Hi Everyone,
I only did 75 km with the DF Haube and I can say that I am very happy with it so far. Here is why:
The visor is easy to open/close, it is very transparent (low refractive index material), it doesn't scratch easily (in comparison to the Lexan on the Wim Schermer racecap), it doesn't fog inside (and I don't even have the pin lock system), it is very hydrophobic and it doesn't vibrate.
The Haube is stiff, it doesn't flex when there is a big bump (on my XS, the racecap was banging against the side of my head when there was a big dump. Thanks to its stiffness, only 2 hooks are necessary to attach it, so it's very fast and convenient to put it / take it out.
The ventilation of the Haube: when you open the visor of only 1 step, it is very good. When it is closed, the air coming from the tube of the DF isn't enough for my likings. The hole behind the head are very well though about: there is no wind entering there, even by side wind. It makes the ride quiet but still ventilated.
The side windows can have a little bit of fog if the visor stays closed.
The speed gain is also clearly noticeable. I will collect more data to give a reliable value, but so far, my impression is that I gain 3km/h at 150 watts, which is a lot!
Conclusion: I am very happy with the Haube, I really don’t see anything negative about it. Congratulations for the design and innovations to Daniel. A big thanks to velomobiel.ro for making such a high quality of production.
