Extralite Releases Ultrapost 31.6 – Lightweight 3D Machined 99g Seatpost
Extralite has just released their new Ultrapost, a 3D CNC machined alloy post that comes in as light as 99g for the 31.6 x 250mm. There’s also a 300mm length at 138g, both of which rival (or best in many cases) carbon fiber posts in weight.
The clamping mechanism is heavily machined to reduce material while still providing decent clamping area…just not much of a platform for the bottom of the saddle rails. The dual bolt design makes tilt adjustments super easy, a design shared by posts from Thomson and others and our preference.
The post surface is ceramic bead blasted then anodized black with laser etched graphics. Inside, the tube is “multishaped” through CNCing to reduce weight where they can. Clamp and post are 7075 alloy, bolts are titanium. More pics after the break…
Clamping surfaces are smoothed to reduce shearing stresses and makes them approved for use with carbon rails. No word on rider weight limit yet.
