The Lightest Electronic Drivetrain
On a top tier bike, every gram matters. Weight savings is a consistent theme in SRAM product development for professional racers and everyday riders. SRAM reduced weight everywhere possible over previous generation RED eTap AXS so that SRAM RED AXS is effortlessly lightweight, representing the lightest electronic groupset yet.
When you add up all the reductions, RED AXS comes in at 2,496 grams, which is 153 grams less than previous gen RED eTap AXS. That’s more than a bag of gummy bears. 

In addition to adding comfort and power to the RED AXS brakes, SRAM shaved 83 grams between the lever and caliper. When climbing on the hoods, swinging the bike side to side, it’s a weight reduction you can feel.

Crank and Chainrings
The drivetrain product development team refined the carbon layup process of the crank arms, with a little help from the carbon experts at Zipp, resulting in a 29-gram weight savings for the crank set with no loss of stiffness. Additionally, the RED chain has been updated with HollowPin construction. This technology is lighter and stronger than a solid pin, and cutouts in the outer plates drop the chain’s weight by 13 grams.

Rear and Front Derailleurs
The rear derailleur received a larger pulley wheel and ceramic bearings and has shed 16 grams overall. The front derailleur is not only faster and more precise, it’s 4 grams lighter.

The Paceline X rotors combined are 8 grams lighter than the previous generation, thanks to refinements to the aluminum carrier.


New SRAM is here!! Effortless performance. Effortless perfection.
