Front Hub Service
Component Removal
The hub can be serviced while in the wheel. However, if your spokes or rim are damaged, you can remove the hub from the wheel which will make
servicing your hub easier. To remove the hub, use a spoke wrench to de-tension the spokes, then use a pair of metal snips to cut the spokes, remove
the hub from the wheel, and remove the spoke ends from the hub (not pictured).
For additional information about Zipp wheels and hubs, user manuals are available at www.Zipp.com.
