When did bike manufacturers start routing rear brake cable internally through the top tubes of bike frames?
I generally thought it was mid 80's, but that's just from seeing loads of frames from that period with it, but for all I know it may have been tried decades before this.
Anyone know? Is anyone credited with doing it first, if so who? Was it something that originated in the pro-peloton for aero, aesthetic or other reasons, or was it something that started happening by many frame builders at around the same time?
