Time trial, triathlon or stage races in flat terrain. Some kinds of bicycle racing sports are predestined for the use of an uncomplicated singlespeed drivetrain. The RED®1 Aero 12-speed crankset by SRAM is just the right tool for you to show maximum performance. As an important component of SRAM’s X-Range™ technology, it helps shift the gear range from the front to the rear. DirectMount Aero chainrings make for improved aerodynamics and the elimination of a front derailleur and a second chainring reduces the weight while increasing the functionality for a particularly intuitive drivetrain. After all, a wide range of gears makes less sense in time trial - whereas efficient gear and cadence control prove advantageous.

Specifically developed for electronic shifting, SRAM’s RED®1 Aero crankset impresses not only with elegant Exogram™ carbon crank arms, but also with the possibility to upgrade it with a powerful power meter whenever you want.

Road bikes and road cyclists are faster and more capable than ever. The X-Range™ technology offers a wider and better range of gears. Thus it provides smoother, more useful gear progression. Smart shift settings (enabled by AXS™) transfer the simplicity of singlespeed systems to double speed drivetrains. Thus, you’ll always find the right gear. Faster – more efficient – more comfortable!


The relationship between 28.99 mm diameter spindle and bottom bracket is the core of the DUB™ technology. This is where stiffness meets durability. Thanks to the system approach of integrating the relationship between chainring, crank, spindle and bottom bracket, SRAM has managed to make everything easier and better. It’s particularly the bottom brackets that benefit from increased durability thanks to an improved protection against dirt, resulting in enhanced drivetrain performance.


SRAM X-SYNC™ 1x chainrings provide the highest level of performance and durability. The tall square teeth edges engage the chain earlier than traditional triangle shaped teeth. The sharp and narrow tooth profile and rounded chamfered edges help guide the chain. In addition, X-SYNC™ chainrings feature mud-clearing recesses for the inner chain links and rollers to provide the best possible performance in muddy conditions.
