Red eTap AXS Rear Derailleur

SRAM's update to its latest 12-speed AXS eTap groups provide everything we hoped to see from the firm. Shifting customization and firmware updates through its impressive AXS app, exceptional chain retention thanks to its cage damper, and an improved motor and signal travel for faster shifts are just some of the hallmarks that will keep SRAM's technically advanced group, and its Red eTap AXS Rear Derailleur, at the top of the ever so hotly contested road group battle.

The rear derailleur changes extend to its Orbit silicon fluid damper chain management system providing a quiet, secure, and smooth ride even over the bumpiest terrain. Simply put, it reduces chain bounce without placing additional resistance on the derailleur’s spring when under slow or light movement so you still receive easy shifting and rear wheel removals. Its updated motor and signal provide faster and more precise shifting. Large X-SYNC pulleys with ceramic bearings provide extra efficiency and durability while riding and it's compatible with existing eTap batteries. One last thing, it uses the same cage length for 10-26, 10-28, and 10-33t cassettes so you can make changes to your gearing based on the terrain, all while using the same rear derailleur.

A bit expensive for what it provided

I've put it through the wringer

This rear derailleur was easy to install and setup. This replaced a SRAM Rival AXS rear derailleur. I didn’t experience any marked level of improvement in shifting to warrant the extra money. It was only several grams lighter. I was expecting “wow” but what I experienced was “eh”. Maybe the new model will be much better.
