Product Details

Overview & Technology

Zipp ZM2 15x110 end cap set is a direct replacement OEM part for ZM2 mountain-bike hubs, designed specifically for front Boost spacing (15x110). Manufactured to the same tolerances as the original components, these end caps ensure axle preload is correct and that your hub bearings sit squarely for smooth, predictable rotation. The caps are finished with a corrosion-resistant anodize and are CNC-machined for consistent sizing and repeatable installation. The product carries the SRAM model ID HU-SPP-A0 and Zipp manufacturer part number 11.2018.064.001, guaranteeing compatibility with ZM2 hub internals and compliance with factory specifications.

Key Features & Benefits

Precision fit: CNC-machined end caps hold bearings and axle interfaces at exact tolerances to eliminate play and reduce premature wear. Proper fitment maintains hub efficiency and extends bearing life. Lightweight, durable construction: Crafted from a high-strength aluminum alloy and anodized for corrosion resistance, these caps add negligible weight while standing up to the knocks and wet conditions of trail riding. As OEM parts, they replicate original geometry for perfect contact surfaces and seal interfacing.

Fit, Compatibility & Installation

This set is intended specifically for Zipp ZM2 hubs in the front 15x110 Boost spacing configuration. Confirm your hub model is ZM2 before ordering — compatibility is indicated by the SRAM model ID HU-SPP-A0 and Zipp part number 11.2018.064.001. These caps will not fit non-ZM2 hub families or hubs with different axle standards. Installation is straightforward for home mechanics with basic tools: gently press the caps into the hub shell until they seat flush. Use a soft-faced mallet or a sized socket as a drift; avoid over‑driving. Grease contact surfaces lightly, check bearing preload after installation, and torque any through-axle hardware to manufacturer specs. If unsure, have a qualified mechanic install them to protect bearing seals and hub integrity.

Who This Is For

This end-cap set is ideal for mountain bikers who need an exact OEM replacement for a damaged or lost front ZM2 end cap, or for riders converting/servicing hubs to the 15x110 Boost configuration. It’s for people who value precision parts that retain original hub performance and longevity. Mechanics, wheel builders, and home grease-monkeys who maintain ZM2-equipped wheels will appreciate the match-to-factory fit and the peace of mind that comes with a genuine Zipp replacement part.

Frequently Asked Questions

Will these end caps fit any Zipp hub?

No. These end caps are made specifically for Zipp ZM2 front hubs in the 15x110 Boost spacing. They will not fit other Zipp hub models or different axle standards. Check your hub model and spacing before purchasing.

How do I install the ZM2 15x110 end caps?

Installation is typically a press-fit operation. Lightly grease mating surfaces, align the cap squarely on the hub bore, and press using a soft-faced mallet or an appropriately sized socket as a drift. Avoid excessive force that could damage seals; if unsure, have a professional fit them.

Can I replace damaged end caps myself?

Yes — if you have basic mechanical skills and the right tools. Replacing caps is straightforward, but careful seating and checking bearing preload after installation are important. If seals or bearings look compromised, replace or service them at the same time.

Are these end caps compatible with Boost adapters or thru-axles?

These caps create the correct internal interface for a 15x110 Boost front axle for ZM2 hubs. They are not universal 'adapters' for other axle sizes—use them only where ZM2 hub geometry and a 15x110 axle are specified.

What materials are the end caps made from?

The end caps are CNC-machined from a high-strength aluminum alloy and finished with an anodized coating for corrosion resistance. This combination provides a light, durable component designed to match factory tolerances.

Do these come with seals or bearings?

No — this listing is for the end cap set only. Bearings and hub seals are separate components. Inspect your bearings and seals during installation and replace them if they show wear or contamination.

Buying Guide

When buying replacement end caps for a hub, always verify hub family and axle spacing first. OEM parts like this Zipp ZM2 15x110 set match original tolerances and materials, ensuring correct bearing preload, seal engagement, and safe wheel function. Consider replacing bearings or seals at the same time if they show wear; the small cost of matched components prevents premature failure and protects your investment in wheels. If you're unsure about fit or installation, consult a trained wheel builder or your local bike shop.
