This Corratec model is from 2005. The lighter one is from 2000, but the frame is the same, so i´ve changed the decals for these, ´cause i think they are better looking. I was the official distribuitor (dealer, retailer, don´t know how to say) back in 96 ´till 2000, and i still have a good relation with the factory in Germany.
Corratec still sells this Titanium frame, altough it´s not in the catalogue or in the web page. Just have to ask.
Size M weight´s 1540g, has a very racing geometry, and the ideia of the 2 top tubes (besides the unique look) is to better "spread" the rear wheel vibrations into the frame, so it´s a bit more confortable. On the track, it´s more or less like that.
