Expect the unexpected….lol
Ok…GeX installed…and had also kind of interesting issue.
I did install a 12sp Shimano 710 cassette…which seemed to be okish on a normal 10/11/12 speed road freehub.
No spacer…
Without chain, derailleur was physical unable to move lower than 2. sprocket…
Now…install chain.…then, check limit screw to be no factor…then go to iniatial setup.
Somehow for me the adjustment of the 1. sprocket did not work.
By accident I shifted up to 12th sprocket and started initial setup again…now the derailleur thought
my 12th would be my 1st….(there is always a pop up to confirm if you are sure….lol)
Anyhow…I was able to fine tune this „1st“ sprocket all the way down to its correct position.
So…if you still struggle…you my try this.
Shift whatever speed …. 3rd or 4th…now start initial setup…confirm this to be 1st gear and then
finetune it all the way down to its realworld position!
That worked for me…
From there all gears worked correctly!
And I can confirm the short cage rear GeX weight is 403g
