Topic: Question for wheel lacing/truing experts

[edwardmorris]

So I just installed new bearings on the hubs and have new rims and spokes to lace them up. Before I did that, I just put the front hub on the truing stand to see how it was, and was surprised that it seems to spin totally out of whack. Haven't had time to check the rear hub yet, but since I got the rear brake surface cut at the machine shop, I'm guessing the rear one is fine because they would have complained if it wasn't true enough. Is this expected? I know wheel means everything from the hub to the tire, so do all wheels only need to be balanced as complete "wheels" or does everything from the hub outwards needs to be balanced and true individually?

Everything from the hub out it what youre "truing". The hub itself should really always spin straight, unless its damaged. I did mine with a dial indicator and a TON of patience.

I really like Oakys demo on how to do this, helped a lot

Thanks for these. I found this searching here a while back, very nice step by step with annotated pix

My concern is more with what to do with the hub, I spent hours sanding it and put in top of the line SKFs, would hate to have to abandon it now. Its out of whack a bit, but if the overall wheel can be balanced, then that's all the good news I need....

When I had my rear hub "arced" by RaceTech they required that the rear wheel be finished, laced up and trued, before they would cut the braking surface. The act of truing the wheel will distort the hub. Cutting the hub before truing may have been wasted effort.

It would then take a fairly large machine to hold the entire wheel (sans tire).

As to the question of balanceing, its the whole wheel including the tire, that gets balanced.
