Hubs

Sealed Bearings

Cartridge bearings with weather resistant seals are used on most of our hubs.  Race hubs are designed with Cyclocross in mind and have improved, double bearing seals for even more protection against the elements.  Sealed does not mean waterproof.  If your bearings are submerged in water or subject to a pressure washer or invasive cleaning, you should have them serviced or replaced by a professional mechanic.  Our bearing preloads are set from the factory; there is no need to adjust them.  All of our sealed cartridge bearing hubs include an internal cam quick release.

Loose Ball Bearings

Properly adjusted cup and cone hubs will spin as smooth as a sealed bearing hub.  All of our cup and cone hubs are designed with excellent seals to keep grease in and everything else out.  Adjusting cup and cone hubs is an art, and should be performed by a professional mechanic.  Loose ball bearing hubs do not include quick releases.

Quick Releases

Internal cam quick releases offer a few advantages over their external cam counterparts.  The entirety of the tightening mechanism is enclosed inside the lever, keeping the moving parts clean and effective.  This allows for more tension on the dropouts with less effort at the lever.  When installing wheels on chrome or stainless dropouts, internal cam quick releases are a must.  Quick releases are included with every sealed cartridge bearing wheel and hub that we offer.

Convertible Hubs

Mountian bike technology is evolving quickly.  There are at least three common front wheel axle standards and two common rear wheel axle standards.  Our convertible hubs can handle them all, without the need to change hubs as technology evolves.  ATB Convertible Disc front hubs include all necessary parts to switch between 9mm quick release, 15mm thru axle, and 20mm thru axle standards.  Lightweight ATB Disc rear hubs are designed to transition from 135mm quick release to 142mm thru axle with an additional conversion kit.

Servicing a Cassette Body

Cassette body pawls are what transfer your power to the ground.  They should be inspected and re-lubricated once a year, or more depending on use and environment.  

Radial Lacing

All of our front hubs are designed to facilitate radial lacing when appropriate..
