Maintenance, Bearing, and Wheelbuilding

Maintenance

Yama hubs use a ratchet mechanism, and as such require very little maintenance.

Just like with all hubs, we recommend against high-pressure washing around the endcaps either side of your hubs. 

Cleaning and re-greasing the ratchets + freehub comprises the recommended routine maintenance. 

To do this, or if you wish to make the freehub quieter, Dumonde Tech Pro X Freehub Grease is recommended. Thinly apply between ratchets.
