[Closed] Pulling new cable outers through frame

In theory this should be a breeze - just attach the new outer to the old one and watch as it effortlessly slides through...

More often than not though, I screw it up, and the two cables become unattached, or jam in some way at the join. Can't seem to do the 'slide it over an inner' trick either.

Anyone got any hints on the best way to secure the two ends together or generally manage it like a pro?

Most simple way is the slide over the already installed inner I'm afraid, may just take a few twists and wiggles to get through any tight spots.

Had a similar thing at the weekend swapping out the dropper cable on my bike, remembering it being a pain to do first time round.
I managed it by using some electric tape to join them together at each end and carefully push/ pulled the cable through.
After a couple of nervous minutes it worked ok.

I did similar to what you are describing. I pushed the inner cable through the new outer and in to the old outer and then wrapped a single layer of selotape round the two outers to keep them together. You want to push the cable through rather than pull it through. This all worked fine for me.

There are joiners that you can buy to join the old and new cable together but I didn't bother with those.

Reverbs used to come with a double ended barb for just that purpose, I have a couple in the box and it makes attaching the new cable outer to the old sooooo much easier and secure

Yeah, always meant to get one of those, but normally only remember to do it on the day I have to replace an outer. Then forget about it as soon as the job is done!

What should be a really easy job if frames were made properly if they insist on internal routing. Proper internal guides should be an absolute must.

I had to replace a gear cable on my Eeb at the weekend. It ended up taking hours (party as you have to take the whole bike apart to do it) but also not helped by appalling internal routing.

It was enough to make me go & buy AXS.

I don’t know why we can’t just have external cables.

I had this on and awkward frame.
Used a Small threaded screw, cut the head off and file to a point. Screw both cables onto it, cut the screw damaged cable end off when it’s through.

Long length of Heat shrink also works.

Shopping just after rage-chucking tools across the workshop is never a good idea 🙂

Might try that screw idea, cheers.

Double ended barb makes it a 2 minute job. Life is too short to faff about filing screws down. I’ve got AXS too now and would never go back, but the barb is still needed for brake hoses...

Well, despite all my whining, that was surprisingly easy today. Almost tempted to head back in and swap the gear outer too. 🙂

Even worse is needing new olive/barb and cutting hose every time you swap or remove a brake

Sram barb connecter thingy if you've already got a cable in there.

New bike is internally routed (Rail 9) and not looking forward to changing cables, going to be a shitter of a job by all accounts. Might invest in the park integral routing tool.

I use a 3.5M long tandem gear inner wire.
1. Pull old inner out and thread tandem gear inner in.
2. Pull off old outer cable, hanging onto to gear wire..
3. there is enough lenght of gear wire that you can thread the enitre new outer over the gear wire before it even goes into the frame. Once the gear wire come out the far end, you clamp the gear wire to the outer and pull the whole lot through.
