About SRAM Force A1 10 Speed Rear Derailleur

10-speed Compatible

Technology
Exact Actuation: When SRAM launched their road technology from scratch they reapplied their MTB proven SRAM 1:1 actuation ratio (shifter cable travel : derailleur movement). EA helps to simplify and stabilise 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.
