SRAM Force 1X D1 AXS Dub Wide Crankset

We originated the 1x drivetrain, and the SRAM Force 1 Wide crankset evolves the innovation. It’s lighter, stronger
and simpler and are direct mount for less weight. Wide variant cranks accommodate the largest of tires for your 1x
gravel machine.

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.

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-Range

Road bikes are faster and more capable than ever before, and riders are expanding what’s possible with drop bar
bikes. X-Range is gearing for today’s road riding. We completely reimagined road gearing for wider range, more
useful and smoother gear progression, as well as smarter shift settings—enabled by AXS. With X-Range, you’re always
in the right gear.
