RED®1 Aero Crankset 1×12

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.
