I think that travel range sounds pretty accurate. Personally, I just upgraded from a black to a sherman flick with the adjustable travel an I'm liking it. I was trying to decide between the z1 fr3 or it, and decided to go with the sherman for the travel adjust. Also, I was a little confused as to how much travel the z1 had because marzzochi listed it with 130, but jenson had them on sale and said they were 150.
