TECHNOLOGIES

DUB - The relationship between bottom bracket spindle and bearing is the core of DUB technology. It's where stiffness meets durability. We 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.

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 posible performance in muddy conditions, the X-SYNC chainrings have been designed with mud-clearing receses for the inner chain links and rollers. Engineered in Germany, X-SYNC rinsg are an integral part of the SRAM 1x drivetrain. Accept no imitation.

BOOST - BOOST is the standard wheel and drivertrain specification that opens the oppurtunity for improved frame geometry with shorter chain stays, wider and stiffer suspension pivots, wider range of chainring options, as well as more clearance for bigger tires and wider, stiffer wheels.
