Product Details

As with all our hubs, the the XMR+ (Cross Mountain Road Boost) 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.

The XMR+ is perfect for Boost spaced mountain and gravel bikes because of their low weight and clean, minimalist look, as well as their robust and durable design.  Designed around the 6 bolt disc rotor standard, the XMR+ rotates on two Enduro brand bearings, and are made here in our Petaluma, Ca. shop.  They are available in four spoke drillings seven colors, and two axle configurations.

FAQ

• Which is better, the XMR+ 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+.  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 12mm x 100 or 15mm x 100mm Thru axle?
  • Yes, but that would be a different model called the “XMR” (not Boost)
• Can I convert this hub to a 12mm x 100 or 15mm x 100mm Thru axle?
  • No.  The shell is too wide.
• Can I swap between the 12mm x 110mm axle and the 15mm x 110mm Thru axle?  And is that and difficult?
  • You can swap but you need to purchase a new axle kit.  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.

• 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.
