The completely redesigned Terralogic inertia valve senses changes in terrain, instantly providing optimal firmness for maximum pedaling efficiency, or full, plush travel for worry-free front-end control.
Strengths: Wow all I can say is this fork is awesome! It wasnt the cheapest, but I definitely think I could not have found a better fork for my Specialized Epic 29er. Very supple action once engaged by bumps....really cant tell when it is working it is so smooth. Full travel use on this 2011 model with Kashima. Solid steering...super easy set up...air it up and set the brain to 3 and ride it!
Weaknesses: If I had to whine, price....these are not cheap.
Bottom Line:
If I had to spend the money again I would without hesitation. On my second season and no complaints about anything. New brain action is super smooth!
