Built for fat bikes, this SRAM X-SYNC 2 Eagle direct-mount chainring sets the wide chainline those frames need while delivering SRAM's renowned chain retention. Its second-generation tooth profile keeps the chain locked on, runs quietly and wears slowly, in a 30T black finish.

Highlights

  • Improved X-SYNC 2 tooth shape for class-leading chain retention
  • Forged and machined aluminium for a strong, light single ring
  • 3-bolt direct-mount interface for fast, secure fitting and easy swaps
  • Tuned for SRAM Eagle 11- and 12-speed 1x drivetrains
  • -4mm offset to suit wide fat-bike rear hub spacing

Why X-SYNC 2

SRAM redesigned every tooth with a longer, positive-rake shape that meshes precisely with the Eagle chain. The result is better chain retention over bumps, smoother pedalling and reduced friction, noise and wear, so power transfer stays crisp ride after ride.

Built to last

This ring is cold-forged and machined from aluminium for a strong yet lightweight single-ring setup. The 3-bolt direct-mount design fixes the ring straight to the spider-less crank arm for excellent stiffness and tool-light ring changes.

Compatibility and fit

This 30T ring has a -4mm offset, designed for the wide chainline of fat-bike cranks (typically 190mm rear hub spacing). Use it with SRAM 3-bolt direct-mount fat-bike cranks running an Eagle 11- or 12-speed 1x drivetrain. For standard non-Boost bikes choose the 6mm offset version, or the 3mm offset for Boost 148mm. If unsure which offset suits your bike, contact our team before ordering.

SRAM warrants this chainring to be free from defects in materials and workmanship in line with SRAM's standard component warranty (two years from the original date of purchase). The warranty covers manufacturing defects only and does not cover damage from crashes, improper installation, normal wear, or modification.

For any warranty claim or support, please return the item to Tune Cycles and our team will manage the process for you.
