The SRAM Force 1x AXS D2 DUB Direct Mount 12-Speed Crankset is engineered for cyclists who demand simplicity, efficiency, and versatility across various disciplines, including gravel, time trial, triathlon, and criterium racing. Embracing a 1x drivetrain setup, this crankset offers a clean, lightweight solution without compromising performance.

Crafted with carbon crank arms, the Force 1x crankset ensures exceptional stiffness-to-weight ratio, providing responsive power transfer and durability. The direct mount chainrings are both lighter and stiffer than traditional spider-based rings, enhancing overall drivetrain performance. Available in a range of sizes—38T, 40T, 42T, 44T, and 46T—you can select the optimal chainring to match your specific riding style and terrain.

For riders seeking greater tire clearance, the Wide variant of this crankset features a longer DUB spindle, accommodating both road and mountain bike bottom bracket standards. This design allows for the installation of wider gravel tires, making it compatible with 135mm, 142mm, and Boost rear spacing.

The integration of SRAM’s X-SYNC™ technology ensures maximum chain control. The tall, square teeth of the chainring engage the chain earlier than traditional designs, providing consistent performance even in muddy or adverse conditions. Additionally, the DUB (Durable Unified Bottom Bracket) system simplifies the relationship between the spindle and bottom bracket, enhancing durability and simplifying maintenance.

Designed with future upgrades in mind, this crankset can be seamlessly integrated with a power meter, allowing you to monitor and optimize your performance metrics as needed.

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.
