Equipped with SRAM'S X-SYNC™ technology, which engages with the chain much quicker than standard chainrings & provides reliable chain retention over all terrains & in all conditions. SRAM 1x™ has been made even better with the simplicity of the new SRAM X-SYNC™ Direct Mount chainring. Engineered in Germany, the new Direct Mount rings bring lighter weight & greater simplicity to XX1, X01 & X1-1400 cranksets. SRAM’s Direct Mount rings give riders the perfect opportunity for a serious upgrade. Technologies: X-SYNC™: SRAM 1X chainrings provide the highest level of performance & durability. Their tall square teeth edges engage the chain earlier than traditional triangle shaped teeth & their sharp & narrow tooth profile, as well as their rounded chamfer edges, help manage a deflected chain. To provide the best possible performance in muddy conditions, the X-Sync™ chainrings 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. Boost™: With revolutionary advancements in bicycle componentry, like SRAM’s XX1, X01 & X1 drivetrains, mountain bike designers have been given almost limitless freedom to focus solely on the performance of the bike. Each advancement demands that the entire package works flawlessly. Aggressive Trail & Enduro riders have been increasingly enjoying the benefits of larger wheels, but many still view 27.5" & 29" wheels as a possible weak link. This is why SRAM has developed an open standard with Boost™ compatible components for SRAM drivetrain, hubs & Rock Shox forks.
