Hi, just got a pair of China wheels and as I was checking their trueness I realised that I have no idea how true they should be. Can you take a look at my videos below and estimate if it's bad or OK.

What do you think?

stick it in a truing jig and observe that way. better still one with dial guages and measure. Wobble can often look worse than it actually is when just spinning the wheel.

bm0p700f, I'm guessing you didn't click on the video links.

Doesn't look very good IMO.

You should take off the tires before checking the wheels though.
Also very important, the spokes tension should be even.

Just clicked on the 1st video, the tire isn't seated properly or has a hop, can be seen if you look at the sidewall near the brake track.

I've seen very expensive wheels (new) worse than this.
Bikes:

Ax Lightness Vial EVO Race (2019.01.03)
Open *UP* (2016.04.14)
Paduano Racing Fidia (kind of shelved)


Ex bike; Vial EVO D, Vial EVO Ultra, Scott Foil, Paduano ti bike.

I've seen way cheaper and perfectly true out from the box... . Those are not. Should see someone who will equalize tension and true it.

I can be wrong, and have plenty of examples for that ;)

Good observation. The rim may not be out of true radially, as the tire is not centered correctly.

I made the mistake myself not to have my cheap carbons trued up first, then mount a tire. Well next time.
