sealed bearing hubs

[young Ed]

Sealed = Zero maintenance, once worn replace bearing
Non sealed = All the moving parts can be replaced, bearing is adjustable.

Its all down to personal preference, I prefer to bin the old bearings and pop fresh ones in, but remember some hubs that have sealed bearings mean just that, they are sealed into the hub, when worn out that's end of life for the hub.

i would make sure i get the ones like in my 2 photos in the original post as i know for a fact those bearings sealed and ready to pop in are available everywhere and cost next to nothing!
Cheers Ed

Most hubs will come with standard sized sealed bearings, formula hubs seam to be quite cheap .

Sealed bearing hubs are easy to make, but not necessarily better. Also, what the bike trade refers to as 'sealed' are actually 'shielded'. To be reliably weatherproof they need additional protection.
