Rotor noQ-Ring Chainring DM

With the Q RING DM RUND black With the modular ROTOR ALDHU, ROTOR has developed a future-oriented road bike crank system that can be freely configured and assembled without special tools or specialist knowledge. Thanks to the Direct Mount System, the exchange of reeds is a matter of minutes when using the combination chainring in one-piece design or single reeds with Direct Mount Spider. an Allen key is sufficient. Whether with round chainrings or Rotor's oval Q-rings, everything is possible and available in many variants. The Direct Mount System of the ALDHU enables for the first time the fine adjustment of oval chainrings in 1-degree steps and thus an incomparable individualization to the personal requirements. In the configuration of the ALDHU, several chainring combinations milled from a single block (one-piece design) are available and push the system weight below the magical 600 gram mark. Alternatively, the crank can also be configured with a lightweight Direct Mount Spider and two single chainrings. The One-Piecedesign chainrings are made of one piece and are mounted on the axle using the Direct Mount method without tools. To change the chainrings, only a 10mm hex key is required to mount and dismount the crank arm on the drive side. The cracking due to the screw connections between spider and chainring is now a thing of the past. The ovality of the chainrings is 12.5%.
