What am I missing here? (Rear brake cabling)

Re-cabling this old Specialized HardRock and Iím having a conundrum with this rear brake cable as it goes from the cable stop behind the head tube to the cable guide on the seat post collar (cantilever brakes).
The cable stop behind the head tube is clearly designed to not include a cable continuing along the top tube toward the back because itís rounded off with no insertion point.
I put the little rubber bumpers on the bare cable to avoid it scratching the top tube, but when the cable gets to the cable guide at the seat post it brings the cable out all far from the frame it looks odd and the bumpers donít even touch it.

Iím not sure if I remember pulling off some sort of housing from there during tear down but maybe I did? Even if there was how would it also not float out there given the angle of the cable guide entry point on the seat collar?

Heres some pics:





Maybe someday the forum software will learn how to accept portrait oriented phone pics- sorry they are sideways...

Yeah itís all part of the frame itself.

As others have said, the cable just goes through the tube that is welded to the frame and straight to the hanger. Thereís no other stop. Itís not a bad feature but it will be a pain if you ever want to put on linear brakes.

A couple inches of cable liner inserted in the channel would reduce friction. But, no, it's not necessary.

Speaking of which, feel around the gray colored collars that surround the brake return springs. Have the collars on your bike cracked yet?

I have several Rockhoppers with the same feature. It works well. I've taken to using cable liners instead of those rubber donuts to protect the paint. Those donuts seem to just bunch up in one spot anyway.
