The Wolf Tooth Direct Mount Chainring for SRAM 3 bolt cranks is a 32 tooth single ring with 3 mm offset, which gives a 52 mm chainline for Boost frames.

What it's for

This ring bolts straight to the back of a SRAM 3 bolt direct mount crank arm, with no spider. Use it to replace a worn ring, change tooth count, or correct chainline.

How it works

Drop-Stop tooth profile: The teeth alternate wide and narrow to match the wide and narrow gaps in a chain. That keeps the chain centered on the ring. Wolf Tooth says the wide teeth spread the load for longer wear and the narrow teeth leave room for mud to clear.

Offset sets chainline: Offset is how far the teeth sit inboard of the mounting face. Wolf Tooth lists 6 mm offset as a 49 mm chainline, 3 mm offset as 52 mm (Boost or Super Boost), and 0 mm offset as 55 mm (Boost short spindle, and what SRAM Transmission is built around).

Compatibility

  • Cranks: SRAM 3 bolt direct mount cranksets, including DUB, and Cane Creek eeWings
  • Does not fit: SRAM 8 bolt direct mount cranksets
  • Chain: depends on the tooth profile marked on the ring. See the three profiles below.
  • Drop-Stop A: all 9, 10, and 11 speed chains, plus 12 speed SRAM Eagle, Connex, and Wippermann. Not for Shimano HG+ 12 speed, KMC 12 speed, SRAM Transmission flattop, or Campagnolo 12 speed.
  • Drop-Stop B: all 9, 10, and 11 speed chains, plus 12 speed SRAM Eagle, SRAM flattop (road and Transmission), Connex, Wippermann, and Campagnolo. Not for Shimano HG+ 12 speed, KMC 12 speed, or Campagnolo 13 speed.
  • Drop-Stop ST: Shimano HG+ 12 speed and KMC 12 speed chains only.
  • How to check yours: Pull the crank and count the bolts on the back of the drive side arm. Three T25 bolts means 3 bolt direct mount. Then confirm your frame calls for a 52 mm chainline.

Setup and installation

  • Bolts: reuse the 3 existing bolts from the back of your crank
  • Tool: T25. Wolf Tooth notes a T25 L wrench works well.
  • Torque: follow SRAM's spec for your crank. Wolf Tooth does not list one.
