The Ridley X-Knight, below, was one of the very first carbon cyclo-cross bikes but it's now joined in the mud by Colnago's C50 Cross. Already being tested by Rabobank 'cross stars Sven Nijs and Richard Gronendaal, the C50 Cross is the newest member of the C50 family of five (Road-Track-Crono-MTB-Cross). After a season of race testing to refine this off-road dream bike, look for Colnago's C50 Cross at a cyclocross store near you.
Actually ALAN made the very first carbon cross bike! ALAN has been producing frames in Italy since 1972. ALAN is now making a cross frame called the X40. If you look closely it looks allot like the Colnago and the new Guerciotti seen at Eurobike. That is because ALAN dose contract work for other companies. I just built up a new ALAN X40 and I can tell you it rides better than my road bike.
