The SRAM Force 1 Rear Derailleur (originally known as the CX 1) borrows from the technology of the hugely successful SRAM 1X mountain bike groups to provide the fastest, quietest 1x11 shifting available. SRAM's unique clutch system eliminates chain slack, providing for smoother, quieter, and more secure chain travel. It is part of an incredible 1x drive train perfect for cross, gravel bikes, and with the 130 spider crank even Criterium and TT bikes.

This SRAM Force 1/CX 1 rear derailleur's unique straight parallelogram design limits all movement to the horizontal axis, which makes ghost shifting impossible while also reducing shift force. The large 12t upper pulley offset design maintains a consistent chain gap across all gears. This puts the upper pulley in the perfect position for the quickest shifts across the entire range.

Roller Bearing Clutch™ technology reduces bounce and chain slap. Cage Lock™ technology makes wheel removal and installation easier than ever before. Cage Lock lets you push your cage forward and lock it into place with the push of a button. This creates slack, removing all tension from the chain. With Cage Lock, wheel removal and installation - as well as chain installation is easier than any other derailleur.... Read More
