I'm tired of Halo MT supadrive hubs and their strange issues. But I am too broke to currently buy another rear hub before I get some income from my summer job.

current problem all major hub manufacturers currently use 6802 bearings for microspline freehubs such as the new one up hub, my halo hub and many others, this is due to the fact that having the bearing sit on the thru axle is a bad idea as loading the axel in shear while it is under tension is a recipe for breaking many many axels, and that standard bearing sizes come only come in 12,15, and 17mm ID sizes. meaning that your bearings must have a 15mm ID and for microspline a 24mm OD to fit inside the freehub . These bearings are just barely adequate for use in free hubs and generally see short service lifes unless doubled up or using a double row bearing as seen in hopes new pro5 design. In red the bearing type, in purple the rated static load of the bearings, (dynamic is 2x static for almost all cases).

One up uses only two 6802 bearings in its free hubs meaning half of the load capacity.
