A single chainring with a wide-range cassette is a wonderfully clean way to tackle so many disciplines, and we're the 1x leaders. SRAM's Apex 1 Wide Crankset features aluminum crankarms, a light and stiff DUB spindle, and elegant and secure direct-mount X-Sync chainrings for flawless chain management. The wide chainline accommodates wider tyres for any type of adventure.

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.

Boost

Boost is the standard wheel and drivetrain specification that opens the opportunity 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.

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.
