SRAM 107 BCD AERO DROP-STOP B CHAINRING

Designed for gravel and road racing, and for those looking to optimize each detail in pursuit of speed, Wolf Tooth Aero Chainrings are strong, lightweight, and profiled to mate perfectly with your crankset for a clean, integrated look. Taking advantage of 1x drivetrain systems and wider-range rear cassettes, Aero Chainrings are available in sizes 46T to 50T to provide similar overall range to standard 2x drivetrain configurations. They feature our patented Drop-Stop® design for the best wear life, chain retention, and mud clearance. Drop-Stop B is optimized for SRAM Eagle and Flattop chains.

Wolf Tooth Aero 107 BCD Chainrings for SRAM Cranks are designed to pair seamlessly with the SRAM AXS 107 BCD Power Meter Spider.

• Fits SRAM AXS 107 BCD cranks with a removable power meter spider and SRAM 107 BCD cranks with removable spiders. NOTE: THIS DOES NOT FIT SRAM APEX CRANKS
• Drop-Stop technology: On Wolf Tooth’s patented wide/narrow chainring, the wide side of the tooth has maximum contact on the drive side which spreads the load and improves chainring life. The narrow side allows clearance for mud and debris which reduces friction.
• Alternating wide/narrow tooth pattern prevents chain derailment.
• Cranks that use the 107 BCD spider also use the SRAM 8-bolt interface, which is compatible with Wolf Tooth Direct Mount Chainrings for SRAM 8-Bolt

COMPATIBILITY

• Designed for SRAM 107 BCD cranksets with removable power meter spiders. Also fits standard SRAM 107 BCD removable spiders without power meters.
• Not compatible with SRAM Rival 107 BCD cranksets with integrated (non-removable) spiders. (models ID's FC-RIV-D1 and PM-RIV-D1)
• Chainline is determined by the crank model. See manufacturer specs for chainline.
• Chainrings are designed for 1x drivetrains. They are not compatible with 2x drivetrains.
• Use Drop-Stop B for all 9, 10, and 11spd chains or 12spd KMC, Connex, Wippermann, Campagnolo, SRAM Eagle, SRAM Road and Transmission (T-type) Flattop chains

DROP-STOP TECHNOLOGY

Wolf Tooth’s patented Drop-Stop® wide/narrow tooth profile delivers ultimate chain retention and mud shedding ability.

RECOMMENDATIONS

• If you plan to ride in very muddy conditions, we recommend a chainguide or chainkeeper in addition to a clutch-type rear derailleur. Without these precautions, you may experience chaindrops and/or chainsuck.
• We recommend the use of a clutch style rear derailleur for the best chain security.
• For Installation, use the included Wolf Tooth chainring bolts. Apply light grease to threads and torque to 5Nm with a 4mm hex bit.
