I purchased a mail order bike a few months ago. All my bike wrenching experience is from many years ago. I read up on threadless headsets and indexed shifters so I was good to go. The wheels arrived with some funky looking rubber gumdrop thingies between the cone locknuts and the hub. Spinning the axle with my fingers showed signicant stiction from the rubber things and too tight bearing cones. I adjusted the cones and pried the rubber things off and discarded them, figuring them to be some sort of shipping device. I later thought perhaps they were some lousy engineer's idea of a bearing seal. After looking at some wheel pictures lately, I see that they were seals. My hubs have the normal dust cap ring on them and look just like any cup and cone hub has for decades. Do people really think having that rubber cup rubbing on their hub all the time is a good thing? Maybe if you ford streams everyday but for normal riding I can't see why you would want these. Thoughts?
