Principia Prototype?!

New frame from Principia, spotted in Danmark at Århus Festuges Gadeløb Race. Meanwhile there are some unconfirmed information available. The source says that the frame uses a newly developed hollow carbon fibre, successor of the C60T fiber used in their limited edition. The seattube is carried out in a one piece design ( bottom bracket to seatpost ), which is supposed to increase stiffness according to the manufacturer. The weight for a 57cm sized frame is about 740g, with a STW value which beats the current market benchmarks. Pretended market launch in March 2008.
