SRAM Crankset Force 1x D2 DUB - Unicorn Grey w/Laser Foil - 172.5mm Direct Mount 40T (BB not included)A single chainring with a wide-range cassette is a wonderfully clean way to tackle so many disciplines, and we’re the 1x leaders. Gravel, TT, tri or crits: just pick the right chainring size for the discipline and go. Our lightweight and strong direct mount chainrings feature X-SYNC tooth technology to maximize chain retention, and they bolt to carbon arms with a spectacular but subtle finish.Direct mount chainrings are lighter and stiffer than traditional spider-based rings
48T and 50T variants have direct mount aero chainrings for better aerodynamics
SRAM X-SYNC wide-tooth, narrow-tooth chainring technology provides maximum chain control
DUB bottom bracket adds durability and simplicity
Can be upgraded to a power meter
Technology
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.
