Product Details

ZR1 Axle — Overview & Technology

Zipp's ZR1 axle is a factory-replacement rear axle engineered specifically for the ZR1 hub family. Supplied with the drive-side bearing (DS) and a precision wave spring, this axle carries SRAM Model ID HU-SPP-A0 and Zipp part number 11.2018.064.013. Two variants are offered to match brake systems: a disc-brake specific axle and a rim-brake specific axle. The axle is a precision-machined, high-strength steel unit designed to restore hub alignment, bearing preload and wheel tracking after service or damage. The included wave spring provides consistent axial preload for reduced play and longer bearing life, while the drive-side bearing ships pre-installed to simplify rebuilds and swap-outs.

Key Features & Real-World Benefits

What you get: • Complete axle assembly — axle, drive-side cartridge bearing and wave spring included. • SRAM cross reference — HU-SPP-A0 for easy compatibility checks. • Brake-specific variants — pick the correct disc or rim brake version to maintain correct axle spacing and clearance. In practice this means faster, more reliable wheel service: the wave spring keeps the bearing preloaded and eliminates slack that causes noise and premature wear, the precision axle restores correct hub geometry, and the pre-installed DS bearing gets you back on the road quickly with minimal press work.

Fit, Compatibility & Installation

This axle is a direct replacement for Zipp ZR1 rear hubs — verify your hub type before ordering. The product number 091003 and manufacturer part # 11.2018.064.013 match Zipp's ZR1 service parts; the SRAM ID HU-SPP-A0 is a helpful cross-reference when checking compatibility with workshop inventories. Note the two variants: one tailored for ZR1 disc-brake hubs and one for ZR1 rim-brake hubs — they are not interchangeable. Installation is straightforward for a bike mechanic: remove the wheel from the frame, extract the old axle and bearings, and install the axle, wave spring and drive-side bearing to factory tolerances. While many home mechanics can complete the swap with basic tools, a bearing press, torque wrench and the hub service manual ensure proper bearing seating and preload — if unsure, have a shop fit it to avoid damage.

Who This Axle Is For

This part is intended for road cyclists and mechanics who own or service Zipp ZR1 wheels — from racers preparing wheels for an event to shop techs stocking genuine Zipp service components. It's ideal when a wheel has axle damage, excessive play, or after a hub rebuild when replacing worn internal parts. Also useful for fleet maintenance or racers who value OEM-fit components: buying the correct Zipp ZR1 axle restores hub performance, keeps bearings functioning smoothly, and preserves original wheel alignment and reliability.

Frequently Asked Questions

How do I know which variant (disc or rim) I need?

Check your Zipp ZR1 wheel's brake type — disc-rotor hubs require the disc variant and rim-brake hubs require the rim variant. Confirm part # 11.2018.064.013 or SRAM ID HU-SPP-A0 against your hub documentation before ordering.

What's included in the axle assembly?

The ZR1 axle assembly ships with the rear axle, the drive-side (DS) cartridge bearing pre-installed, and the wave spring for correct axial preload. Other hub bearings or end caps are not included unless specified.

Can I install this axle at home without special tools?

Basic removal and installation can be done at home, but proper bearing seating and preload are best achieved with a bearing press and torque wrench. If you lack tools or experience, a professional wheel mechanic will ensure correct fit and avoid damage.

Is the included bearing sealed?

The included drive-side bearing is a cartridge-style bearing designed for hub use. It is factory-sealed to keep lubricants in and contaminants out, but regular inspection and maintenance are recommended depending on riding conditions.

Can I use the disc variant on a rim brake hub (or vice versa)?

No. Disc and rim variants are designed to match the hub spacing and clearance requirements of their respective brake systems. Using the wrong variant can cause misalignment or improper preload — always pick the correct version.

What is the SRAM Model ID HU-SPP-A0?

HU-SPP-A0 is SRAM's cross-reference identifier for this Zipp axle assembly. It helps shops and parts databases match service items across brands and simplifies ordering replacement components.

Buying Guide

When replacing a hub axle on a Zipp ZR1 wheel, always match the exact hub variant — disc or rim — and confirm part numbers (11.2018.064.013) or SRAM cross-reference HU-SPP-A0. Decide whether you need just the axle or a more complete hub service kit with both bearings and end caps; the ZR1 axle includes the drive-side bearing and wave spring, which handles the most commonly replaced components during routine service. If you're servicing wheels regularly or preparing for races, keep both variants in your spares kit so you can perform same-day repairs. For one-off replacements, have a professional install the axle to ensure proper bearing seating and preload and to protect your wheel's longevity.
