Internal Cables mess
I finally got around to swapping new cables and housing on my Wilier 2013
GT. I had 4000 miles and shifting was ok but thought maybe change before it might break in the Shimano 6700 shifters. Well sure enough I get in a hurry and end up pulling everything out and 4 hours later managed to get it all back together. Next time I will simply cut the old cable at the side that come out to the handlebars, run the new cable through the shifter, then splice the new to the old with heat shrink tubing, and carefully pull it all through. Does anyone have a better way? My question is if the small tubing that run through the frame is really needed. I realize it suppose to stay so you can thread the cables easy but it can wear out too, and I find in the rear stay it was binding the shifter for precise shifting. I remove the inner tubing in the that runs through the chain stay and just plain jagwire cable bare ( of course internally) and instantly I dialed in very good shifting. So do you really need the inner tubing? I suppose as long as I can thread the cable through the frame no need to bother with the inner stuff. The housing for the brakes does not go through the top tube it has the same deal but that is pretty easy to thread. Does the small tubing help shifting and I will tell you I have could have easily built a set of wheels in the crazy time it took to get the cables through. I should have been more careful and googled solutions before I started. I like to know what the pros do here. Deacon mark cleary |

Internal Cables mess
Andrew,
The inner lining is white tube appears to be plastic. I cut a piece of derailleur housing apart to get what I think is the inner tube stuff. This goes between the BB and the chain stay going out to the rear loop. The inner tube material ends as it exits the chain stay. Then the wire exposed for about an inch as I goes through the final out with has a ferrule and the rear loop going to the rear mech. Some have the wire coming out the side of the chain stay but on this Wilier it exits right out the end of the chain stay. In any case that was a hard threading and once I got it all together I notice the shifting was not so going upshifting but ok downshifting. Well I decided the inner tube material was causing the shifting to bind a bit. I removed this and bingo, the bike started shifting fine. So now I have a rear cable only in the chain stay no inner tube and after 3 rides and over 100 miles ( including 44 this am at 28 degrees) the bike shifts perfect. I did not mess with the front cable this seems fine and the front shifting is spot on. I did look up the Park IR-1 tool that is was recently put out specifically for internal routing and change cable\housing easy. That looks pretty good and may have to invest in getting it. I am basically little OCD about shifting and I want the puppy to shift perfect no misses. I do the routine maintenance and keep things up, I would rather swap out and cable and housing especially the rear loop that goes bad first and not try and save pennies. Seems to me that doing this I get much better shifting all the time and no hassles on the road. The only thing is my other bike has the usual external cables and they are fine by me. I can check the tension easier and frankly these buried routing under the bar tape is really not better. My other bike has DA 7800 and it smokes never an issue and easy to change cables and housing. What is the splicing double ferrule you are talking about to make the spice when running the old as a guide for the new cable. Finally one last question. I currently have Shimano 6700 and thinking about upgrading to 6800 11 speed. My wheelset I can use 11 or 10 speed I have a spacer in it now for the 10, so that is not a problem. I hear the 6800 stuff in really much better and frankly some good prices for the group. Is it really that much better? In any case thanks for the help the old deacon appreciates it.

There is a double ferrule for that or just change the casing and rewrap with fresh tape. At 4K miles, new tape would be a nice thing anyway. Do you mean the smallish 3mm OD teflon tube? That can wear and abrade and may also be too short or long so changing it may be indicated. If it shifts well without an inner liner it's probably OK but I don't know what the inside of your frame looks like. If you meant an installation aid, yes, small vinyl tube (hardware or hobby store = RC fuel line) is very handy for changing internal wires. Slip it through over the old wire, change wires, withdraw tubing. -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 |
