Could anyone post a picture of how exactly should I set up the cables under bottom bracket when a mechanical groupset is used (Dura-Ace)? I'm not sure if I got all parts with my frame. There are a bare carbon grooves, but I'm not sure if any plastic cable guide screwed in to the frame is used or not, like on the previous generation Tarmacs? I would really appreciate some help.

I may not be the best person to help as my memory ain't what it used to be, but I seem to remember that my Sworks Tarmac SL4 when I had it running mechanical was just a kind of grooved bare carbon guide area in the bottom of the BB that you could cover with a carbon plate. So no guide that I can remember.

Here's how it looks inside. I am still not sure if I should run any sort of plastic guide screwed in or there's no need for it and I just use the carbon grooves.

Yeah, just use the grooves. There's nothing else. That threaded plug is to take the cover.

I smeared my grooves with light grease to help it run smoothly.
