I fit the size xl and there are a very good offer on the H30 at the moment. The dealers show only pictures of the smaller frame M, L and the size xl looks a bit different. I can see that in the area around the reardamper.
There are only one picture to find on the web of an orbea oiz 2020 size xl aluminium. Nothing on youtube of the alu size xl. Orbeas webside only shows picture of a M or L frame. Unfortunatly the size xl is not to find in any Orbea-shop in my area only in size L.

Do you have one in xl? Could you post a picture from the side so i could see it?
