X01 chainrings  have precisely machined alternating tooth profiles to perfectly match the chain's inner and outer link width. The chainring engages the chain like a vice virtually eliminating the need for a chain guide. Sram calls it X-Sync technology, we call it life-changing. When combined with the Sram X01 rear derailleur with roller bearing clutch, the chain is as secure without a guide as a bike without gears at all.

  • SRAM X-SYNC™ 1X chain rings provide the highest level of performance and durability. The SRAM X-SYNC™ tall square teeth edges engage the chain earlier than traditional triangle shaped teeth.

    Replacement chain rings in 94mm and 104 mm BCD for X01 cranks. Replace a worn out ring or swap to change gearing; crank removal not required
