Happy Holidays!
I don't know, the schematic drawing on the linked page makes it pretty clear how they measure the 69mm. Still, 69mm is pretty short already!That said, getting a full reimbursement for a return on ali usually isn't a problem for me...just return it?
I mean it's drawn pretty clearly how it's measured, not their fault you didn't look at the description.
Hmm interesting that you interpret the drawing like that. In my opinion the 69mm dimension is between two lines neither of which are the centerline of the bar end (which is drawn and shown for the back sweep angle measurement).
You seem to want us to side with your interpretation rather than offer our impression based on the ali page. We dont have the bars and can't check ourselves, so that's all we can go on. Best to just return it! Fwiw i find straight bars with around 80mm reach to be the ideal anyways. Good luck with a substitute!
