Good quality, looks wrong - May 10, 2015

This was the best quality headset I found online for the ZS 44/ZS 55 (not 56!) frame on my Fuji Outland. LBS was able to press it in no problems. No wobbles and turns very freely. I marked this down one star because the headset shipped isn't the one pictured. The FSA Gravity SX Pro I received had a much taller top piece, so much so I had to remove a large spacer to accommodate it. Cosmetically I like it, but it was irritating trying to figure out if it was the right part or not. You can Google Image Search the headset model name to see the real look.
