   DUB Technology–        The relationship between bottom bracket spindle and bearing is the core of DUB technology. It’s where stiffness meets durability. SRAM took it a step beyond conventional thinking and made everything simpler—better integrating the relationship between chainring, crank, spindle and bottom bracket. It’s this approach to developing a complete system that equals better drivetrain performance.

   BOOST–        BOOST specification opens up the opportunity for improved frame geometry with shorter chainstays, wider and stiffer suspension pivots, a wider range of chainring options, and bigger, wider tires.

   X-SYNC™–        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. 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™ chain rings 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.
