Tool for internal cable routing?(13 posts)

Tool for internal cable routing?lemmy999

Is there a special tool needed to route cables internally? I have a Klein Quantum Race with internal routing and was wondering if a tool was needed and how/where I would get this tool.

... Kleins generally come with plastic internal guides... that can be removed once the cables are installed (I kept my guides for future maintenance)...

Another "trick" is to push some string into the hole(s)... then using the hose from a vacume cleaner... suck said string out the appropriate ummmm, other hole... attach cable to end (perhaps with a small drop of Super Glue)... then (gingerly) pull back through.

attach the string, cable etc. to the old cable before you pull it out. Then it would just pull through with the old cable.
That's what I doDave Hickey

Leave the cable in and pull the housing out. Put the new housing in and then remove the cable.

No kidding, I pulled the rear d. cable out of my Trek's chainnstay without realizing there was no internal guide, and I tried off and on for two years to get a new one through there. I rode the bike meanwhile with a clamp-on housing stop, but whenever I was sitting around with nothing to do, I'd try to run a new cable to clean up the routing. I used the dental floss-and-vacuum cleaner trick, the super glue trick, the piano wire poke, the drill-out-the-exit-hole-a-little gimmick, the run-it-backward-and-solder-the-ends-and-pull-it-back-out thing. When I decided to build up a single speed, I had two or three frames I could have used, but I picked that old Trek just so I could quit thinking about the cable.

I had a internally routed frame.

Put the cable in the housing. Have the cable sticking out of the leading end of the housing at least a few inches. Stick that end in the frame and push it through. When you can see just the end of the cable through the other hole, fish it out with a hooked tool (anything with a hook should be adequate). When you have it hooked, guide the cable out the exit hole while continuing to push the rest through the first hole. Once you can get a hand on it just keep pulling and the housing will follow.

Some frames may be more difficult than others. The size of the hole certainly will make a difference. For a hooked tool you could make one with a cloths hanger or maybe a paper clip. I once used a babseball glove lacing tool. It's like a screw driver with a needle eye on the end.

Just my 2 cents.

Yes, this is the method I have to use on my old school steel Tommasini with internal cable routing. There is no sleeve or anything in mine, The brake cable housing goes all the way through both holes. To complicate matters, the front entry hole is on the bottom of the tube and the exit hole is on the top of the tube. (Boy, taken in the wrong context, this sentence sounds bad!) I have to turn my bike upside down and let gravity direct the cable towards the exit hole.

Why would you want to remove the internal guides once you have the cable installed on the Kleins? Is it just to reduce friction? I am not sure if my bike still has the internal guides in or not. I always figured I could pull cable through if the old cable was still in, but I was worried about the cable breaking inside the frame.

could you use a magnet and some stiff wire/cable? Since the bike is aluminum, the tube wouldn't be magnetic and the wire/cable would follow the magnet.

... I saw the guides themselves as potential trouble spots... and it seemed to make more sense to remove them completely (friction, at least initially would have been minimal... but down the road...) Indeed, once your external housings are in place, the compression loads appear to be transferred diretly to them and the frame's cable guides... simple and clean.

FWIW, I originally thought of trimming the Klein guides and leaving them in place... but that seemed like a whole lot of work!

Also, cables rarely break... let alone inside the relative protection of a frame (If they break at all, it's probably gonna be at one of the ends). The Klein has bare cables inside... so too my P2K... my Manhattan Project has internal tubes permenantly installed... and my GT Vengeance has full length housings through the frame.

Be the bike.

I have Klein mt bike and have recabled it several times. The trick is to pull out the plastic grommet on the side nearest the seat tube. This will make for a dramtically larger hole to fish the cable through. Once you have it through replace the grommet. I spent hours trying to route the cable before a fellow Klein owner showed me this.

Lemmy - go to a local Klein dealer - the bikes all come with a thin plastic straw like cable guide (very thin) - slide it over the cable you want to change, it will follow the cable from hole to hole and then pull the old cable out & replace it with a new one - be sure when you change the frt derailer cable you put the guide on first as that one is very hard to fish through the down tube - with this thin plastic guide the job is very simple - once the new cable is installed remove the guide and keep it in a safe place - it is hell trying to do this without the guide
hope this helps, Ted

Thanks for the suggestions. I will try to get the guides from a local dealer.
