Are these hubs really disposable?

On the 2001 Bianchi Daytona SL Aluminum bike I have, the hubs are Bianchi Levitation.

Are these hubs truly disposable?

I don't see anywhere that I could possibly get at the bearings.

The interior of the axle is round. The exterior also doesn't appear to have anywhere I could use a wrench, pliers, etc.

Are you really supposed to just throw these hubs away when they wear out?

looks like cartridge bearing hubs, the bearings are replaced as a unit and are pressed in/out

looks like you can fit a 5 or 6mm allen key in there.

Doh! I used my Chimpanzee brain and was able to pull the end cap right off.

Is there a trick to getting the cartridge out. I tried prying with a utility knife but it seems pretty tight.

Assuming you can remove the axle, this is a typical cartridge bearing removal tool: http://www.jensonusa.com/store/produ...ng+Puller.aspx

Note, you should be able to see a number on the bearing, and that number probably corresponds to an Annular Bearing Engineering Committee number, see http://en.wikipedia.org/wiki/ABEC_scale. You can purchase this bearing at an industrial supply shop.

I'll leave you with this link to the Neuvation tech page, they might be Neuvation wheels after all. Not 100% sure though...

looks like you can knock the bearing out by striking the axle. new bearings can be pressed with various methods, i like the press from wheels mfg.
