seems sturdy enough. though the build quality is cheaper than I would have imagined, though I can't complain for the price. I just wish the bearings were smoother, as I can feel the uneven finish on them as I turn the axle. I really wish they would provide the diameter of the hub ( it's 48.5mm) in the description because it's a key factor in buying parts like this, especially if replacing a broken hub like I was, and not wanting to buy spokes as well.
It is an old school cup and cone loose bearing set. This requires some extra maintenance compared to sealed bearings and a small amount of drag when properly adjusted.
