DIY true a wheel (lemmy.world)

I had some wheel made but when they rotate they come in contact with the disc break pads (slightly).

The bikeshop that built them will take another month to look at this, as they are fully booked, and I dont want to pay 35+ on another bikeshop..

Is it doable to DIY this with a spoke key and using the fork as a stand?

(I think it would be a useful skill to learn as it will make me less dependent on bikeshops)

Truing the wheel has no effect on your brake rotor rubbing the pads. You have a bent dics. You can straighten it using an adjustable wrench. Just make sure it's clean so that you don't contaminate the brakes. If it's rubbing all the time and not just at certain point then your calipers might be out of alignment or your wheel is not seated properly

If there is a side wobble in the wheel and the discs are attached to the wheel, wouldnt that make the disc wobble? And if the disc wobbles, couldnt that make it rub to thr break pad?

(Also he discs are brand new and not look bend at all but not sureidf i can tell just by looking at it)

No, the disc is attached to the wheel hub. Wobble on the rim has no effect on the brakes. If it was a road bike with rim brakes then it would but not with disc brakes.

If you rotate the wheel and look thru the brake caliper you can see which part of the disc rubs and which side. Put adjustable wrench on that part and bend it to the opposite direction and check again. It's pretty easy to straighten. I've had that happen on relatively new discs as well.

Here's a good tutorial
