What is the material that is used on the axle sockets for the front fork and rear wheel? I notice Scott uses aluminum glued to the carbon fiber frame. On the TCR Comp 1, you can't tell as there is no visible junction. It appears all carbon fiber. If there are Alu tips, then it must be coated with a carbon fiber layer, or the paint on the frame is pretty darn thick and durable. The serrated surface of the skewers don't seem to scratch it.
