"Back in the day" we sold quite a few Fuso frames from Dave Moulton. Had very good success upgrading customers to the internal routed brake cables. When we sold a frame with the conventional brake cable guides, Dave gently chided us (in good fun). That customer promptly hit a lowboy trailer in the dark and folded the front triangle. It was sent back to Moulton to replace top and down tubes...and this time customer sprang for the internal routing to boot!
