Product ID: ROC01039XXXXXX

Improve your performances on the bike with Rotor's new ALDHU modular technology, allowing you to select individual components to optimise your crankset for your requirements.

The ALDHU Direct Mount Q Chainrings feature OCP (Optimum Chainring Position) Mount technology so you can adjust the chainrings to your pedalling biomechanics in one-degree increments to achieve the optimal position for power transfer. Constructed from CNC'd 7075 aluminium and weighing just 178 grams (52/36) the complete system is Rotor's lightest yet.

Rotor ALDHU Direct Mount Q Chainrings

Conceived to offer extra flexibility when it comes to choosing your crankset, Rotor's new ALDHU 3D+ modular system is their lightest available and the ALDHU Direct Mount Q Chainrings weigh a mere 178 grams. With the name being an abbreviation of Alpe d'Huez, this technology was named to commemorate Rotor's first iconic victory in the Tour de France.

OCP Mount technology allows one-degree adjustments to chainring position and by utilising your OCP (Optimal Chainring Position) you can reduce stress on the knees while improving your pedalling efficiency for enhanced performance. 12.5% ovality ensures you activate all muscle groups fully for increased power output.

CNC'd from 7075 aluminium and with an integrated configuration, there are fewer individual parts which in turn results in reduced weight with no compromise on durability.

Compatible with most bikes and standards, the modular system means that when parts start to wear out there is no need to replace the whole unit. Assembly is simple, requiring only one 10mm allen key, and the laser-etched black anodised finish will look great on any bike.
