Reminds me of an egg cutter if you get where I'm going
I'd be really nervous having my man-candy that close to a couple of highly stressed wires/stranded cables
My son's immediate response also. In closer inspection, cheese slicers and Hardboiled egg cutter are single strand, this will have to be stranded, and if you fell hard enough to do any damage, I think a solid bar would be a more painful experience. Broken cable whip......that makes me nervous.
There would also need to be some sort of turnbuckle to adjust the tension of the wires.
Got that sorted out with some threaded sleeves that will allow tension adjustment. The two prevailing ideas are to measure the frame untensioned, then tension evenly watching for movement; the other is to use a spoke tension guage to check for uniformity. I believe both systems will be employed in tuning the bike. A process that will have to be done before each ride I think to overcome cable stretch and changes due to temperture.
