Get reliable 1x12 shifting on a budget with the SRAM SX Eagle crankset. It brings genuine Eagle chain retention and a tough steel chainring to entry-level mountain bikes, so you can ride confidently over rough ground without dropping your chain.

Highlights

  • Forged aluminium crank arms in a 170mm length
  • 32T X-SYNC 2 steel direct-mount chainring included
  • Standard (non-Boost) fit with a 49mm chainline
  • PowerSpline spindle interface for proven, serviceable bottom brackets
  • Compatible with all 11- and 12-speed SRAM Eagle drivetrains

Eagle chain retention

The 32T direct-mount chainring uses SRAM's X-SYNC 2 tooth profile, with alternating narrow and wide teeth that grip the Eagle chain tightly. This keeps the chain seated through rocks, roots and hard landings without the need for a chain guide.

Built to last

Solid forged aluminium arms and a steel chainring give the SX Eagle a durable, no-fuss character that suits everyday trail riding and hard-wearing rental or commuter builds.

Fit and compatibility

This is the standard (non-Boost) version with a 49mm chainline, suited to frames using 142mm or QR rear spacing. It runs on a PowerSpline cartridge bottom bracket (118mm/73mm, sold separately) and works with any 11- or 12-speed SRAM Eagle chain and cassette. If your frame is Boost 148 spaced, choose the Boost 52mm chainline version instead.
