Just going to add my experience. I have built multiple sets of wheels around Bitex hubs from bikehubstore (Brandon is awesome). The oldest is 5+ years, on its second set of front bearings and still going strong. Riding the next oldest on my cross bike, 24/28. Those hubs are on their second set of rims and new bearings for the front hub, still going strong. I've built two sets of the mtb hubs; rode the piss out of one set and have sold the bike, never having replaced any bearings on the hubs (didn't need to). Last mtb set is on my current full-sus steed.
I have been super happy with the hubs; honestly would not buy anything else right now as they hit the right quality
rice ratio for me.
