They don’t! But by “playing by the rules” so to speak, I can afford to build just about the best bike money can buy. At least in principle I wouldn’t mind spending $3-4K on a custom made frame, but with no restrictions in terms of weight, design geometry and so on, I would need an unrestricted budget.

Eventually I might go for a custom build , but for a first build the Mash Histogram does seem to meet my criteria, let alone my wallet. In any event I will need gain some mileage to determine what works and what doesn’t.
