Zipp 333 track hubs were redesigned to improve stiffness required for the rigors of track racing. The 333 makes use of oversize bearings and axle to maximize lateral stiffness. The rear hubshell incorporates asymmetrical hub flanges to help balance left/right spoke tension.

Hub flanges of the 333 are angled inward to provide a smoother path from a j-bend spoke straight to the rim.

The 333 hubset is easy to service as well. Removing the wheels from the bike is handled with a common 6mm Allen wrench. Likewise, axle locknuts are made to interface with standard open end wrenches, rather than cone wrenches to make bearing access easier.
