SRAM RED XPLR E1 rear derailleur – a wireless 13-speed AXS derailleur built for gravel bikes running a single front chainring.
Key features:
Speeds: 13-speed – one more cog than standard XPLR setups, so the steps between gears are smoother.
Max cog: Up to 46T – enough for long loaded gravel climbs.
Control: AXS wireless – no cables, electronic shifting, settings adjustable from your phone in the SRAM AXS app.
Drivetrain: 1x – built for a single chainring, no front derailleur needed.
Battery: NOT included – uses the standard SRAM AXS battery shared across all AXS components.
Summary:
This is SRAM's top gravel tier. If you are building or upgrading a RED XPLR drivetrain, this derailleur is its heart – just remember the battery separately if you do not already have one.
