Rear Wheel bearings

[Guitarplayer]

I've got an Invader 5 spoke rear wheel that is setup for a knucklehead drum brake/sprocket.  Was wondering if someone could point me in the right direction as to what wheel bearings to look for?  thanks.

The best bet is to go to a bearing supply and have them measure the wheel diameter and width of where the bearing goes, and have them match it to your axle.  Your axle is probably 3/4".  So many wheel manufacturers use different size bearings that it would be hard to give an exact size over the internet.  You might want to try sealed bearings too.

Your existing bearings should have a number etched into the races, and Bearing Supply houses can cross reference the number to get you an exact replacement. Sealed bearings are best, but use the outer lip seal if you can.
