The beauty of the bike is, IMO, the mechanical simplicity. I assembled it, I maintain it and I diagnose it if something goes wrong. When the shifting is buttery smooth, that's me, not some software engineer at Shimano or SRAM. I also drive stick shift cars and wear a mechanical watch - that's just how I like it. Are these the most efficient? Probably not, but there's more to life than efficiency
