SRAM Apex XPLR D1

The SRAM Apex XPLR D1 is a 1x12 mechanical rear derailleur with 44T capacity, X-HORIZON design for chain security, and a mechanical clutch. It suits adventure and gravel cyclists seeking smooth, durable shifting across wide gear ranges.

• You want your bike to do everything, so you need gears that can do everything. 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. Quietly and quickly shift across 12-speed cassettes with 44T large cogs knowing you'll have the gears you need.
• Compatible with cassettes with 44T large cogs
• Use with Flattop chain
• Works with 12-speed mechanical Apex and Eagle shifters
• Clutch controls chain tension for consistent shifting
• X-HORIZON straight parallelogram design limits all movement to the horizontal axis, which makes ghost shifting impossible while also reducing shift force
