Very light, high quality CNC milled 1x Narrow-Wide Aero chainring for 110x4 hole circle. Aero-cover is not included.
The ROTOR 110x4 Aero chainrings form a closed surface with the ROTOR INspider (+ Aero cover) or ROTOR MAS 110x4 Spider, so that the air flow does not break off and thus offers an aerodynamic advantage.
Can be combined with ROTOR Direct Mount System:
Note: The Aero cover is not included in the scope of delivery and must be ordered separately. Product No.: ROT449147
At the point of greatest force output, Q rings have the largest diameter. At the upper and lower dead center the smallest diameter is located, so that e.g. at the mountain the dead center is overcome more easily and this makes a smoother step under load possible.
Using the OCP Direct Mount System, the oval chainrings of ROTOR Direct Mount cranks can be adjusted in up to 20 different OCP positions and thus optimally adapted to the individual pedal position. The ovality of the chainrings is 12.5%.
In exceptional cases, the use of Q rings may cause problems in finding the optimal alignment of the front derailleur bleach.
The new ROTOR Q RING wedge adapter is mounted between the clamp and the front derailleur for better alignment. (ROCKPQADAPTER)
The chainrings can also be mounted on Shimano© 4 arm cranks in the OCP3 position used by most riders.
For Shimano cranks the matching covers for a flush transition to the crank are recommended:
