XMR Front

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.

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 Axle Parts page.

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 Axle Kits page. Instructions are in the Front 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.
