The Rotor Aldhu Carbon Cranks are complete with lightweight, stiffness, and carbon fiber.

With its weight of only 260 grams, the carbon crank arms shave 100 grams for a size of 172.5 mm. When fully built up with 50/34 compact chainrings, the crankset totals out to only 523.5 grams making it one of the lightest weight cranks in the market.

Compared to the Aldhu Aluminum Cranks, not only the weight-saving complements the riders’ performance, but the vertical stiffness is 11 percent stiffer and the horizontal stiffness is 36.1 percent stiffer. The aim was to reduce the weight of the bike without compromising on durability.

Constructed with the Twin Leg Technology, the carbon crank arms have a patented fit interface with the axle that, along with the axle’s robustness, leads to increased power transfer when the force is applied to the left crank. This design solves a specific problem, which is that power losses are mainly generated by axle torsion under pedaling force.

The Twin Leg Technology allows riders to adjust the orientations of Rotor’s Q RINGS oval chainrings by degrees relative to the crank. OCP Mount is based on the combination of three independent elements: axle, right crank arm, and spider with the oval chainring. The patented crank interface for a DM Q RINGS allows for the most precise adjustment of an oval chainring to date.

With these new benefits built into the crank structure, riders who place a premium on choice can customize their cranksets owing to Aldhu’s modular structure. Rotor first introduced this concept into its product range in 2017. Since then Rotor has added components to the ALDHU category to further extend its customization configurations.

Aldhu’s modularity offers riders the added advantage to upgrade to the new carbon crank arms if they already use an Aldhu or VEGAST crankset. A 10 mm Allen key, a pair of ALDHU Carbon cranks, and two minutes are all it takes to complete this easy upgrade.

Riders can easily add power measurement with the INspider power meter like our test crank, which measures power, cadence, and balance, and employs two proprietary metrics, Torque 360 and Optimum Chainring Angle.
