The Exact Actuation system uses a 1:1 actuation ratio (shifter cable travel : derailleur movement) for 10 speed shifting. This 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.
