Rotor QRings AXS 37D BCD 107x4 Inner Chainring Black

The Rotor QRings AXS 37D BCD 107x4 inner chainring is a chainring that Rotor staff noticed when SRAM changed standard chainring sizes with their RED eTap AXS 12-speed groupset, Rotor quickly pivoted to the concept and created compatible oval chainrings. Combinations of 50/37 and 48/35 QRings with BCD 110x4 or BCD 107x4 are new standards for SRAM loyalists who want to improve their performance and pedal in a healthy way.Features:- Use: Road - Model: QRings AXS - Teeth: 37D (only compatible with 50D) - BCD: 107x4 - Material: Aluminium - Compatible cranks: All ROTOR cranks with BCD 107x4 spider.
