Would you choose a complex dual-chainring system over a simpler single-ring drivetrain for your bicycle?
Startup Marginal Gain has developed the Orient crankset, a system featuring two side-by-side chainrings of the same size. The technology integrates with standard rear derailleurs and cassettes to improve cycling drivetrain efficiency.
Why it matters
The system reduces lateral chain angles during shifting, which minimizes strain on the chain components. This approach aims to boost overall drivetrain longevity and performance by optimizing how power is transferred through the gears.
The Orient system utilizes two side-by-side chainrings to manage chainline, offering potential capacity for 15 to 16-speed drivetrains. Compatibility with existing rear derailleurs and cassettes is currently integrated into the design.
The players
Marginal Gain
A startup focused on developing high-efficiency bicycle drivetrain technologies.
Andre Szucs
The inventor behind the Orient crankset system.
Blackwater Bicycles
A manufacturer partnering to produce titanium gravel frames for the new system.
The details
The Orient crankset functions by managing how the chain moves across the rear cassette. Lateral movement toward larger cogs shifts the chain onto the inner ring, while movement toward smaller cogs forces it back to the outer ring. This mechanical process prevents extreme chain angles, thereby reducing friction and mechanical stress while allowing for higher gear counts.

Health Landscape
This development represents a departure from traditional drivetrain designs like the Shimano GRX gravel-specific groupset by prioritizing reduced lateral chain stress. It reflects a broader trend in engineering aimed at increasing mechanical efficiency in specialized cycling equipment.
For riders interested in hardware upgrades, the full titanium frame and Orient system are expected to retail for under $3,000, while a retrofit crankset will cost under $500. Discuss these equipment changes with a professional bike fitter to ensure they suit your biomechanics and riding style.
The takeaway
The Orient crankset prioritizes drivetrain longevity by reducing the lateral strain common in modern multi-speed setups. Cyclists should monitor the upcoming preorders if they are looking for ways to optimize their gear efficiency.
