How to measure and confirm the diameter that you need

Bike Seatpost 31.6

Observation

Remove the original seat post and check if there is a size mark near the safety line.

As shown in the picture, if it reads 28.6*350, then you need to order a seat post with a diameter of 28.6 mm.

Saddle Pole

Calculation

Wrap a strip of paper around the seat post and make a mark where the paper overlaps.

Then, measure the length of the paper. Divide this measurement by 3.14 to calculate the diameter.

Bike Seatpost Seat Tube

Measurement

If you have a caliper, you can directly measure the outer diameter of the original seat post.

Or the inner diameter of the seat tube.

Please make sure to measure and confirm the exact seat post diameter you need for your bike. If the size is incorrect, it may not fit your bike frame's seat tube properly, causing inconvenience.

Tips: This item is sale as a single bike seat post, the saddle clamp is not included, you can buy a clamp separately or remove one from your old saddle.

The paint finish is of good quality. Made of strong material. The only downside is it doesn't fit my son's bike. It's probably more suitable for standard sized bikes.

This is a super sturdy seat post for either your city or mountain bike adventures. This doesn't come with the clamp, so it works great as a seat extender. Highly recommend for the quality, accessibility, and price. ⭐⭐⭐⭐⭐

This seat post is meticulously crafted from robust steel, boasting a substantial thickness of 2.15 millimeters. The meticulously applied powder coating ensures exceptional protection against corrosion, guaranteeing longevity and reliability. Its seamless integration with my bicycle further enhances its functionality. The aesthetically pleasing design complements the overall appearance of the bicycle, making it a worthwhile investment.

This fit in place of the seat pole that broke. This sat in perfectly and seat attached back, no problem.This lever was very light in weight so it won't add a lot of weight to the total of the bike. I do lift it when not in use on a rack in my garage.
