Truing, Dishing (2:Rear) and spoke tension
This afternoon I trued and dished the real wheel of my bike. I began 3 p.m. after I was back from skiing training. It wasn't good to begin wheel tuning late in the afternoon, because it takes more than 3 hours to do all the processes.
Detaching the wheel, getting rid of the tire and tube to set on the truing stand, checking spoke tensions, truing, dishing, and set the tire on the wheel and the wheel on the bike again.
This time I used Park Tool spoke tension meter. I found that the tension of spokes are a little bit too strong, some of ones on the drive side were more than 150kgf, so at first I weakened the tension a bit first.
Then I trued and dished. Especially dishing was the problem. I found that the wheel is about 3-4 mm aligned to the non-drive side. The tensions of spokes there seemed too strong.
After truing and dishing finished, I checked some of the spokes again. Tensions weren't even even as to on one each side. Those of non-drive side was quite serious. Some measured 86kgf and others did less than 50kgf. This is probably because of relatively low precision of the rim, or rim has somehow been transformed from shocks from riding.
When I dealt with the front wheel on Sunday, I found no problem with hub, but this time I found the rear hub didn't rotate smoothly. Maybe, it needs overhaul some day later, so in order to prepare for this, I check for the documents for the components.
