SRAM Force AXS D1 Crank Set 40 Teeth Without Bottom Bracket Dub black

Sram pioneered the 1x drivetrain, and the Sram Force 1 crankset evolves the innovation. It's lighter, stronger and simpler—non-aero chainrings can now be installed with a single tool. For cross, TT, tri and crits, this is the king of 1x.

X-Range
Racing bikes are faster and more powerful than ever before and riders keep showing what bikes with racing handlebars are capable of. X-Range offers a wider range of gear ratios, as well as an even more pleasant and usable gear gradation... and also has smart, programmable shift settings thanks to AXS.

X-Sync
X-SYNC 1x chainrings from Sram ensure highest performance and durability. The long Sram X-SYNC tooth edges grip the chain earlier than traditional triangular teeth. The sharp and narrow tooth profile as well as the rounded inclined edges support the chain guide. To provide the best possible performance even on muddy terrain, the X-SYNC chainrings have recesses for removing dirt and mud from the inner chain links and rollers. The X-SYNC chainrings manufactured in Germany are an important component of the 1x drive from Sram.

DUB 
The new SRAM DUB bottom bracket series has a simple job—connect your crankarms and protect the smooth, long-lasting application of power to your drivetrain. To allow that singular focus, SRAM engineered the DUB spindle to be the one true unifying component. One oversized spindle to work across every bottom bracket standard. For better crankarm compatibility. For better protection from the elements. For longer-lasting performance. To be stronger, smoother, simpler. Now, back to the ride.
