New SRAM RED AXS: the lightest electronic groupset in history is also smoother and more precise

The new SRAM RED AXS has just been released. It is the most advanced and lightweight electronic road groupset of the moment and among its key features are the comfortable ergonomics and light touch of the brakes, the smooth and precise shifting, the reliable wireless connectivity, and the wide gear range. In its lightest version with a power meter, the complete SRAM RED AXS weighs 2,496 g.

The new SRAM ?RED AXS is completely updated to be lighter, more precise, and smoother than ever

The new RED AXS has updated each and every one of its components to reduce the total weight while improving its performance and functionality. As we mentioned in the title, SRAM claims to have manufactured the lightest electronic road groupset in history and has also achieved more precise and reliable power measurement, better shifting capability, and greater brake adjustment range. But let's look at each component separately.

SRAM RED AXS HRD Brake and Shift Levers

The SRAM RED AXS brake and shift levers have been developed to be used with a single finger effortlessly. This has been achieved with a new lever structure that improves its fit and ergonomics for all hand sizes. Additionally, this design allows for more powerful and smoother braking from any point on the handlebar.
