cable routing

I am routing the shifter cables inside the down tube. The cables will come out of the bottom bracket. I would like to know if brass guide tubes are used and what this would look like. The rear cable stop is going to be under the chain stay. I have seen this bottom bracket set up out of the bottom bracket on fliker some where. There were no pictures of what it looked like inside of the bottom bracket though.

see if you can find tubing to let you use the plastic liners out of V brake noodles
for lower drag.

Good discussion of internal cable routing here: https://www.velocipedesalon.com/forum...ons-14099.html

One suggestion for guide tubing is to use automotive steel brake line. Its suggested to buy 1/2 in, but I recently bought some and found the internal diameter to be too small, had to be 5/16 in.

unit translation error? I think 9/16 would be big enough to fit 3 sets of housing through.

I think the OP was talking about shift cables. That's a whole different animal than TT brake lines.
I use an internal line for the rear brake regularly.

Please just make your cable routing easy to maintain the cables. I am so sick of hassle prone internal routing. More friction and more need to replace at a higher time investment. And let your customer that he will expect to pay much more for the cable service when he takes into a real shop. Andy.
