Part of Rotor's new innovative modular ALDHU 3D+ system, the ALDHU Road Axle connects the crank arms and is compatible with a range of bottom bracket standards. Weighing a mere 96 grams, together with the ALDHU spider, chainrings and crank arms, this is the lightest Rotor crankset available. This is a standard version with a Q-factor of 147mm, making it suitable for rim brake road bikes.
