Hidden cables – how the hell??
Do I change them? Im trying to replace the front mech cable on my Canyon, the cables are hidden within the frame, and having spent 15 minutes blindly stabbing the cable down through the frame im no closer at all the getting it into the guide under the BB. It just seems to disappear within the frame. Is there a technique that im missing or is just hit and hope?Posted 4 years agoBadlyWiredDogSubscriber
Cable liner threaded over the old cable before removal, take out old cable, then thread the new cable through the in situ liner – that thin plastic sheath stuff that’s only slightly bigger than an inner cable – then remove the liner leaving the new inner in place. But it’s too late for that now…Posted 4 years agopiedi di formaggioSubscriber
Right, when you got your Canyon, you will have received all sorts of manuals, bits & pieces, etc. One of the things you got was a long thin plastic tube (nows the time to regret throwing that way).
To replace a cable, you disconnect the mech end and remove the outer and ferrules from the mech end but DO NOT remove anything else.
Next use that thin plastic tube and push it over the inner. Push it on as far as it will go. Then tease out the ferrule and outer from the bar end exit from the frame.
Push the inner AND the plastic tube so it emerges from the frame. You should now have the plastic tube and inner showing BOTH ends of the internally routed cable.
Next carefully pull the inner out of teh plastic tube, leaving just the plastic tube in teh frame with the ends hanging out both ends. Remove rest of inner & outers.
Now, put a new inner in the shifter and add furrules and outer for the ‘bar’ end of the cable rtun. Push the inner through the plastic tube until it emerges out of the other end of the plastic tube.
Pull the plastic tube off and finish cable fitting.
Store the plastic tube safely for next time.

As you’ve already gone past the point of no return, I’d suggest using an alternative but more pliable material to get a chaser through the hole.
String is much easier to vacuum out of a hole than a gear cable!
Once you’ve got your chaser you can start to use the methods above fixing your new cables to the string and pulling back through the framePosted 4 years agoshandcyclesMember
A length of inner cable with an *almost* 90º bend tweaked into it about 30mm from the end works well. Feed the cable through then you can rotate/spin the cable until the cable starts heading in the right direction. Small needle nose pliers to grab it will help too. Ben’s thread and hoover trick works well too.Posted 4 years agomcnultycopSubscriber
I have a Nerve AM and to get the rear mech cable through I had to strip the front mech cable off fully and drop the little plastic guide thing out of the frame – this revealed a larger opening and the whole thing was then really easy.
I then went 1×10 as I couldn’t face messing around with the front mech any more!Posted 4 years agoD0NKSubscriber
I’m quite impressed with the amount of people who’ve said “this is how you should have done it…//…but that’s no good to you now”
in the same vein…what you should have done is not buy a bike with internal cabling. 🙂
are cables and spokes magnetic? cable in one end, strong magnet on spoke, push spoke through other end try to “attract” the cable?
Ha did it.
well done, this ^^^ is no good to you now then 🙂Posted 4 years agodickyhepburnSubscriber
Did same thing – my solution = much swearing, then took the bottom plastic guide completely out, shine a bright light up into the frame, feed old wire down into frame, look for it and use wife’s tweezers to grab it, then use this as a guide to feed outer over wire etc as normalPosted 4 years ago
Taking out the bottom plastic guide really helped!ScapegoatSubscriber
Bike in stand as high as you can get it, remove guide from under BB, angle frame so it’s almost vertical, thread cable in, use a torch and tweezers to fish the end of the cable out. Swear profusely and keep trying till you get it. Remove BB foe extra faff and swearing opportunities.Posted 4 years ago
I basically just stabbed the cable down frame many, many times. The law of averages stated that it had to come through at some point. Of course I was so shocked when it came out the right hole the first that I pulled it straight back out again. Thank God the kids weren’t in the garage with me, they would be in counselling for years with language I spewed.Posted 4 years ago
