XMR Rear

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!

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).  Instructions are in the Front Hub Assembly and Rear Hub Assembly documents, but it’s not a complicated procedure and does not require special tools.  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.

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.

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

You can swap from one axle to the other, but you will need to purchase a new axle kit.  Those are 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.

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.

Use “Mothers Mag and Aluminum Polish” with a microfiber rag.  Start with heavy pressure and lighten up towards the end.

Unfortunately we do not offer those options.
