best installation for 2014 Trek Speed Concept

[Rick]

I mounted my Newton between the aerobars just before the point where the bars angle up. I am wondering what the best way is to route and fasten the tube? I have tried sort of an S curve by taping it with duct tape to the bottom of the base bar. I don't like this as the tape is tacky looking, not entirely stable, and leaves hard to remove residue. I haven't resorted to zip ties as I fear I would have to use a lot to create a stable end point on the base bar. Anyone cracked this nut?
