Bingham Built Sweetpost – Straight – for Carbon Saddle Rails Only


This is your Sweetpost if you use a saddle that has 7×9 oval carbon rails. It’s has the exact same functionality as the Bingham Built Sweetpost, but the hardware is different and will accommodate a saddle with 7×9 carbon rails. You can purchase the hardware kit alone if you already own a Bingham Built Sweetpost here. See specs and torque specs below.

An evolution of the renowned Kent Eriksen Sweetpost, we’re proud of this simple, strong, functional, and clean design. The main objective for creating a new design was to increase durability, ease of use, and of course beautiful aesthetics. A Key feature is two outer bolts and one inner bolt to allow for easy independent rotational and fore/aft saddle adjustments to find your perfect saddle position without any hassle. Designed in house and made with 3/2.5 titanium sourced from Alleima metals (Previously Sandvik metals), a leading domestic supplier of the highest quality certified titanium available. The inner hardware is Aluminium machined by Paragon Machines Works. The outer caps are 3D printed, titanium, by Silca.

There are some carbon rail saddles out there that do NOT have standard 7x9mm oval rails and this will NOT be compatible with those. You can check your saddle manufacturers website for the specs/details. Just make sure the specs say 7x9mm rails. Anything else like 7.1x9mm or 7x10mm will not work. Also, anything that has metal reinforcements on the rail like some versions of the Selle SMP FC will not work. Bottom line is that is has to have standard carbon rails in a 7x9mm oval shape with nothing wrapped around the rail (like some older Fizik saddles have). Email us if you have questions or if you're not sure about this.
