Thinking of buying these Renthal aluminum bars.
http://http://www.dimecitycycles.com/7-8-inch-silver-aluminum-ultra-low-renthal-superbike-handlebars.html
First Question... These bars seem to have less room to pull electrical though interior of bars after i drill some holes. Has anyone had problems with this.
Second QUESTION...Did anyone have any grounding issues with this anondized aluminum?
Any info will be greatly appreciated....
I have LSL "Superbike" bars on my XS. However, all my cables are running on the outside.
These LSL bars have 4 mm wall thickness, so internal diameter is around 14 mm (9-16")
I do not know if drilling holes in an alloy handlebar is a good idea, but could possibly be done. As I have mechanical engineering background, I would like to give some advise on this:
I would definitely locate the "exit" hole BETWEEN the handlebar clamps/risers. This because the highest bending stress occurs just outside the clamps.
Then, if you imagine a straight line from your shoulders to the handlebar grips, as you sit on the bike with straight (locked) arms, like when braking hard. Any "entry" hole should be at 90 degrees to this imaginary line. This would put the hole a little bit forward of the top center of the bar, or aft of the bottom center, exactly how much fwd/aft is depending on your height. This puts the hole at the bending neutral axis, having minimum negative impact on stiffness and strength.
Anodised alloy har poor conductivity, so for horn button or other switches requiring good ground, you could glue a piece of thin copper, stainless or similar to where the switch connect, then run a ground wire to the frame. I guess the stock rubber mounts isolate the bar anyway.
A neat, but expensive solution for minimal and hidden wiring would be to use a Motogadget setup, with Can-Bus connection between a "m-button" inside the handlebar and the "m-unit elecrical central". Then you culd use thin gauge cables between handlebar switches and the "m-button"
Not cheap, but very slick! Links are to English product pages!
