Wheel Run-Out

[monty_jon]

What’s an acceptable amount of wheel rim run-out?  

 

I have a few workshop manuals and they all recommend checking run out when tightening spokes but none give actual tolerances!

In which direction?

To the side or on height?

A sidewise run out of 1mm is still Ok, while 3mm is too much.

A run out to height here also 1mm is OK, tires have already a run out of 1 - 2mm, a good workshop will mount the tire so that the run out of rim and tire will be compensated to each other.

Anyway as it is a trials bike I guess there are not so high standards as you can't ride very fast as with a road bike.

So a rum out of 2-3mm might still acceptable in both directions. I personal don't like it and gave the wheels of my old bikes to a professional "Radspannerei" that trued them, a small amount of bucks and as they too check the tension of the spokes worth to spend,(10 € per wheel). I gave them just the wheels and axles to save money.

If you ride a bit then id agree with scrauber, a bit here or there doesnt make any difference.

I try to get my wheels trued once a year and that keeps them good enough.

unless you have a proper set up for truing its a tricky job anyway.

I do <2mm for radial and lateral. Check when I change the tyre and check spoke torque every few rides. 

 

2mm run out with trials tyres????

id love for my rims to be that good.

Ive seen rims that are welded 4mm out.
