Full carbon frame. Not good for the rough Berlin streets, but it looks too good.I like the „ass“ of the bike and the smooth chainstays.Steel on the other side would survice for years on the cobblestone highways of berlin. And they look great, too. If could coose, i would take the way in the middle- alloy, wich is also in their portfolio. So every rider can get the material wich fits to his style. A DOSNOVENTA frame is not in my house yet, but their new alloyframes are on my „FRAMES I WANT TO RIDE“ list.
