The Apex 1 crankset completes the Apex 1 group, SRAM's most affordable road 1x drivetrain yet. Using patented X-Sync technology, the Apex 1 crankset runs silent and secure. Riders looking for a wide gear range and shifting simplicity at a great value will find it in Apex 1.
Technology
X-Sync
SRAM X-Sync 1x chainrings 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. The sharp and 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 chainrings have been designed with mud-clearing recesses for the inner chain links and rollers. Engineered in Germany, X-Sync rings are an integral part of the SRAM 1x drivetrain. Accept no imitation.
