Selling a used Centric carbon CX frameset. I got the frame used with the intentions of building a CX bike. Never happened.
I think it is a 57. I took photos of the top tube and seat tube so you can get a sense of the geometry.
As a used frame it comes with a few wear marks. There is tape residue on the chainstay where a cable tie down was attached. There are other cosmetic marks on the frame.

Local pick up in Pasadena is available
