I put my Free Rad on a aluminum frame. I am assuming that CF =carbon fiber.
I don't believe that you would have any problem getting it to fit, how it would hold up would be a whole other game.
I have no experience with carbon fiber parts at all,nor do I have any desire to. I have heard that they can be susceptible to sudden failure.
I also have issues with automatic transmissions in trucks
I am sure they are fine,just can't seem to wrap my mind around the concept. Same thing with carbon fiber frames.
I wish that I could be of more help to you. If you are thinking of getting a Free Radical I would say go for it, even if you need to get another donor frame.
I have had mine for a little over a year now, since I got it my other two bikes haven't seen the road
As a matter of fact I am considering getting rid of them.
I can see a Big Dummy in my future,maybe not soon but definitely.
I set mine up on an old specialized hard rock frame. I like having a cro-mo frame with the cro-mo xtracycle kit. I'm sure that you could, but from what I know of carbon fiber, is that it can handle certain forces very well, but others very very poorly; and I wouldn't doubt that the xtracycle could change the geometry enough to put some real torque on it that the designer never thought would be put on it.
