Would you happen to know the required seat tube clamp size for a Tetra-Pro? It isn't 31.8mm because I tried that and it doesn't work.
With the carbon sleeve in place, use a 35mm (1 3/8") clamp.
Sorry, I guess I didn't make the question clear enough. I am referring to the seat tube clamp for the seat post. I actually received a very quick response from Craig Calfee that it is 33mm - custom for Calfee frames.
