Description

The White Industries CLD+ Rear Hub is a lightweight, precision-machined Boost Center Lock disc rear hub built for modern gravel and mountain bikes. We machine, assemble, and inspect every hub in our Petaluma, California facility. As a result, the CLD+ delivers smooth performance, lasting durability, and premium American craftsmanship.

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

The CLD+ is designed for Boost-spaced frames and uses the Shimano Center Lock disc rotor interface. Therefore, it delivers secure rotor mounting and dependable braking performance on every ride. Its lightweight construction makes it an excellent choice for fast gravel bikes. Meanwhile, its rugged design stands up to aggressive trail riding and demanding mountain bike adventures.

At the heart of the CLD+ is a heat-treated, black-oxide 4130 steel axle with lightweight aluminum axle ends. Four premium Enduro sealed cartridge bearings support the hub—two in the 6061-T6 aluminum hub shell and two in the 6Al-4V titanium freehub body. Together, they provide smooth rolling performance, efficient power transfer, and exceptional long-term durability.

Choose from five spoke drilling options, five anodized colors, and four freehub body options to build the ideal wheelset for your bike. With 100 possible combinations, it’s easy to customize your drivetrain while matching your riding style and aesthetics. Whether you’re racing gravel, riding technical singletrack, or exploring backcountry roads, the CLD+ delivers premium Made in the USA performance built to last.

FAQ

Which is better, the CLD+ hub or XMR+ hub?

Neither is “better”. Both share the same internals and the differences really come down to the two different rotor mounting standards: Center Lock for CLD+, and 6-bolt for XMR+.  The bottom line is you can’t go wrong with either 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.  At least once a year pull the hub apart to inspect and clean/regrease the freehub body parts (pawls etc).  In extreme conditions do this more often.  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.

 

What type of grease do I use inside the freehub body?

We use Lubriplate brand No. 105 grease during assembly. Small, 10 oz tubes are sold as “Lubriplate No. 105 Motor Assembly Grease” at auto parts stores.  This grease has a “NLGI #0” consistency which is similar to brown mustard (that’s how the grease scientists describe it).  But any quality grease with the same consistency (or slightly thinner) will work.  A small amount smeared into the teeth of the Ratchet Ring and in the pawl pockets of the freehub body is all that’s needed.  Too much will interfere with the operation of the freehub pawls and cause skipping.  You can also use Phil Wood Tenacious Oil or Dumonde Freehub Oil if you prefer a bit louder sound.

 

Can I get this hub in a 12mm x 142mm Thru axle?

Yes, but that would be a different model called the “CLD”.  The CLD+ Boost (which is what you’re looking at on this page) can not be converted to a standard 142mm spacing.

 

Can I swap to a different freehub body? And is that difficult?

You can swap from one freehub body to any of the others.  Those are available on the Freehub Bodies page.  If you are swapping to or from a Shimano Micro Spline freehub body, you will also need to purchase the appropriate axle kit on the Axle Kits page.  Instructions are in the Rear Hub Assembly document, but it’s not a complicated procedure and does not require special tools.

 

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.
