SRAM Force CX1 One Less Barrier to Cross The new SRAM Force CX1 groupset is a complete high-performance 1x 11 cyclocross drivetrain created by blending the best of SRAM’s revolutionary XX1 mountain bike & road technologies. This is a single-ring, 11-speed complete drivetrain that is lighter, simpler, & tougher while offering a clean look & optimal gear selection for cyclocross. SRAM Force CX1 offers better chain management & smooth shifting no matter the conditions or terrain. It is the only true 1x dedicated cyclocross system. X-SYNC™ Sram X-Sync™ 1X chain rings provide the highest level of performance & durability. The SRAM X-SYNC™ tall square teeth edges engage the chain earlier than traditional triangle shaped teeth. The sharp & narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain. To provide the best possible performance in muddy conditions, the X-SYNC™ chain rings have been designed with mud-clearing recesses for the inner chain links & rollers. Engineered in Germany, X-SYNC™ rings are an integral part of the SRAM 1X™ drivetrain.
