From Cheap Carbon Frames
A diagram of a TT frame geometry was sent in by the reader. Maybe we can use this for reference.

From Cheap Carbon Frames - 3K or 12K weave?

From Cheap Carbon Frames
Increase your knowledge about carbon frames. It is time you own a carbon frame (everybody seems to have one because now they are cheaper)
What is the difference between 3K and 12k? It refers to number of fibers/filament: 3k is 3,000 filament per thread; 12 K is 12,000 filaments/thread. Earlier carbon fiber was 3k. Now carbon fiber could be made cheaper with 12 k. However, it has a disadvantage of not being wound tightly.
Unfortunately we can not see of which carbon type a bike has been constructed because they are built with layers upon layers of carbon fiber, and unless you employ destructive testing, then you will never know. The outer layer may be just cosmetic.
