R ROTOR BIKE COMPONENTS DM ROUND RING 46/30 BLACK

Q Ring 46/30 DM round black with the modular rotor aldhu has developed a forward-looking racing wheel crank system that can be freely configured and mounted without special tools and expertise. The exchange of leaves is a matter of minutes thanks to the Direct Mount system when using the combination chain blade in a one-piece design or with simple blades with Direct Mount Spider. One 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 The aldhu allows for the first time the fine adjustment oval chain rings in 1 degree increments and thus an incomparable individualisation to the personal requirements. In the configuration of the aldhu are several one-piece design milled from a block and chain blade combinations available and press the system weight under the magic 600 gram brand. 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. Cracking due to the screw connections between spider and chain ring is a thing of the past. The rivalry of the chain rings is 12.5 %.
