Rims Aventon Abound - front wheel alignment?

[cprato]

Hi all, first post here. Been riding my Abound for a few months now and since I put it together, the front wheel rotor grinds slightly against the brake. I tried to make sure the brake was aligned, loosened the caliper, engaged the brake, re-tightened the caliper. Did not fix the issue. Took the wheel off and the brake pads, made sure those were aligned, still having the issue.

I realized that the wheel looks to be wobbling slightly when I spin it. So the rotor grinds on one side of the brake on every spin but just for a split second. Doesn't seem to impact much except a minor noise and probably slight impact to my range.

It does not look like the wheel is bent in anyway. Any thoughts on how to fix this? Thank you in advance!

Is the disc rotor be bent? Did you spin the front wheel and look at the disc rotor?

You have four things to do.
First check to make sure the front wheel is tight in the dropouts. I just had this happen to me and it was a simple task to tighten the qd on the front axle. While you have the front wheel off the ground grab it at two opposite points and try to twist the wheel back and forth. Grabbing the wheel at top and bottom works best. If you get ANY wiggle it is time to adjust or replace the wheel bearings.
The second is to check the runout on the rotor. You can do this with a fancy runout gauge or just clip a card to the fork and rotate the wheel and see if the distance between the card and the rotor changes. If it does you need to straighten or replace the rotor. ?
Then with the front wheel on the bike and off the ground use the same method to check the runout on the front wheel, both side to side and diameter. If the front wheel needs to be trued I suggest taking it to your local bike shop. This job is more of an art than a science and it is easy to spend many hours on it and do more harm than good.

Darn, I am having a similar issue with my rear tire appearing to wobble when it spins. I couldn't understand much of your tips, Atavar because I'm not familiar with the mechanic jargon.

One thing I did understand was messing with it could do more harm. Not too long ago, I was trying to true the spokes with pliers but I'm gonna stop.

This happened after I had a flat and was riding for a while without noticing until the tires air made it difficult to roll. I patched the tire but it still was leaking air. When I tried riding after patching it, I would feel the back wheel wobbling slightly especially when I turned. Not sure if it's the tube, the tire, and or the wheel
