SRAM Red eTAP AXS rear derailleur 12 speed Short Cage black

The electronic SRAM Red AXS rear derailleur

Master steep climbs. Whether you're riding the toughest ramps you can find or just keeping your legs fresh for the final climb of a long day, lower gears will get you there.

Rise beyond

Red AXS Short Cage

The heart of the electro ensemble. The SRAM RED eTap AXS ™ rear derailleur, which was developed for both 1x and 2x systems. Thanks to AXS ™, it can be easily adapted to the needs and preferences of the driver. Its advanced Orbit ™ chain control guarantees silent operation in any terrain. With its easier running pulleys and bearings, as well as faster motors and direct signal transmission, the rear derailleur not only makes the switching processes faster.

Red AXS Mid Cage

The SRAM RED eTap AXS 36Z Max rear derailleur works with the XG-1270 10-36 cassette and is compatible with cassettes up to 10-28, so you always have the gears you need. Combine it with the 1x or 2x chainrings of your choice to customize your translations. The Orbit chain management, the X-SYNC pulley wheels and the ceramic bearings ensure peace, efficiency and durability over long distances.

Technical specifications

Technologies used

In this chapter we explain the technologies that the manufacturer uses for this product.

AXS

AXS is the new integrated platform from SRAM to connect electronic bicycle components with the software. The SRAM AXS app enables the driver not only to check the battery level, to influence the switching behavior and to configure the controls according to personal preferences, but also to create maintenance plans and update the firmware.

eTap

Wireless switching, energy management of the batteries and mechatronics - SRAM`s RED eTAP technology serves one goal: to offer you the most intuitive operation possible. We refer to the switching logic behind it as eTAP. The right lever shifts to the higher, the left to the lower gear. You can control the chainrings with both levers. Simple, smooth and intuitive.

X range

Racing bikes are faster and more powerful than ever and the riders keep showing what bikes with racing handlebars are capable of. X-Range is the translation for the modern way of riding a racing bike. SRAM has completely redesigned the racing bike gear ratio, for a wider gear ratio, a more comfortable and more usable gear ratio and, thanks to AXS, also smarter gear settings. With X-Range you are always in the right gear.

orbit

Orbit technology is an innovative and new way to control the movement of the rear derailleur. It uses a silicone fluid as part of an elegant and ultra-light damper system. Compared to a conventional friction clutch system, Orbit technology does not exert any additional resistance on the rear derailleur spring during slow or light movements. This means easier gear changes and a simplified removal of the impeller. And while driving, the fluid damper reduces chain slap. That means a bombproof reliability for single and double drives.

X-Sync

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 and the rounded sloping edges support the chain guide. In order to offer the best possible performance even on muddy terrain, the X-Sync chainrings have recesses for the removal of dirt and mash for the inner chain links and rollers. The X-Sync chainrings made in Germany are an important part of the 1x drivetrain from SRAM.
