The SRAM Force 1 rear derailleur adopts all the technologies of SRAM 1x™ MTB 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. ROLLER BEARING CLUTCH™ technology eliminates derailleur bounce and chain slap without sacrificing precision. This rear derailleur’s “straight parallelogram” design limits all movement to the horizontal axis, which makes ghost shifting impossible while also reducing shift force. For quicker, more exact shifting, the large upper pulley offset design maintains a constant chain gap across all gears.
SRAM X-SYNC 1x chainrings provide the highest level of performance and durability. The SRAM X-SYNC tall square teeth edges engage the chain earlier than traditional triangle shaped teeth. The sharp and narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain. To provide the best possible performance in muddy conditions, the X-SYNC chainrings have been designed with mud-clearing recesses for the inner chain links and rollers. Engineered in Germany, X-SYNC rings are an integral part of the SRAM 1x drivetrain.
When SRAM launched their road technology from scratch, they reapplied their MTB proven SRAM 1:1 actuation ratio (shifter cable travel : derailleur movement). EXACT ACTUATION™ helps to simplify and stabilize the uneasy act of balancing rear derailleur hanger design, tight cog spacing, and exact cable tension. The result: the easiest index shifting system to set up—and it stays that way.
Features:
