Tiny hubs = big problems?(2 posts)

Tiny hubs = big problems?homiegee

I was looking at the AM Classic Micro hubs, and wondering how they are able to make a hub that only weighs 68 grams that (supposedly) mantains all the proper workings of the 100-200 gram hubs that the largest manufacturers in the world produce. I mean... even ZIPP's newest offering is in the 80's. A friend of mine has them and has had no problem, but he also hasn't ridden his wheels too much. Any experiences with these and/or thoughts? Any shop mechanics who have witnessed the demise of these hubs first hand from the inside?

ok, a number of builders use them to base their wheels on. They are a good hub, relatively speaking. Of course it is not ball bearing. It is all sealed roller bearings that sometimes do go bad. So what? you just take the old ones out, pop the new ones in, inject some grease through grease port and you are all set. Some people have many miles on this hub with no problem. They say it depends from the hub to hub - in some bearings go bad in 200 miles, in others they work just fine. There are also a better quality Swiss made bearings that a guy at Am. Classic had no idea about. LOL!

Overall, i think it is a really good hub that can take an abuse. You just need to watch bearings more often and replace them when they start going rough. If all of them go rough, it may be the problem with axil tolerances or something like that, but i am sure AM will take care of that.

So, no no big problems.
