Compact Road Gearing with Modular Direct-Mount Performance

Overview

he Rotor Aldhu24 Direct Mount R50/34 Crankarm combines compact road gearing with a stiff modular crankset. It is suited to climbing, endurance riding and performance-focused road cycling.

Strong Aluminium Crankarms: The Aldhu24 crankarms are precision-machined from high-strength aluminium for a dependable balance of stiffness, durability and low weight. Their rigid construction supports efficient power transfer under load.

One-Piece Direct Mount Rings: The 50/34T round chainrings are machined from a single piece of 7075 aluminium. This direct-mount construction improves stiffness, reduces unnecessary hardware and supports smooth front shifting.
