150mm Crankset: A Custom Setup for Your Bike 🚴♂️
Cranksets with 150mm crank arms are rare on the market, but we've selected the Rotor Aldhu 30mm, the benchmark in modularity and performance. While our offering focuses on this single model, it’s because it allows for full customization, suited for both road and gravel riding.
Thanks to a fully modular system, you can configure your crankset to match your needs and riding style:
✔ Axle options: standard road or gravel-specific offset.
✔ Chainrings: round or oval (Q-Rings), in classic or aero versions.
✔ Spider: standard, aero, or with integrated power meter.
✔ Spidering: available in 1x or 2x versions for optimized transmission.
✔ Bottom brackets: carefully selected for performance and perfect compatibility with the Rotor Aldhu 30mm.
🎯 Why choose this setup?
With a 150mm crankset, you benefit from improved pedal control, reduced muscle strain, and a smoother pedal stroke — ideal for riders seeking a high cadence and efficient pedaling dynamics.
