I received a headset branded as ZTTO. I plan to upgrade my suspension fork to a tapered fork and needed a new headset to replace the caged stock bearings. After researching the correct size of my head tube, I found the correct size headset with this one.I measured the cups outer diameters and they fall within the specs listed. This set even comes with the 1 1/8” adapter to fit a straight tube fork with the included crown race. Also included is a star nut which is a major plus. Now I have everything I need when I select a new air fork.The only negative I can think of is the lack of specs on the bearings. If I were to ever need to replace them I will have to measure them and match them with the same size bearings. The cups themselves are branded and labeled with the correct cup type and size.
