Billy, I would STRONGLY advise you to NOT use SIS housing for brakes. The force put on brake cables is considerably more than derailleurs and WILL at some point cause the housing to explode. There is a reason the brake cable housing is coiled and the derailleur housing is straight. Brake housing is supposed to compress slightly, which allows for some modulation. SIS, on the other hand is designed not to compress which allows for accurate shifting. Using SIS housing for brakes is an extremely dangerous proposition. Keith

I recall asking Gary Page at Turin Bicycle Co-op in Evanston about a bike s et up this way, back in the early '80s. He said part of the trick was
to use very stiff cable housing. I'm thinking that if you drill a hol
e in the back of the body, you're going to have a very short throw so
any c
ompression would compromise your braking action. And if you're going to
dri
ll the bars for internal routing [don't] someone suggested removing the
pla
stic sheath to allow a smaller hole. So, I'd suggest just using SIS type
de
railleur housing. I set up a bike once for a young woman w/ no left hand
by
drilling a small 2nd hole in the Campy Ergo power brake cable pivot a
nd through the body. There wasn't much room so i used SIS housing to the
re
ar brake. I don't recall if i used a brake cable or derailleur cable. If
th
e former i probably had to file down the pear end as it was pretty
crowded
in there. Anyway SIS housing and a thinner brake cable should work for
your
purposes. Good luck. Billy Ketchum; Chicago, IL; USA.
