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.
