Track Axle Cap Kits

For older Zipp® track wheels without a solid threaded axle, these track caps thread into the axle to hold the wheel firmly in place. They also have a bad habit of disappearing on the infield of the track so it's always good to have a couple of back-up sets.

Order one kit (two caps and two bolts) per wheel. When ordering, please specify which of the three bolt sizes you need.


• Short black bolt fits old 404 track rear and old rear discs with black flanges.

• Long black bolt fits old 404 track front. Long silver bolt fits old 90-01010 front track disc.
