SRAM RED eTap AXS D1 12-Speed Short Cage Max 33T Rear Derailleur

SRAM RED eTap AXS D1: 12-Speed Electronic Rear Derailleur

The SRAM RED eTap AXS D1 is the electronic rear derailleur from the SRAM RED eTap AXS road groupset. It features 12-speed shifting and SRAM AXS technology for wireless electronic control.

This version features a short cage and is designed for cassettes with a maximum sprocket of 33 teeth. It is intended for 2x road drivetrains.

Wireless Electronic AXS Shifting

SRAM AXS technology eliminates the need for a traditional mechanical shift cable. The rear derailleur receives electronic commands from compatible AXS components, managing rear shifting wirelessly.

The AXS ecosystem also allows electronic adjustment and fine-tuning of the drivetrain, including MicroAdjust functionality for precise rear derailleur positioning.

Short Cage and 33T Maximum Capacity

The RED eTap AXS D1 uses a short cage and supports a cassette with a maximum sprocket of 33T. SRAM specifies a minimum cassette sprocket of 26T or 28T for this rear derailleur.

The 2x configuration makes it suitable for compatible SRAM road drivetrains, combining electronic rear shifting with a clean setup free from a traditional shift cable.

Carbon Cage and Ceramic Pulley Bearings

The rear derailleur features a carbon cage and pulley bearings made with ceramic bearings, specifications of the RED eTap AXS D1 model.

This combination of materials and components complements the wireless electronic AXS system and its road-focused design.

Electronic Drivetrain Control

With the SRAM AXS ecosystem, the rear derailleur communicates electronically with compatible components without using a traditional mechanical shift cable.

The AXS platform also allows drivetrain settings to be managed electronically, helping simplify rear derailleur setup and adjustment.

Road Flattop Chain Technology

The RED eTap AXS D1 uses Road Flattop D1/E1 chain technology, part of SRAM's road AXS drivetrain ecosystem.

A High-Performance Electronic Road Rear Derailleur

The SRAM RED eTap AXS D1 combines wireless shifting, AXS technology, 12-speed gearing and a short-cage design with a maximum 33T cassette sprocket.

The carbon cage and ceramic pulley bearings complete a component designed for a 2x electronic road drivetrain, offering wireless shifting and electronic adjustment through the SRAM AXS ecosystem.
