Product Description

SRAM has always offered innovative ways to implement 1x drivetrains on racing bikes. With the SRAM RED eTap AXS, these possibilities have been significantly improved once again. This chainring is designed for situations where you are riding alone in the wind for a long time, showing its advantages especially in triathlons and time trials. The aerodynamic advantage results not only from the omission of the cut-outs in the chainring, but also from the absence of a front derailleur. In addition, this chainring is particularly stiff, so your acceleration is immediately translated to speed.

AXS is SRAM's new electronic integration platform that combines electronic bicycle components and software. The SRAM AXS app allows drivers to view battery status, change component behaviour, adjust controls, receive maintenance reminders, and update firmware.

X-Sync 1x chainrings from SRAM ensure maximum performance and durability. The long SRAM X-SYNC tooth edges grip the chain earlier than traditional triangular teeth. The sharp and narrow tooth profile as well as the rounded bevelled edges support the chain guide. To provide the best possible performance even in muddy terrain, the X-SYNC chainrings have recesses to remove dirt and mud from the inner chain links and rollers.


  • SRAM X-SYNC offers maximum chain control
  • Improved aerodynamics for time trials and triathlon
