SRAM Force 1 Crankset, 40T, 1x12-speed

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.

X-Range

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

DUB™

The unit consisting of crankshaft and bottom bracket is the core of the DUB technology. Here stiffness meets durability. Sram is has gone a bit further and made everything even simpler and I've done my job better. It is decisively the system approach through the integration of chainring, crank, shaft and bottom bracket, which means better drive performance.

X-SYNC™

SRAM X-SYNC™ chain rings 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™ chain rings 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.
