Ultra Seal Ceramic | NOVATEC, D256SBT-14H-11T (MTB) - REAR HUB
Our Ultra Seal line of ceramic hybrid bicycle bearings are specially designed for On Road and relatively clean riding environments. These bearings are maintenance free and lubed for life. The non-contact seal eliminates any drag typically associated with a rubber sealed bearings and still provides extra protection against external elements. All sealed bearings are packed in grease and will require a short break in period to loosen up.
