Bike aero position

Here's my first attempt at an aero position on my new bike. So far I've done nothing more than just move the seat post height half a centimeter. There are all sorts of adjustments I can try form moving the handlebars down to the seat further forward. It is a big improvement on my best position on my road bike.

Second attempt after moving seat back a little

For reference, Timo Bracht in the 2010 IM in Hawaii

I had thought I might not need to sit so far forward on the seat, now that there was no real restriction in how far forward I could move it but it is simply uncomfortable to put my weight any further back on it while I am leaning forward. An alternative would by the Adamo seat which is a bit like a sawn off shotgun and is predicated on the idea that you sit on the edge - or, in this case, the two edges.

The other thing I notice is that my back tends to curve. This is partly to do with my lack of flexibility but it perhaps could do with straightening out a bit by extending the distance between the points of contact of my elbow and my bum. Still, the main thing is that it feels relatively comfortable (we'll see after several hours if I am still saying that) and I believe it is pretty aero in that i am presenting a compact surface area to the oncoming wind.
