That's Z as in Zero Stack, my friend. Designed primarily for mountain bike use, the low-profile Cane Creek-compatible FSA Orbit Z Headset rolls on sealed angular contact bearings for silky smooth, trouble-free performance. Adjust it when you install it and you're good to go for years, because the Orbit Z requires virtually zero maintenance.
