unfortunately, there's very little choice in this diameter. This Wald galvanized steel seatpost is plenty long, but if fully extended, a heavier rider may well cause it to bend.
Diameter: 13/16" (21.15mm)
Diameter at top is 7/8" (22.2mm) to fit standard seat clamp.
