BMX in Oslo or a lighter seatpost?

Starting with a BMX video, Oslo Calling:

And then I have mounted my Engage seatpost, or first I cut 9cm of it 🙂

From the 283g original to this 129g, pretty good weightsaving 🙂

Now just to get a good Body Geometry fit on it and maybe try it for real outside before the spring 🙂 6,34kg will be awesome. Maybe am changing for a little heavier wheelset and a pair of Vittoria Corsa SC 25mm tires, we’ll see when the spring comes.
