Prototype Internal Disc Road
I built this a few years ago, it was fun to experiment with a different form of internal routing, through the headtube. It's a bit awkward as there's not much room in there, but I really like the cleaner look. I also opted to use a T47 bottom bracket shell for more crank options.
It's all @columbus_official tubing, with a GX shaped spirit downtube and Futura disc fork. I like using the shaped tubes despite being slightly more difficult to work with.
