No matter how hard you push in your XC or Enduro race, the SRAM X01 11-Speed Chainring with X-Sync technology helps maximize chain control, so you can stay focused on the finish line. Each tooth's thickness is precisely CNC-machined to support the chain's inner and outer links perfectly, for flawless shifting and better chain retention. The 30T chainring lets you tune your gear range, so you can match your terrain, wheel size and riding style.
X-Sync Technology features a "wide tooth, narrow tooth" pattern that is repeated around the entire X01 chainring, perfectly mirroring the 1x11 X01-specific chain's inner and outer links for maximum control
5mm thickness provides strength and stability when demands are high
