Something like that would foul with a handlebar roll.
My best bet would be to go with a torpedo style bottle holder and then just molish a bar/banana sling to fit under it. How far apart do you usually have your bars?
The audax bike is quite wide (because I'm too lazy to finish filing down my light mount bar).
The TT bike is maybe just wider than a bidon. I don't have a handlebar roll (at least, I don't think I do)
I see what you mean.
