• I'm just making my first foray into wheelbuilding. I'm bulk building 20" wheels for my pedalcar team. All side mount so thankfully no need for dishing and I've got the hang of lacing and getting started on tensioning and truing.

    However, without an experienced person present to guide me through the process I'm a little unsure on how well I'm doing on those final stages to get the wheel finished. I suspect that the manual drilling on the purpose built hubs along with the budget rims is affecting the final outcome. However I can't seem to knock out the last little wobble on vertical truing. Horizontal truing is pretty damn close.

    Having only ever trued 700c wheels before, I'm just wondering whether it would be normal for 20" to be a bit harder to work with?
    Also, while the spokes are under tension, there is a bit of flex in them when I squeeze a crossed pair. I know I won't completely remove that but should I be tightening them up so the flex is very minimal? Or is a bit of flex OK as long as the tension all round is even?

    I'm just cautious of overdoing it.

  • I could imagine that working with a smaller circle, the same amount of variance in tension would produce a more noticeable hop. Have also read that anything < 1/2 mm isn't worth worrying about, and I'd guess that holds even more true for something using 4 wheels as opposed to two
