Escapa presents theRotor Q-Rings AXS BCD107x4 50T (For 37) 12S Outer Chainring, an oval BCD107x4 outer chainring for SRAM AXS 11/12-speed systems. It optimizes pedaling with 12.5% ovality, improves efficiency, and reduces fatigue. Lightweight CNC-machined aluminum for precise shifting.
Features:
Shape: Oval (Q-Rings), with 12.5% ovality designed to optimize pedaling efficiency by varying the effective diameter of the chainring during rotation, minimizing dead spots.
BCD (Bolt Circle Diameter): 107 mm, with an asymmetric 4-bolt pattern, specifically for SRAM AXS cranksets.
Compatibility: Designed as an outer chainring for double-chainring setups with SRAM Red eTap AXS BCD107x4 cranksets, SRAM Force eTap AXS BCD107x4 cranksets, and SRAM AXS Power Meter BCD107x4 cranksets. Specifically for use with a 37-tooth inner chainring.
Number of Teeth: 50T (optimized for use with a 37T inner chainring).
Speed: Compatible with 11- and 12-speed SRAM AXS drivetrains.
Material: CNC-machined 7075-T6 aluminum alloy, offering a balance between lightness and durability.
Pedaling Optimization: The oval shape is designed for smoother, more efficient power delivery throughout the pedal stroke, improving traction and reducing fatigue.
Shift Ramps and Pins: Features shift ramps and pins designed to ensure precise and fast shifting between chainrings.
Chainline: 43.5 mm (for standard axle), 46 mm (for offset axle).
Weight: Approximately 144 grams per pair (50/37T combination).
Finish: Anodized for greater resistance to wear and corrosion.
