I had this annoying sqeaking/creaking sound coming from the front end of my bike for the past couple weeks. I completely tore apart the headset, bars, stem, shifters, etc and regreased everything. Creaking still there! I finally figured out it was coming from the front hub. I've taken it apart and now have two rusty sealed bearings, end caps, and an axle sitting in front of me. Oh, by the way, the front wheel is a Velomax Tempest. The only thing the bearings have written on them is "china" and "R6RS".
Are there different types of bearings? Some better than others? I remember a conversation once about ceramic bearings, I think. Can I order these bearings online? I was trying not to go to my LBS but will if I have to.
