ROTOR 110×4 Oval Aero Chainrings for Shimano
The all-new ROTOR 110×4 Oval Aero Chainrings for Shimano give you the benefits of stiff chainrings in a neat, clean-shifting, aerodynamic package. The oval shape works to smooth your pedal stroke and increase both traction and power. These chainrings are finished with a gloss black powder coat and are machine CNC’d from aeronautic-grade 7055 aluminum.
These chainrings are compatible with 110×4 road cranksets and have been updated to be fit Shimano 12-speed 7100, 8100 and 9200 cranks. They also fit ROTOR modular cranks and power meters when used with the ROTOR 110×4 Spider. This spider also allows these chainrings to use ROTOR’s OPC technology to optimize your pedal stroke. For peak aerodynamics, we recommend using these rings with the ROTOR Aero Crown.
Important Notes:
1. ROTOR Road Chainring Bolts are required for use with Shimano cranksets.
2. The ROTOR 110×4 Spider is required for use with the ROTOR 2INpower and INpower DM power meter or the ALDHU and VEGAST crankset. It is not required for use with Shimano and other 110×4 cranksets.
