Rotor ALDHU Direct Mount Round Chainrings

Rotor's innovative ALDHU 3D+ technology features a modular structure so individual components can be replaced for a customised set up suited to each individual riders needs. Mounted directly onto the crank arm, the ALDHU Direct Mount Round Chainrings create a rigid structure subject to less stress and friction thanks to the need for fewer bolts. Simple, and around 30 grams lighter than a standard chainring combination, yet still highly durable.

The patented anchoring system of Optimal Chainring Position (OCP) Mount technology ensures a robust, smooth engagement between the direct mount and the axle for efficient power transfer. The tooth design benefits from all Rotor's technological experience in developing oval Q-Rings and shifting is fast and accurate, regardless of the conditions.

With all components available individually, set up is easy, and all you will need is one 10mm Allen key, so there should be no need to replace the whole unit if parts get worn. A laser etched black anodised finish offers a subtle design that will complement all bike setups.
