ROTOR Round Rings BCD110x4 SRAM® AXS Drivetrain compatible . ROTOR has poured all of its experience in oval Q RINGS development into producing an innovative Round Chainrings solution compatible with SRAM® eTap AXS 12s groupsets and all ROTOR cranks using spider BCD 110x4 or INspider powermeter.
When used with the INspider, these rings are best paired with the aero crown.
NOTE: Chainrings must have a 13 tooth gap for AXS compliance. This means 48/35t or 50/37t.
Some frames may run into AXS derailleur clearance issues with the larger diameter 50t outer ring.
If currently running a 48t ring, ensure there is room to raise the front derailleur.
