SRAM pioneered the 1x drivetrain and the Force 1 crankset is the innovative evolution. It's lighter, stronger and simpler - non-aero chainrings can now be mounted with a single tool. This is the 1x crowning achievement for cross, TT, triathlon and criterium. X-SYNCX-SYNC 1x chainrings from SRAM ensure maximum performance and durability. SRAM's long X-SYNC tooth edges grip the chain earlier than traditional triangular shaped teeth. The sharp and narrow tooth profile as well as the rounded slanted edges support the chain guide. To offer the best possible performance even in muddy terrain, the X-SYNC chainrings have recesses for the inner chain links and rollers to remove dirt and mud. The German-made X-SYNC chainrings are an important component of SRAM's 1x drivetrain. DUB technologyThe crankshaft and bottom bracket unit is the heart of DUB technology. This is where stiffness meets durability. SRAM have gone a step further and made everything even simpler and better. It is the system approach through the integration of chainring, crank, shaft and bottom bracket that means better drivetrain performance. X-RangeRoad bikes are faster and more powerful than ever before, and riders are expanding the possibilities possible with dropbar bikes. X-Range is the gearing for road cycling today. SRAM has completely redesigned road bike shifting to provide a wider range, more useful and smoother gear gradation, and smarter shift settings made possible by AXS. With X-Range, you always have the right gear engaged.
