CLD+ Boost Rear
Price range: $382.90 through $451.00
Our CLD+ (Center Lock Disc) Boost hubs are designed around the Center Lock splined rotor mounting interface as opposed to the 6-bolt mounting standard used on our XMR hub. The Boost spacing allows for wider hub flange spacing which results in better spoke bracing angles. Made in our shop from U.S. sourced 6061-T6 aluminum, they’re available in a range of drillings, colors, and axle configurations.
A question we always get about our disc hubs is, “CLD or XMR? Which is better?”. Neither is “better” than the other. Both share the same internals and the differences really come down to the respective designs having to accommodate the two different rotor mounting interfaces. Bottom line is you really can’t go wrong with either hub!
Most of the time choosing is simply a matter of which disc rotor system you already have on your bike, so your choice is kind of made for you. And if you’re building a new bike, it’s not a bad idea to stick with the rotor system you’re using on your other bikes, just in case you want to swap things around. And to add to it, Shimano and SRAM don’t offer all their rotor models and sizes in both Center Lock and 6 bolt, so be aware of that when speccing out your new rig.
Product Details
As with all our hubs, the CLD+ (Center Lock Disc Boost) draws on over 30 years worth of hub manufacturing experience and real world testing, going back to the “Ti Cassette hub” we introduced in 1992. We’ve been doing this for a long time, and every White Industries hub we make has that original DNA in it; simple, durable, dependable. The CLD+ is perfect for Boost spaced gravel and mountain bikes because of their low weight and clean, minimalist look, as well as their robust and durable design. Designed around the Center Lock splined disc rotor mounting standard, the core of the rear CLD+ is a heat treated, black-oxided 4130 steel axle with aluminum axle ends, rotating on four Enduro brand bearings: two in the 6061-T6 aluminum hub shell, and two in the 6/4 titanium freehub body. CLD+’s are made here in our Petaluma, Ca. shop, and available in five spoke drillings, seven colors, and four different freehub bodies. That’s 140 different variations!Specs

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 Parts>Hub Parts>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 Parts>Hub Parts>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.
