The right cap keeps your ZR1 hub running true. Don't race on worn hardware.

The Zipp Axle End Cap Set Rear is the genuine OEM replacement for ZR1 rear hubs. End caps are wear items — they take the clamping load from your thru-axle every time you seat the wheel, and over thousands of rides they wear, crack, or get lost during travel. This set covers both 12×142 XDR and 11-speed configurations, so one purchase solves the most common ZR1 rear dropout setups.

ZR1 hub only. These end caps are specific to the Zipp ZR1 hub platform and are not compatible with ZR2, 77/177, or other Zipp hub generations. Check the engraving or label on your hub shell before ordering — it will read "ZR1" if this is the right part.

What makes this worth it

Genuine Zipp Part

OEM end caps engineered specifically for the ZR1 hub. Same precision tolerances as the caps that shipped with your wheels — not aftermarket.

Dual Compatibility

Fits both 12×142 XDR and 11-speed thru-axle standards. Covers the two most common rear dropout configurations on modern road and gravel frames.

Extends Hub Life

End caps take the axle clamping load so your hub shell doesn't. Replacing worn or damaged caps is the cheapest service job you can do to extend ZR1 hub longevity.

Sold as a Set

Includes all end caps required for the rear hub configuration. Replace both sides at once for consistent interface performance.

ZR1 Hub Specific

Designed for the Zipp ZR1 hub platform. Not interchangeable with ZR2, 77/177 or other Zipp hub generations — check your hub model before ordering.

Light & Easy to Store

Small enough to carry in a travel kit. If you race or travel with your Zipp wheels, keeping a spare set means you're never stranded by a damaged cap.
