Internal cable problem
 

Probably this not the last question I have about my new frame.

Here is the problem: The cable housing does not stop, but goes deeper and deeper inside the frame.
Please, see picture. It is hard to explain, but I will try:

I have ran the cable through the inner tube, and put cable housing with ferrule on. But as I slide the the housing down, it does not stop. As you can see on the picture the hole in the frame is larger than the ferrule. The internal cable housing is a plastic sleeve, but not the small, it has large diameter. I have inspected the best I could the the metal plate from the inside, and I found that the 3 internal plastic tubes runs to each hole. One of them is attached to the metal plate from the inside (the top one on the picture - it runs to rear brake, and there is no problem there - you can see the plastic tube in the hole)

But the two other plastic tubes are NOT attached to the metal plate from the inside. I do not know how did it happen, the frame I bought was used. I believe that the ferrule should be stopped by plastic tube. But I cannot fit it from inside of the frame into the hole on the metal plate.

Please, advise what I can to to fix the problem?
Thanks

Can't say for sure but some internal brake cable setups have the outer casing going all the way through the frame. There are no stops with bare inner cable in between. The outer goes all the way from the lever to the caliper.

Contact the manufacturer, whoever that might be, for the information you need.
Waiting for someone on the forum who had the same make & model to respond may not be as efficient as an e-mail to the manufacturer.

This is Argon18. I already sent them an eMail

If I am reading this right it is cable housing all the way and won't have stops.

It's kind of obvious. Unless there's a stop, and some kind of system for leading the inner wire out aligned with the axis of the tube, and a corresponding method for the inner wire to exit at the other end, the housing must go all the way through.

It's easy enough to know by looking a the exit hole, and if it too is 5-6mm in diameter, that means housing in/housing out.

You are absolutely right, I just tried to run housing from the bottom hole and it came right out where it should.

I was just overthinking it, because so used to external cables. What you said makes perfect sense. Thank you very much.

Then, another question, should I lube the housing as I run it through, and what lubricant to use?

There's no need to lube the outside of the housing because other than you sliding it through, it doesn't move in the frame. In fact, many owners of frames with this configuration find the housing to walk changing the loops at either end in ways they don't like. I have a friend who ended up putting a dab of hot melt glue at one end to stop the walking.

OTOH- if you ride in wet weather, the housing ports are entry points for water. This makes a weep hole in the BB mure critical than otherwise. Besides the weep hole, I'd consider a bead of silicone caulk around the top tube entry point as a weather seal.
