The Magene ROTOR ALDHU Road Power Meter Crankset combines the Magene P505 spider-based power meter with ROTOR ALDHU crank arms. This is an affordable, high-quality power meter crankset that features dual leg power measurement, +/- 1.0% accuracy and a rechargeable battery with 200 hours of ride time.

We are happy to professionally assemble your power meter crankset if you select this option when ordering. This ensures your crankset is correctly built and saves you time. Professional assembly includes:
Mount the power meter to the cranks and tighten to factory specifications Apply multi-purpose bicycle grease where necessary Install chainrings on the power meter (if chainrings are ordered)
Please note – while we tighten everything to factory specs, it is still your responsibility to routinely check your power meter crankset to make sure all bolts and nuts remain securely fastened. Compatibility Chainrings:
This power meter fits both 110x4 BCD and 110x5 BCD chainrings. In many cases, you can use your existing chainrings assuming they use the same configuration as the power meter you order.
The 110 BCD 4-Bolt version is compatible with all Shimano 4-bolt chainrings, including Shimano 12-speed chainrings. What is BCD?:
BCD (bolt circle diameter) is simply the diameter of a circle that passes through the centers of the bolt holes in your chainring. The BCD is usually stamped right on the chainring as either 110 or 130. It is important to know what BCD your crankset is because assuming you want to use your existing chainrings on your new power meter, you need to order the correct BCD. Bottom Bracket:
This power meter fits 24 mm or 30 mm bottom brackets, depending on the version ordered. If you are ordering the same size as you currently have on your bike, you should be able to re-use your existing bottom bracket. However, if you are changing spindle sizes, you will need to replace your bottom bracket. Please contact us with questions, we are happy to help.
