Can I shorten a bike seatpost?
Condensed answer: A bicycle seat post can be cut as long as the new size respects the minimum insertion length of the seat post. Ignoring the minimum insertion length and cutting too much of the seat post will result in extra stress on the frame (seat tube) and may cause a crack.

How much does it cost to cut off a seatpost?
Actually it’s more like the minimum insertion mark on the seatpost is 30% of the way up the post, cut three inches off and it will still be 30% of the way up the post, so less than 3″.

How do you measure a diameter?
If you know the radius of the circle, double it to get the diameter. The radius is the distance from the center of the circle to its edge. If the radius of the circle is 4 cm, then the diameter of the circle is 4 cm x 2, or 8 cm. If you know the circumference of the circle, divide it by π to get the diameter.
How do you measure seatpost clamp diameter?
The best way to make sure you’re getting the right size is to grab a set of calipers. Just ask your closest engineer- she’s bound to have a set. Stick the calipers on the outside of the seat tube, and measure away! You can also measure the inside of the seat clamp that is currently on your bike.
