Curious to hear if anyone has a theory or actually knows why back in the day some bikes were built with cable guides for the rear brake cable, other bikes were build with cable stops atop the top tube and other bikes were built with cable stops under the top tube.
There are many ways to skin a cat and apparently just as many ways to route a brake cable.
Is there a benefit to 3 cable guides on the top tube and one long continuous housing? I would guess compression reduces effectiveness, though I can't say I have noticed it much between bikes.
Looking at it from an economic perspective, the cost of 2 cable stops can't really be more than the cost of 3 cable guides, right?
Cables routed on the top of the tube make sense if the bike is meant to be carried(cross for example).
But other than that, what was the benefit to full length housing and cable guides instead of using cable stops?
