WOLF TOOTH Aero chainring 107x50 BCD for SRAM

Product description

The Wolf Tooth Aero 107 BCD (50 tooth) chainring is designed for gravel and road racing and for all riders who tune every detail in the pursuit of higher speed. The chainring stands out with its high strength, low weight and specific aero profile that seamlessly connects to the cranks for a clean, integrated look. Combined with modern wide-range cassettes, this 50 tooth chainring for single-plate systems (1x) offers a comparable gear range to classic double-chainring setups.

It uses patented Drop-Stop® B profile teeth, optimized for SRAM Eagle and Flattop chains, ensuring maximum durability, reliable chain guidance and effective mud clearance.

Wolf Tooth Aero 107 BCD chainrings are designed to pair flawlessly with the SRAM AXS 107 BCD power meter spider.

Key features

• Specific 50 tooth size: Ideal choice for fast tracks, road and gravel racing applications.

• Drop-Stop® Technology: Patented wide/narrow tooth profile prevents chain drop on 1x systems. The wide side of the tooth provides maximum contact area for power transfer and extends life, while the narrow side reduces friction and leaves room for self-cleaning of mud.

• Drop-Stop B profile: Fully optimized for SRAM Eagle chains and SRAM Flattop road/gravel chains.

• Pure aero integration: The chainring shape perfectly matches the SRAM AXS 107 BCD removable power meter carrier.

Compatibility

• Cranks and carriers: Designed for SRAM 107 BCD cranks with a removable power meter carrier. Also fits standard SRAM 107 BCD removable carriers without a power meter. (If you are not using a power meter, the manufacturer recommends SRAM 8-bolt Direct Mount chainrings for a lighter and cleaner setup.)
• Drivetrains and Chains: Compatible with SRAM 12-speed and 13-speed groupsets including SRAM Red XPLR AXS.
• Front Mount: Designed exclusively for setups where the chainring is mounted on the front of the carrier (not compatible with systems requiring rear mount, such as some Specialized Creo models).
• Not compatible with SRAM Rival 107 BCD cranks with integrated/non-removable carrier (codes FC-RIV-D1 and PM-RIV-D1).
• Designed exclusively for single-plate drives (1x) - not compatible with derailleur (2x).

Recommendations for installation and operation

• data-path-to-node="8,0,0">Assembly: Use the included Wolf Tooth screws. Lightly grease the threads with Vaseline and tighten to 5 Nm using a 4mm Allen key.
• Chain protection: For maximum reliability, we recommend using a derailleur with a chainstay brake. For extreme and very muddy conditions, it is recommended to add a chain guide (e.g. Wolf Tooth LoneWolf or GnarWolf).
• Chainline: This is determined by the specific model of cranks used (follow the crank manufacturer's specifications).
