Description

The White Industries MI5 Front Hub is a lightweight, precision-machined hub built for road, gravel, touring, and classic mountain bikes with quick-release forks. We machine, assemble, and inspect every hub in our Petaluma, California facility. As a result, the MI5 delivers the smooth performance, lasting durability, and premium craftsmanship riders expect from White Industries.

The MI5 traces its heritage back to the original White Industries Ti Front Hub introduced in 1992. For more than 30 years, we’ve refined our hub designs through real-world riding and continuous innovation. Today, every MI5 carries the same proven DNA: simple engineering, dependable performance, and long-lasting reliability.

Designed with a clean, minimalist profile, the MI5 balances low weight with exceptional strength. Consequently, it’s an ideal choice for road and gravel bikes with rim brakes. At the same time, its durable construction makes it equally capable on loaded touring bikes and classic mountain bike builds. Two premium Enduro sealed cartridge bearings deliver smooth, efficient rolling while requiring minimal maintenance.

Choose from four spoke drilling options and two anodized colors to build a wheelset that matches your bike and riding style. Whether you’re chasing pavement miles, exploring gravel roads, or embarking on a multi-day tour, the MI5 delivers premium American-made performance you can rely on.

FAQ

Which is better, the Mi5 hub or T11 hub?

Neither is “better”, they just have different applications.  The T11 is a lighter weight rim brake road hub and the Mi5 is a little beefier for touring and mountain bikes, but can be used on road bikes if you want a more stout hub.

 

What type of service should I be performing on my hubs, and how often?

This depends on the type of climate you’re riding in, and how often.  To check the bearings, remove the wheel once a month and spin the axle with your fingers to check for roughness which would indicate a bearing/bearings need to be replaced.  In wet climates you can smear extra grease on the faces of the outer bearings to help protect them.  For this, we like to use Sta-Lube Water-Resistant Marine Grease.

 

Can I get this hub in a 12mm x 100mm or 15mm x 100mm Thru axle?

Yes, but you’ll need to call us to order the 12mm x 100mm.   To convert to the 15mm x 100mm configuration, just removed the QR plugs inserted in the axle.

 

Can I convert my Mi5 hub to a 12mm x 100mm axle or 15mm x 100mm Thru axle? And is that and difficult?

You can swap but you may need to purchase a new axle kit depending on what you currently have and what you want to change to.  Axle kits are on the Axle Kits page. Instructions are in the Front Hub Assembly document, but it’s not a complicated procedure and does not require special tools.To convert to 15mm Thru axle just remove the QR plugs

How can I restore that shiny silver finish on my polished raw aluminum White Industries parts?

Use “Mothers Mag and Aluminum Polish” with a microfiber rag.  Start with heavy pressure and lighten up towards the end.

 

Can I get these in a custom anodized color or hole drilling?

Unfortunately we do not offer those options.
