About The Drivetrain

The Drivetrain is an independent publication about the parts that move bikes and the markets that move around bike racing.

We started from a simple observation. In cycling, more than in almost any other sport, engineering and results are tied together, and results are tied to money. A drivetrain that saves a few watts can decide an Olympic final. An Olympic final moves betting markets. And the same drivetrain, scaled up for heavy loads, decides whether a delivery fleet's bikes stay on the road through a race-day rush.

What we cover

• Tech: chains, sprockets, efficiency testing and wear, explained without marketing.
• E-Mobility: e-bikes and cargo fleets, cost of ownership and reliability.
• Racing & Odds: keirin, track cycling, the Tour de France and the history and practice of betting on bike racing.

Independence

We are not a manufacturer, a retailer or a bookmaker, and we are not affiliated with any company whose products we discuss. Where we mention commercial technologies, such as the Enduo dual-engagement sprocket developed by New Motion Labs, it is as independent coverage. Trademarks belong to their owners. We may earn a commission from some links to retailers or betting operators; it never decides what we write.
