Mavic 9x135 rear wheel adapter

Mavic 9x135 adapter installation: everything you need to know for your rear wheel

When it comes to ensuring compatibility between your bike frame and wheel components, one item often comes up: the Mavic 9x135 mm adapter. This small yet essential piece plays a crucial role in the rear wheel setup, especially when you want to use a Mavic hub on a frame with a 135 mm quick release (QR) dropout spacing and a 9 mm axle.

In this article, we’ll walk you through what this adapter does, its technical specs, and how to install it properly.

What is a Mavic 9x135 mm adapter for ?

Many Mavic rear wheels, especially those equipped with ITS-4, FTS-L, or ID360 hubs, are designed to be modular and compatible with multiple axle standards. The Mavic 9x135 adapter allows you to convert a wheel originally intended for thru-axles or other formats into a quick release setup — specifically a 9 mm axle with 135 mm spacing.

It’s an essential conversion kit for riders who want to fit a modern Mavic wheel onto an older or more traditional mountain bike or hybrid frame.

Key features of the Mavic 9x135 adapter

• Compatibility: Fits rear Mavic wheels with convertible hubs, including Crossmax, Deemax, Aksium, and more.

• Format: Designed for 9 mm QR axles with a 135 mm dropout width.

• Material: Typically machined from aluminum or steel for maximum strength without unnecessary weight.

• Easy Installation: Consists of two end caps (left and right) that slide onto the hub axle ends.

How to install the Mavic 9x135 adapter

The Mavic 9x135 adapter installation process is straightforward, requiring only basic tools and a little patience. Follow these steps:

1. Remove the original end caps from the hub if the wheel is currently set up for a different axle standard (e.g., 12x142 mm, Boost, etc.).

2. Insert the Mavic 9x135 end caps on both sides of the hub axle. Most of the time, they snap into place by hand. Use a plastic tool if needed to avoid damaging the parts.

3. Install the wheel on the bike frame just like any standard quick release wheel.

4. Tighten the QR skewer securely, making sure the wheel sits straight between the chainstays.

A correct installation ensures even clamping force, smooth freehub rotation, and a solid connection between the axle and the dropouts.

Why choose an adapter instead of a new wheel ?

An adapter is often a much more cost-effective solution than buying a new wheel. It allows you to reuse a high-quality Mavic rear wheel, adapt to your bike’s current frame setup, and maintain flexibility if you change frames in the future.

Plus, Mavic adapters are built to preserve the performance of the hub with no compromise in drivetrain efficiency or ride feel.

In summary

The Mavic 9x135 adapter installation is a smart, simple, and affordable way to make your Mavic rear wheel compatible with a standard frame. With the right end caps and a careful setup, you’ll enjoy all the benefits of a premium wheel — even on a frame using a traditional QR system.

Whether you ride MTB, gravel, or hybrid, this adapter ensures a perfect fit without sacrificing performance.
