NG ROTOR ALDHU 24mm for GRX Gravel Package
This is your direct Shimano replacement option. If you have a Shimano GRX crank this fits directly in your existing BB and uses your existing chainrings, both 1x and 2x.
The NG Rotor ALDHU R power meter set Road is our recommendation for bikes with a Shimano bottom bracket. The set consist of the NG power meter and the Rotor ALDHU R crankset with 24mm steel axle. This is a direct replacement for your Shimano GRX crankset with a 24mm spindle that fits all compatible Shimano BB's as well as fitting either (and both) your Shimano GRX 1x and 2x chainrings.
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
The aluminum crankset is forged and hollow-bored and weighs only 542g. Its 24mm steel axle allows it to replace all current Shimano-cranksets without using any special tools. Due to customer demand the set was developed for the Shimano Hollowtech II bottom bracket standard and combines superior stiffness with an excellent price-performance ratio.
