If a bike is going to live with me, it’s not going to be a toy. I want my bikes to be practical, reliable, safe, and fun. Adding dynamo lights on my bike accomplishes all of these goals. So when I designed my new frame I wanted to integrate my dynamo lights as much as possible.
Although it would have been nice to buy a new set of lights for the bike – the Son Edelux II and the Compass tail light are particularly alluring – I decided to reuse my Supernova lights. On my previous bike, I strapped the Supernova tail light to my seat tube with the included rubber o-ring. This works just fine but it looks sloppy. So when I designed my new frame that I built with Dave Bohm, I wanted to ditch the o-ring and connect the tail light directly to the frame with the wire running inside the seat and down tubes. Running internal wires adds complexity to the project, but when done well it looks cleaner and prevents the wires from getting damaged.
The Supernova headlight will simply be mounted to the dedicated arm on my Compass CP1 front rack with the wire running externally from the hub, along the inside of the fork blade, and then along the lower rack support tube to the light. If I had more skill, or maybe just more bravado, I would have drilled and reinforced holes in the fork blade and run the wire internally. While not as clean, the routing option does make wiring a bit easier.
