Trouble routing brake cable through top tube

I've got a mid to late eighties Pinarello Treviso, and am having trouble routing the rear brake
cable and housing through the top tube. I'm assuming that the entire housing goes through the tube,
perhaps I'm in error. The two openings are rather small; I can only get a 4mm housing into the first
hole, and it's a tight fit. When I try to get the other end through, I have had no luck at all
meeting the opening. Is there something I'm missing, or a method to this that I'm not aware of?
Perhaps there's some sort of ferrule that adapts to the openings, and only the cable goes
through?Any insight or suggestions to this would be most appreciated; other than this snafu, the
bike is ready to ride, and of course I'm getting anxious. Thanks in advance..... Greg

I had this last year on a Giant TCR frame.I tried at least 4 different outer cables from different
shops, and finally got one that did fit through the hole. I already had some genuine Campag brake
cable housing, and this fitted through the 2 holes easily,but it was just too short. I think you'll
need to go round various shops and measure the diameter of the cable outer.Cheap stuff is thicker,
and seems to be what all the shops (round here at least) stock. Alan.

I had the same frame and only fed the cable through the top tube. Isn't there a ferrule thing that
acts as a cable stop when entering and exiting the top tube. I flipped the frame upside down so the
holes were on the bottom and fed the cable through after less than 10 attempts. I never thought
about feeding the housing through at all - just the cable.

I suspect there are several variations here, but my late 90's Jackson has a tube connecting the two
openings. I put a ferrule on the end of the cable housings which butt into the openings in the top
tube. The actual cable simply and easily threaded through.

My Merckx TSX Century (circa 1989) had the rear brake cable internally routed throiugh the top tube.
It would not take the brake cable housing, as it was intended to have metal step down ferrule that
went into the two exposed entry and exit stubs on the top tube.

Rather than put a metal ferrule on the painted portion of the stubs, I measured the depth of the
stubs and cut off the protective plastic housing from around the ends of the cable and inserted them
into the stubs. Didn't get any paint scratching, got good braking performance, and the set-up looked
neater than haviung a metal ferrule sticking out.

went into the two exposed entry and exit stubs on the top tube and only the brake cable itself
inside the guide built into the inside of the top tube.

Rather than put a metal ferrule on the painted portion of the stubs, I measured the depth of the
stubs and cut off the protective plastic housing from around the ends of the brake cable housing
that same length.

This allowed the short exposed metal portion of the brake cable housing to fit into the stub and the
plastic portion of the full housing was flush with the end of the stub.

Didn't get any paint scratching, got good braking performance, and the set-up looked neater than
having a metal ferrule sticking out.

The trick (at least with my Kestrel) was to pull the old housing out while following it with the new
housing. Run a brake cable thru both housings before you make the attempt (to hold everything in
line). A lot less frustrating. Steve

If you haven't done this and the old cable is out, then try this: Run the housing in with any old
brake cable. When you see the cable through the opening on the other side, fish it out with a paper
clip, pull on the cable with some pliers and the housing will follow.

I take the housing, put a wee kink in the end to point it 'down', then use the housing to measure
the exact outside distance between the two holes. I then feed the housing into the frame and the end
finishes up in the general area of the exit (but at exactly the right distance). Then i use a
sharpened spoke to guide it out to daylight - Ъ×
