Tech Feature: 12-Speed SRAM RED eTap AXS

On 6 February, SRAM introduced a high-performance wireless groupset – the SRAM eTap AXS – and it has taken the bicycle market by storm. Let’s take a look at some of the features of the SRAM eTap AXS Groupset.


SRAM Red AXS Drivetrain Components and Features  


The SRAM Red Crankset provides a greater range and smoother gear progression with their Deep Range gearing technology. SRAM has moved the range from the front of the drivetrain to the back, and maintained a consistent 13-tooth gap across all variants of chainring duos.

SRAM claims that they have improved the front shifting performance and created a lighter, stiffer, and more durable crankset. The integrated chainring design significantly reduces weight, and a DUB bottom bracket adds durability and simplicity.

Are you thinking about upgrading your crankset with a power metre to calculate those marginal gains? Consider SRAM’s Red 1AXS Crankset that comes with a power meter. A single-ring drivetrain set-up simplifies functionality and will greatly significantly benefit you especially if you are a time triallist, triathlete, or a cyclocross racer.

The 48 and 50t variants feature a fully integrated power metre into a direct mount aero chainring, while the 36-46t variants have a spider-based power metre. 

The power metre is capable of producing a +/-1.5% reading accuracy that isn’t affected by climatic conditions during a ride.

Could this be the “most responsive, quick, and precise front shifting to date”?

The SRAM Red eTap AXS Front Derailleur has been designed to allow for greater rear tire clearance. Their classic SRAM Yaw trimless cage technology features an optimised cage profile.

SRAM states that its Orbit chain management technology keeps its drivetrain quiet and secure. The SRAM RED eTap rear derailleur also features an improved motor and signal travel for faster shifting, and larger pulleys and ceramic bearings for increased durability and efficiency. It is compatible with existing eTap batteries. 


Shift-Brake Lever

Do you have short fingers and always face the problem of reaching your brakes comfortably? With SRAM Red’s shift-brake system, you can personalise the brakes and shifters for your hands using their Contact Point Adjustment and separate Reach Adjust. 

It also features newly textured shift paddles and hoods for a better feel. The SRAM Red eTap AXS Shift-Brake Lever is available in both flat mount and post mount options.

Each cassette features a 10-tooth small cog and is designed specifically for wireless electronic shifting.

SRAM claims that this updated cassette design improves shift performance as it allows for more gradual gear progression between cogs – at least five one-tooth jumps.

Other Add-ons

SRAM Red Chain 


The SRAM Red Chain features a unique link shape which allows the chain to be narrower and lighter while increasing strength and providing more tolerance between cogs.

SRAM’s CentreLine XR (CLX-R) rotor is designed specifically for road bikes and complements the SRAM eTap AXS Drivetrain. The Centreline track offers quiet brake operation, and the two-piece design reduces weight.
