DER SRAM RR APEX XPLR D1 12s 44T MAX BK

Description

The Apex XPLR derailleur hits the sweet spot of smooth jumps over a big gear range, all with unmatched chain security and the simplicity of a 1x drivetrain

X-Horizon straight parallelogram design limits all movement to the horizontal axis, which makes ghost shifting impossible while also reducing shift force

Works with 12-speed mechanical Apex and Eagle shifters

Clutch controls chain tension for consistent shifting

Compatible with cassettes with 44T large cogs

Use with FlatTop chains
