Wolftooth Aero Drop-Stop B Chainring for SRAM BCD 107 1x 12-speed

The Wolftooth AERO SRAM BCD 107 chainring is a 1x single chainring for SRAM cranksets with a removable spider. It’s right for you if you ride with a 12-speed SRAM Eagle or Flattop chain and want a lightweight aluminum chainring.

• Stays engaged with the chain on rough terrain thanks to alternating wide and narrow teeth
• Lightweight: 121 g with 46 teeth, 132 g with 48 teeth, 143 g with 50 teeth
• CNC-machined 7075-T6 aluminum for a strong, precise chainring
• Mounts on SRAM 107 BCD cranksets with a removable spider, including those with a removable AXS power meter
• Choose 46, 48, or 50 teeth: more teeth for higher gearing. 1x drivetrains only
