ROTOR INspider ALDHU Carbon 2x Road Power Meter Crankset
The ROTOR INspider ALDHU Carbon 2x Road Power Meter Crankset features ROTOR’s spider-based power meter paired with it’s first every carbon crankset! The INspider measures power from both legs, recording data via four sets of opposing gauges. This results in a high degree of accuracy (+/- 1.5%) and also means the power meter can measure left and right leg power balance. In addition, the ALDHU Carbon Crankset is crazy light, weighing only 260 grams. In addition, vertical and horizontal stiffness had been increased by 11% and 36%, respectively.

Other Versions to Consider
Aluminum Version: We also have the ROTOR INspider ALDHU Road Power Meter Crankset which features ROTOR aluminum crank arms. This version is more affordable, but the aluminum crank arms are not quite as nice. An advantage to the aluminum version however is they come in both 24 mm and 30 mm spindle sizes.
Chainrings: The INspider ALDHU Carbon is compatible with a wide selection of ROTOR chainrings. They are designed to work with 9-, 10-, 11-, 12-, and 13-speed groupsets.
Bottom Bracket: This power meter uses a 30 mm spindle and must be used with a 30 mm bottom bracket.
Note - The INspider does not fit Trek bikes that have a T47 bottom bracket.

Common Questions and Answers
Question: Does the ROTOR INspider ALDHU Carbon 2x Road Power Meter Crankset come in a 24 mm version?
- Unfortunately, no. ROTOR only makes the ALDHU Carbon in 30 mm. However, the ROTOR INspider ALDHU 2x Road Power Meter Crankset comes in both 24 mm and 30 mm.
Question: How do I determine what length my current cranks are so I can make sure I get the same size?
- Your crank arm length should be printed or stamped on the inside of the left crank arm, usually near the pedal end.
