WTF? These are patentable designs??

I would wonder how you could ever thread a
hose/outer cable through that much of a length of
bike without an actual inside tube.


Depends on the frame and how much impedimenta is hidden
inside. On some, drop in wire or hose, catch it in one's
fingers through the big hole in front of the BB. For
many,
neodymium magnets and a stiff poly wire are the quickest
solution. Others need something to pierce the swarf
inside
like a 1/16" welding rod. Then there are the odd
frames now
and again which just resist cable/hose installation
for no
good reason and tick off the mechanic.

Typical tool:

If you're doing a bare frame, it's a PITA but not
horrible. It is horrible if you're trying to snake a
Di2 wire or hose or cable through a crowded DT into a
little passage under the BB with existing
cables/hoses/wires. And let's see what's behind door
number one! https://tinyurl.com/yy9xwxwb This is the
great time suck with modern bikes -- along with hidden
nipples in pre-fab wheels and a few other annoyances.

Last week I replaced for the first time the inner
cables of the front and rear derailleur of my internal
routed Canyon frame. It was very easy. The frame has a
big removable plastic cap on the bottom of the bottom
bracket shell with the cable guides integrated. I
removed the cranks and put a liner (a piece of the
smallest shrink tube) from the RD side over the old
cable to the BB shell in the horizontal chainstay.
After that it is a piece of cake.

Changing a cable isn't terrible. On my Norco, for
example, the RD cable is all in housing. Installing the
housing is a PITA getting it through the chain stay, but
once in, cable replacement is easy. The FD cable is in
housing from the lever to the DT, but then it stops and
runs bare through the frame. My technique for running
the FD cable is to pull the old cable just a bit out of
the lever, cut off the button, pull off the outer
housing and then I cut off a cable end cap so it has a
hole in both ends, put the new cable through the lever,
through the housing and crimp it to old cable with the
cable cap and then just pull it through the frame. The
openings are big enough to accommodate the cable cap,
and then I just clip it off since there is so much
excess cable anyway. I suppose I could use shrink wrap
to join the cable for the pull, but I've never tried
that. Running a new hydraulic hose or cable housing can
be a pain depending on the frame and circumstances. My
worst experience was running a new hose through a
Roubaix when I couldn't use the old hose to pull because
the meth-heads who stole the bike (the police brought it
back) had cut the rear tube and shoved the end in the stay.

I don't doubt that there are many clever ways of fishing
cables through
frame tubes. But isn't it amazing what people will put up
with for
aesthetics?

Well, lets see this was the first time I changed the
cables in 5 years and it went pretty easy even with the
removal of the crankset which is also pretty easy with the
modern cranksets. So I think I can live with this little
inconvenience for a cleaner look. Personally I find
touring bikes incredibly ugly with all that bolted on junk
but I don't have to ride one so I won't make a remark when
it pops up here.

Tastes vary, of course. And they're greatly affected by
one's personal interests.

When I was young, just discovering bicycling and a bit
interested in racing, I thought the most beautiful bikes
were pared-to-the-minimum racing bikes. But after a while,
those all began to look the same to me. (Yawn - another bike
with spider web wheels and holes drilled in the shift levers.)

These days I'm more likely to stop and inspect a well-used
touring bike or cargo bike, especially if it has custom
features. Modern racing bikes look so... well, so plastic!

But I do think steel frame fixies look cool. Now _that's_
minimalist!


When we were young, top racing bicycles were notable for
having no brazed bits, unlike 'cheap' ten speeders. The
popular theory was that brazing a bottle or shift mount
'weakened' the frame. So the popular aesthetic was a pile of
sloppy steel clamps with crappy screws. That changed.


Thank Buddha for that change. My PX10 was clamp-on everything except for the chain stay cable stop. I guess it was O.K. to heat up chain stays. The chroming was probably more destructive.

I don't care about the aesthetics of cable runs, although I wasn't that excited about the cable slap on my Cannondales with the bare cable run along the top tube -- and the little rubber doughnuts that all seemed to migrate to one end of the run. Internal hoses can rattle too if you don't pad them.


I guess I entered the game near the end of the braze-on "prohibition." I
still remember the first time I saw a custom-built frame. I thought the
brazed on guides were a great idea.

Our tandem has a long, long bare cable run along its top tube. I used to
get a little irritated by the quiet ringing sound when it slapped the
frame. It doesn't seem to irritate me now, even though I have no
"donuts" on it. I don't know if I'm more tolerant, or if my hearing is
going.
