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.

Great looking piece of kit

Yes, I recommend this product.
Pros: Good quality, Lightweight, Looks great
I bought this to compliment my trek frame as it suited the colour scheme. The X0 really looks the part when fitted and provides very slick and precise operation of the gears. There is strong spring tension in the cage to prevent chain slap on rough descents which appears to work well so far. It's certainly not the cheapest rear mech on the market but you do get a well made product with the added bling factor thrown in
