Sram Rear Derailleur Apex Xplr Black

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 our 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
