Description

The White Industries C157 Rear Hub is a lightweight, precision-machined Super Boost Center Lock disc rear hub built for mountain bikes with 12x157mm Super Boost spacing. We machine, assemble, and inspect every hub in our Petaluma, California facility. As a result, the C157 delivers smooth performance, lasting durability, and premium American craftsmanship.

The C157 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 C157 carries the same proven DNA: simple engineering, dependable performance, and long-lasting reliability.

The C157 is based on our proven CLD+ Boost platform and is designed specifically for bikes that require 12x157mm Super Boost spacing. It uses the Shimano Center Lock disc rotor interface for fast, secure rotor installation and dependable braking performance. Therefore, it’s the ideal choice for riders who demand maximum wheel stiffness, precise handling, and reliable performance on today’s most capable mountain bikes.

At the heart of the C157 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 three spoke drilling options, two anodized colors, and three freehub body options to build the ideal wheelset for your bike. Whether you’re racing enduro, riding technical trails, or building a Super Boost trail bike, the C157 delivers premium Made in the USA performance built to last.

FAQ

Is there a front hub that matches the C157?

The CLD+ Boost front hub is a perfect match, assuming your fork is a 12mm x 110mm or 15mm x 110mm Thru axle.  If for some reason your fork has 100mm spacing, then get a standard CLD front 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 148mm Thru axle?

Yes, but that would be a different model called the “CLD+” Boost hub.  The C157 (which is what you’re looking at on this page) can not be converted to Boost 148mm 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.
