Well the bolts have nothing to do with hiding the wires since they exit the bars between the risers. In the top pic I posted you can see the braided stainless covering coming out from between the risers.

You can see it in this pic of Wendy's bike too where I hid the wires inside the bars.

I learned all I need to know about life by killing smart people and eating their brains.
