I'm going to need to replace my 20" rear wheel soon and am looking at my options. Right now I have a 48 spoke alex mx22 on a loose ball bearing 14mm hub. I want a cartridge bearing hub (preferably flip-flop) with a crome rim. I am trying to decide between Alex Supra-G, Demolition, or Primo Hula Hoops for rims and am having a tough time finding cheap flip-flop hubs that I could order through my shop. Should I stick to a regular hub? By that I mean are they more durable than flip-flop hubs because of the larger bearings? I definately don't want cassette but am considering going to compact drive with a 14t freewheel. Let me know your good and bad experiences with hubs. I don't think I could go wrong with any of those rim choices
