Those are all amazing designs. I really like #3.
My only issue with #3 that I thought about later, with a CX bike the cables are on top of the tube, would they chip up that paint?
I love them all! Maybe buy a gaggle of bikes? Paint them different!
went through this myself with my road IF. funny. ended up going a similar direction to your last posted option.great stuff james! when do we get the race reports? have been waiting....layne
