Servicing cups and cones

How often should I service my cup and cone bearings please, Time or miles is fine,commuting really adds the mileage.

It's as much related to the road conditions and weather as miles and time.

It rains a lot around here and I used to service them once a year. But I was splitting my commute riding between about 4 bikes just because I enjoyed them all for their differences. So if I were riding ONLY one bike I'd likely do it twice a year. Once just before the sloppy season(s) and once at the beginning of the good weather times. This would be based on my roughly 2500kms a year distance that I rode while working. After doing this for a year I'd re-evaluate based on what I found inside the bearings and adjust accordingly based on what the contamination level was like.

Now that I'm retired I am free to pick my riding times so I can avoid the worst of the weather and still get in a ride by waiting for mid day on even the worst days where it typically stops raining and the roads and paths at least get semi dry. Under those conditions I won't need to service them as often.

Texas is a dry place... I serviced my hubs several times this winter, until i swapped for sealed bearing. Once a year is a minimum, you should do it as soon as you feel your hub isn't perfectly smooth anymore (hold the axle in your hands and spin the wheel). I'd check that every month or so on a commuter, more often if the weather is really bad.

I would not wait till it's rough - cones might be damaged at that point and correctly broken in cones are smoother than when new. I would check every few months on a commuter even if smooth. Loosen one side, unscrew the cone a bit and look for signs of grease contamination on both sides. If starting to look bad overhaul it. Don't wait beyond a year.

... UNLESS you're riding a lot in wet or dirty (or, especially sandy) conditions. If you're riding mostly on dry, clean roads, with an occasional rainy ride, then no worries--once a year. It all depends.
