DUB Technology
The combination of crankshaft and bottom bracket is the heart of DUB technology. Here, stiffness meets durability. SRAM has taken a step further, making everything simpler and better. It is primarily the system approach through the integration of chainring, crank, spindle, and bottom bracket that leads to improved drivetrain performance.

X-SYNC
SRAM's X-SYNC 1x chainrings ensure maximum performance and durability. The long SRAM X-SYNC tooth edges engage the chain earlier than traditional triangular teeth. The sharp and narrow tooth profile, along with the rounded angled edges, support chain retention. To provide the best possible performance even in muddy terrain, the X-SYNC chainrings feature recesses for the removal of dirt and mud from the inner chain links and rollers. The X-SYNC chainrings, manufactured in Germany, are a crucial component of SRAM's 1x drivetrain.
