R ROTOR BIKE COMPONENTS Q RINGS DM OVAL CHAINRING 50/34 T BLACK

With the modular ROTOR ALDHU ROTOR has developed a forward-looking road bike crank system that can be freely configured and mounted without special tools and expertise. Reeds can be swapped in minutes with the Direct Mount system when using the combination chain blade in a one-piece design or with single blades with Direct Mount Spider. An Allen key is enough. Whether with round chain rings or the oval Q rings from Rotor, everything is possible and available in many variants. The direct mount system of the ALDHU allows for the first time the fine adjustment of oval chain rings in 1-degree increments and thus an incomparable individualisation to the personal requirements. When configuring, the ALDHU has several one-piece design milled chainring combinations available and press the system weight under the magic 600 gram mark. Alternatively, the crank can also be configured with a light Direct Mount Spider and two individual chain blades. The chain rings in one-piece design are made from one piece and are mounted on the axle without tools in the direct mount process. To change the chain rings, only a 10-hex key is required to assemble/dismantle the crank arm of the drive side. The cracking due to the screw connections between spider and chain ring is a thing of the past. The oval of the chain rings is 12.5 %.
