Why is this so fugging hard???????  Had to install a bunch of foam surrounds to my internally cabled Whyte 905 because it won't stop fugging rattling and now, I cannot get the internal seatpost installed due to the stupidly small whole at the bottom of the seat tube.  Not looking for an answer really, just venting. Apologies and I hope your wrenching is going better than mine 😡 🤮

Calm has returned

Good to hear. All sorted?

I had to reinstall the Reverb seat post in my Canyon several years ago. It was not as easy as I’d have liked and that was, mostly, externally routed. Despite this I still ended up having to rebleed it. Very pesky.

I'd similar with the Mega trying to feed multiple hoses in including their foam sleeves, of which ytou pretty much have to do two of the sleeves at the one time and as you say, the holes are rather tight for such a job.

Mine ended up in disaster though. I fed in the brake hose(rear to front) then when trying to grab the end of the hose with needle nosed pliers, the bloody things slipped and gouged the black outer casing. Means I need to replace the entire hose, made more difficult given the foam sleeve is already in there, and the only way is to join the new hose to the damaged one and try to feed that through so it passes through the sleeve as well.

 

Im considering buying one of the park frame feeding tools, even though its a bit pricey for what it is, but might stop me tearing out whats left of my hair 🤬

No idea as I've not tried it myself, but would an electricians fishing line do the trick?

I was looking at the routing on my Cannondale.. was thinking if I ever wanted to change brakes or dropper (or indeed, upgrade to mechanical shifting (I hate the electronic crap)) it would be bleedin impossible. The only instructions anywhere are a diagram with the cables colour coded. No clue how you actually go about feeding them through the frame into the cable holders which are INSIDE the frame etc. The bike industry is insane.

One of the Rockshox little red cable joiners may help? you can join hose or cable seamlessly: Barb Connector

Also (just ordered) ebay version of the Park feeding kit is less than a tenner.

There is a lot to be said for bike manufacturers who design their internal routing well (or simply avoid it).

My Vitus frame had fantastic large holes at the headtube which allowed for easy grabbing of cables fed from the rear and easy addition of foam insulation. They supplied a nice plastic cap which also had space for a zip tie to further prevent rattling.

My Signal Ti has fully guided internal routing. Perfect.

While it's not perfect, I still feel like the external routing on my Airdrop is an upgrade.

This works quite nicely for joining hoses together to pull a new hose through with the old hose.

I got it through in the end. Only to find that the seatpost actuator had disconnected itself........Never been closer to savagely attacking a bike frame. I remembered I had bought a "threading" kit off fleabay and it did help.  2 hours and a bit more to install the brick hard rubber grommet.  I should be easier than this 😀

TBH I got my Park internal threading stuff from Amazon warehouse(I reckon someone did the job and returned it), you’ll always begrudge the price but it’s one of those things that having the right tool makes working with internal routing a much more pleasant less harrowing experience.

I think that and my airshot are some of the tools that just make life so much less farf.

I bought the specific rattle foam which didn’t really work.

So I dropped the forks and stuffed a pair of tights down the frame tube. Worked perfect .

Well I really hope I don't have to do that job again for a loooong time but yes, I'll buy the Park kit before I attempt it.  Re the specific foam, this was the second attempt. I does seem to be hit and miss.  I'll see if Mrs Penguin has a spare pair and try that if this one fails.

Males sense with everything ending up a tight fit.  I wonder if bike shops may start stocking this solution?

Yeti. That's all I'm saying. When Yeti owners get together they all have the same hollow eyed terror when sharing their experiences of dropper cable routing. With the switch infinity link getting in the way as well, it's a truly horrible job.

The only instructions anywhere are a diagram with the cables colour coded. No clue how you actually go about feeding them through the frame into the cable holders  INSIDE the frame 

My tip would be to take a nice bike ride down to your LBS, hand them a suitable quantity of great british pounds, and then retire to a cafe with a book for a liberal application of cake and coffee (to yourself, not to to the book). Life's too short for this kind of stress

I have decided that I will never buy a frame that doesn't have "integral" cable routing where it's guided from one end to the other and where all you have to do is push the outer or the hose at one end and it comes out of the other in seconds.

My Revel Rascal is like that but I assume plenty are similar. The fact that I only paid £700 for it despite it being mint is just a bonus, I'll happily pay far more to enjoy the sound of silence and the near zero hassle when building the bike.

It would be really hard to go back to a worse routing.
