NGeco ROTOR ALDHU R 24mm

This is your direct Shimano Replacement option. If you have a Shimano crank this fits directly in your existing BB and if you want you can reuse your Shimano chainrings by selecting the Shimano 4-bolt pattern option under the BCD drop-down.

The NGeco Rotor Aldhu R power meter set road is our recommendation for bikes with a Shimano bottom bracket. The set consists of the NGeco power meter and the Rotor Aldhu R crankset with 24mm steel axle. It is compatible with the Shimano Hollowtech II bottom bracket standard. With the 110 4-S and 110 4-SL versions of the power meter, there is the option of continuing to use existing Shimano road chainrings to maintain shifting comfort. The 110 4-SL version also saves 30g compared to the regular 110 4-S version. 

Advantages over the Rotor Power2Max edition crank:

• Aldhu R 24 uses a higher grade aluminum to create a stiffer crank
• Aldhu R 24 uses further machining to reduce the weight by ~40 grams
• Aldhu R 24 has a more premium finish
