SRAM 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.
MODEL ID: FC-FRC-1W-D1
- Direct mount chainrings in 38t through 46t
- DUB™ bottom bracket adds durability and simplicity
- Wide chainline crankset to fit the biggest gravel tires
- Longer DUB crank spindle accommodates both Road and MTB width frame bottom bracket standards for unmatched cross-compatibility across brands
- Compatible with 135, 142 and Boost rear spacing
- Can be upgraded to a power meter
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.
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.
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. SRAM 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.
