The Campagnolo Athena hubs are forged using Campagnolo's renowned aluminium alloy and use the race proven cone, cup and ball bearing system 3/16" balls in the front and 1/4" in the rear. The inner mechanism is protected from contamination by two metal, not plastic, covers with provisions for direct lubrication without disassembly.

The system eliminates the power robbing frictional drag associated with so called "sealed" bearing systems. The patented quick release, now a standard feature on most hubs, was invented by Campagnolo and features a positive locking lever and an easy to use adjusting nut. Hubsets are available in 32 and 36 hole.
