Description

Q: How can I determine if I have received the correct seat tube size?

A: The size is engraved on the bottom of the seat tube, you need to look at it in sufficient light.

Q: How do I know what seat tube size I need to buy?

A: Please see under the picture, we have four ways to measure the seat tube

Q: The display title indicates that the size is 25.4/27.2/28.6/30.9/31.6mm * 350/400mm, but the display text (which changes depending on the picture clicked) shows different sizes - what is right?

A: Tips: Please choose the correct size according to the display text (which changes depending on the picture clicked). The title contains all the sizes we sell, which is not accurate enough. Please refer to the first description for the correct size.

The first method

Use a digital caliper to measure the width of your seat tube. This method is the most accurate

The second method

Please note the size of the bottom of the old seat post.

The third method

If there is no size engraved on the bottom of your old seat post, you can measure the size of the old seat post with a digital calliper.

The fourth method

Use a toothpick to measure the width of the seat tube, then measure the length of the toothpick. This method is prone to errors, especially the saddle tubes of 27.2 mm and 28.6 mm have small errors and are usually prone to errors.

Various sizes from 27.2 mm, 30.9 mm, 31.6 mm

Q: What do I need to pay special attention?

A: The size difference between 30.9mm and 31.6mm is close, but if it differs from your bike size, the wrong seat post you buy can still not be used normally. Please measure your seat tube before purchasing
