Apeks XTX lever height

[buddhasummer]

You'll need at least 2 different tools to cover all those models. I'm not sure about the TX.

So do you mean that you have the AT20f lever height tool but prefer not to use it? I am asking to know if I should buy the tool for XTX, TX & ATX

Yes. I used it once or twice only. That is for the factory spec setting but you might want to adjust it. That is my starting point (flush with rim) and adjust it to my preference.
