    80kgf tension rear wheel

    I have a rear wheel I measured driveside 80kgf tension (fusion rim, 28h) with Park TM1 which hasn't gotten out of true. (From Handspun.) Should I tighten tension to 110- 120? IOW, what is the minimum DS tension?

    That does seem a bit low for the DS tension. Have you tried riding it yet? Does it feel a bit spongy?

    You do not need to increase the tension, but the wheel will be more reliable in the long term if the tension is brought up to 110-120 kgf on the drive side. The non-drive side spokes probably have a very low tension now which increases the chances of fatigue failures. I assume the wheel came with such low tension since it is much faster to build/true a wheel with a lower tension.

    You should not feel any ride quality differences after the tension is brought up, and the time you spend taking care of it now will save you time in the future.

    Yep... that rim can take high tension. Be sure to check spoke twist and stress-relieve also.
