XMR Front
Price range: $217.00 through $242.00
Our XMR (Cross/Mountain/Road) hubs are designed around the ISO 6-bolt rotor mounting interface as opposed to the Center Lock mounting standard used on our CLD hub. The 6-bolt system requires a slightly larger flange diameter which allows for a classic look with machined “windows” in the flanges. From road bikes to trail bikes, the XMR is a solid choice for 6-bolt set ups. 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. The CLD has a more compact look and is slightly lighter while the XMR has larger flanges which allows those really cool “windows” to be machined into them. 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 XMR (Cross Mountain Road) draws on over 30 years worth of hub manufacturing experience and real world testing, going back to the “Ti Front 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. For those of you committed to the 6 bolt disc rotor standard, the XMR’s are perfect for mountain and touring builds due to their robust and durable design, but they are equally at home on road and gravel bikes because of their low weight and classic high flange design. Designed around the ISO 6 bolt rotor mounting standard, the XMR rotates on two Enduro brand bearings, and are made here in our Petaluma, Ca. shop. They are available in six spoke drillings, seven colors, and three axle configurations. That’s 126 different variations!Specs

FAQ
- Which is better, the XMR hub or CLD 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. Also, the XMR has larger flanges with window cut outs, and some may prefer that look over the smaller CLD flanges without windows. 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. 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 Boost 15mm x 110mm Thru axle?
- Yes, but that would be a different model called the “XMR+”. But the standard XMR front hub (which is what you’re looking at on this page) can be converted to Boost 15mm x 110mm Thru axle with part# AXLEND17FABOOST available on the Parts>Hub Parts>Axle Parts page.
- Can I swap between the 9mm x 100mm QR axle, 12mm x 100mm axle, and the 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 Parts>Hub Parts>Axle Kits page. Instructions are in the Front Hub Assembly document, but it’s not a complicated procedure and does not require special tools.
| Axle you already have | Axle you want to change to | What you need to do |
| 9mm x 100 QR | 12mm x 100m Thru | Purchase the “12mm x 100mm Thru Axle for XMR”, part# KITF12THRU |
| 9mm x 100 QR | 15mm x 100mm Thru | Just pop out the QR plugs using a 2mm hex key inserted across the 2 little holes, and pull |
| 12mm x 100m Thru | 9mm x 100 QR | Purchase the “9mm x 100mm QR Axle for XMR & Mi5”, part# KITFQR |
| 12mm x 100m Thru | 15mm x 100mm Thru | Purchase the “15mm x 100mm Thru Axle for XMR”, part# KITF15THRU |
| 15mm x 100mm Thru | 9mm x 100 QR | Purchase the “9mm x 100mm QR Axle for XMR & Mi5”, part# KITFQR |
| 15mm x 100mm Thru | 12mm x 100m Thru | Purchase the “12mm x 100mm Thru Axle for XMR”, part# KITF12THRU |
- 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.
