hub weight vs bearing friction

896 Views 2 Replies 3 Participants Last post by  Dougal
I overhauled my King hubs this morning and once again noticed that these sealed cartridge bearings, even when fresh and clean, don't roll as well ( the wheel doesn't spin as long) as "loose" cup and cone bearings such as those on the LX hubs on my touring bike. I know that this is due to the increased friction found in cartridge bearings.

I'm planning on rebuilding my racing wheels this winter and was thinking that maybe a pair of loose ball bearing XTR hubs might be a racing performance improvement over my cartridge King hubs despite the fact that they are a bit heavier. Any thoughts?

Noticed similar

I've got CrossmaxSL's which also have sealed bearing and noticed that sealed bearing in general have a different kind of "roll" than ball bearings. As you noticed that have a slight resistance to them, slightly sluggish, though very smooth. I'll defer to other experts that chime in, but I believe under load, the sealed bearings are more efficient.

I've got the same gut feeling. While cartridge bearings have more seal friction, I think with a decent load applied they'd run more freely than cup and cone.

Of course this is just a feeling, I have no proof to back it up.
