Columba SP26S and Columba RB28S 16" extended seat post is for taller people whose height is over 6'0" and less than 6'2" This seat post is 25.4mm in diameter, and 16 inch in length. It is designed for SP26S and RB28S bikes. For installation, just take off the existing seat post, replace with this seat post, then put seat post all the way into frame socket until you can not see the minimum insertion mark. Make sure quick release handle is in locked position for bike frame. If you purchase this item with our Columba folding bike as one order, your shipping charge for seat post will be reduced. Enjoy your ride!
