I have these on some wheels but chanegd the ratched system. I never tried the 72T version because i didn't read much good about that from a longevity perspective. I ride all year in the UK and have done about 2000 miles on my wheels since October. They are really loud, i am using 36T ratchet and I checked the ratchet recently and all looked good. Just gave it all a good clean and put back together.
The HG freehub i have is like cheese. It didn't take long before the sprockets had worn badly into the splines because the splines have much less material on them. I bought a replacement but yet to fit it, shifting is still okay and overall been super happy with the hubs. Bearings still smooth and nothing corroded inside.
Perhaps not a great insight to this specific version of the product but overall super happy with the goldix hubs and have two light XC wheelsets with them.
