Would like to ask how the tubing for the hydraulic brakes are run. Are the tubing hidden inside the carbon fiber frame? If so, what happens if/when there's a leak? The hydraulic fluid will be trapped within the frame. How does one go about cleaning it out and re-filling the hydraulic line? Is there a drain port somewhere in the frame?
The hydraulic line is a bit thicker than most cables. If it needs to be replaced within the frame, how does one go about it?
On the disc brakes themselves, can you advise the size of the discs for the front and rear wheels? What is the largest size that can fit on the calipers? What material are the pads made of?
