Rotor offers you the chance to create a bespoke model and boost your performance. You’ll have complete freedom in choosing your components to build the crankset that suits you best! Whether you prefer round or oval chainrings and whatever your crank length, Rotor lets you customise your crankset from A to Z.
Victory at the end of the cranks: the Aldhu model offers solid stiffness for optimal power transfer, ensuring not a single watt is left on the roadside. If you’re looking for a more affordable option, the Vegast cranks offer an excellent balance between stiffness and budget!
Performance delivered through the chainrings:
- Oval chainrings: their oval shape makes it easier to pass through the dead spots and engages more teeth in the power zone under load.
- Classic round chainrings: a wide range of gear ratios to suit all terrains.
Compatibility and modularity right down to the teeth: you can fit chainrings compatible with your SRAM 11- and 12-speed AXS or Shimano Di2 11- and 12-speed drivetrains and optimise your drivetrain.
The bottom bracket: its 7075 aluminium construction makes it both lightweight and stiff, weighing less than 100 grams. An attractive option for the lightest builds.
The centre star: Spider Mount design with separate chainrings and centre star to offer modularity and versatility.
