>>1924199ah. there are various models of novatech hubs (recognized by the teardrop flange cutouts even if rebranded), some with threaded nuts like pic related. the ones on the state bike are presumably an older/cheaper model. still, maybe they were overtightened for them to go dead within a year. dt swiss road hubs are kind of similar in that the clamping force of the skewer/thru-axle sets the bearing preload.
