New Wheels (Rims)

I just had a new excel rim and new spokes laced to the stock hub of my XR4. I just put it on the bike and, to my dismay, noticed that it hops at speed, like the rim is egg-shaped. (Not real bad, but noticable). I put it on a stand with the front wheel off of the ground, spun it, and the rim (not the tire) definitely has about a 1/2 inch up and down oval to it. None side to side, just up and down. Obviously, I'm going to take it back to the place I had it laced.

But before I do- I'm wondering if it could be the axle that is bent. When I dropped it off at the shop, I didn't leave the axle. The bike is well maintained but definitely has many hard miles on it. Has anyone ever heard of a bent front axle causing this problem? Could it be that my old rim was so tweaked that I just didn't notice it?

Your accumulated wisdom would be appreciated.

i doubt it's the axle...i've noticed these things...poor tire quality can lead to problems...tire not fully seated on the rim might be problemo...i just had an excel put on my front end and the shop laced it up with the wrong offset and the wheel was almost touching the right fork. make sure you check the rim itself for out of round. that will tell you what ya got involved. :)

Who did your wheel work?

The first step in wheel lacing is make sure it's round. Then tackle the side to side run out.

Take it back and demand the mechanic gets properly punished by the service manager. Only after blood is showing politely request they properly true your wheel.

1/2" of radial run out is just plain incompentance. Don't let anyone tell you that is within spec on a dirt bike.

Thanks for your help, I'm taking it back to the shop today.
