Another problem with ride wright
So last week I got my new wheels on but could to take it for a ride yesterday I take it out and as soon as I hit 40 mph the front end started to shake I brought it back home put it on the jack and looked at the front it seems like the rotor has about 1/8 of wobble to it and the rim has about 1/4 inch of wobble. I put the front end back together per the manual and how I have always done it. I am not running a front fender because it's at paint the bike is not lowered in the front. Any other ideas on what could b causing this??

There is an important clue in your statement that the brake rotor has 1/8" of wobble and the rim has double that at 1/4", about the percent difference you'd expect given the relative radii of th rotor versus rim.
I interpret this to mean that the problem is that the entire wheel assembly (hub, spokes, brake rotor, rim) is wobbling as an assembly. This suggest that the problem is NOT inadequate truing of the wheel, but rather a looseness between the entire wheel assembly and the axle.
This leads me to ask:
- Is the axle the correct diameter for this combination of wheel and bike? I ask because you said this is a "brand new rim that costs me a ton of money ". Therefore Iw ould check:
Is this perhaps a metric axle that LOOKS like the right diameter but is actually too small since its exact diameter in mm is smaller than the correct axle in inches (SAE) would be?
Or, if you are using your old axle, is this a wheel built to metric dimensions versus SAE dimensions?
Or, are you resuing old bearings that are too worn? Or, new bearings that are a metric vs SAE or SAE vs metric mismatch to the axle and wheel?
