Wheel issue

I have ukai alloy wheels in 700c on my Fuji America. I think the rear wheel has a Tiny dent on the rim because I get a slight tick on every wheel rotation. There is nothing visible to the eye. Any thoughts on how to fix this?

You should be able to feel a dent in the rim's brake surface. What do you mean by "tick"? Is that a sound you hear? Is the brake surface touching a brake pad? If it is a sound, and the rim isn't brushing a pad, the sound is likely coming from the hub.

I don't know about your wheels, I've had the seam on wheels give a tick. I took a fine sandpaper to the the area in question and lightly took it down. I think my rims were Mavic MA2, they have been great ever since.

It’s not the brake. Wheel spins fine without touching pad. When riding it almost feels like a slight bump after each rotation of the wheel.

Bpor3248 Bump or tick? Feeling or sound?. Bunp might be a "flat" spot in the rim or a bulge in the tire. A tick might me bearings in the hub. Be sure it is every rotation of the wheel. Make an effort to determine if it is in a fixed spot in the rotation or not. I understand the level of difficulty if weight on the bike is needed.

More of a bump each rotation. New tire did not fix the problem. Probably a dent in the rim but I can’t find it.

Try spinning the wheel in place looking at the rim and the brake pad that will show you if you have some hop in the rotation.

Dent, tick, or bump?

A "tiny dent" generally would not be detected while riding unless it's brushing the pad. How would it?

A "tick" in the rear wheel is generally a word used for a sound heard from either the freewheel or hub.

A "bump" is usually felt from uneven road surface. Even a hop in the rim won't be felt as a "bump."

We could go around and around on this all day. You're in the best position to narrow down the issue. Have you rebuilt the hub? Are all the spokes evenly tensioned on each side?

If it is a flat spot on the rim, any recommendations on how to fix that? Or is the rim toast?

If you can find said flat spot, you can loosen the spokes under it. Loosen both sides, little by little, until it comes out. Then you'll have to re-true the wheel. If you have a truing stand, or a way to have it at eye level, it becomes so much easier to do.

Are you sure that the tire is properly and evenly seated all the way around and on both sides? An improperly seated tire will feel like a bump every time around (had this problem super pronounced on my Jamaica motorcycle). So...

Take a close look at where the rim meets the tire when inflated. Look at the relationship and see if the line, closest to the rim, is evenly spaced. If not, that will most likely be the problem and easy to fix.

Here the embossed line is just under COMPAS and should be even all the way around both sides...


Here, the line is a lighter color, than the sidewall, but still needs to be even...

Spokes rubbing where they cross and when they enter the rim can also be a source of periodic "ticking".

Wheel issue

I have decided to replace the ukai 700c rims on my Fuji America. I was looking at the Sun CR18 622 rims. Any thoughts on these rims? I was hoping to go with a thicker tire than the 28c I had on the Ukais. How wide a tire can I use?

Those rims are quite versatile and could support any width 700C tire that fits within your frame and brakes.
