If you have a Shimano GRX crank but are ok changing your BB to save weight and but still want use your existing GRX chainrings, both 1x and 2x, then this is the option for you.
LIGHTER AND STIFFER
Our goal was to reduce some of the weight increase, but without sacrificing the stiffness of our cranks.
The result? Crank arms that are 100 grams lighter than the ALDHU® aluminum model. At the same time, we managed to increase its absolute vertical and horizontal stiffness by 11% and 36.1% respectively.
Take control of your crankset with total modularity at a minimum weight with ROTOR's new ALDHU cranks. These streamlined cranks combine an innovative modular structure with top-tier 7075-aeronautic grade aluminum 30mm spindle, allowing you to adjust your axles and chainrings to individually customize your ride based on your needs, and your bike's standards.
Introducing our new GRX replacement gravel powermeter:
- GRX Spacing/chainline
- 5mm wider Q factor than road/ our other gravel powermeters
- Ability to run either Shimano GRX 1x or 2x chainrings
