Short answer: no, not with the parts either company sells. A CYBEX seat unit will not mount to an UPPAbaby Vista frame without an adapter, and we are designing one.
Why it does not fit
The two brands' mounting interfaces differ in polarity, not only size. The halves that would need to meet are the same sex, so there is nothing to seat into. An adapter supplies the missing half — it is a designed part, not a shim.
You will need to pick upper or lower
The Vista has two mounting positions that use different size connectors. The lower one takes the smaller connector — it is where a RumbleSeat rides when the Vista is set up as a double.
So there is no single adapter that serves both. When ours ships it will come in an upper version and a lower version, and you pick the position you actually intend to use. Want both? You need both parts.
Which Vista years this covers
Vista V3, V2 and 2015–2019 share a mounting interface. 2014 and earlier do not and are not compatible — worth checking first if you bought the frame second-hand.
What we are doing about it
In design, against both parts in hand. Not shipping yet. This one carries a child, so it gets a slower and more careful path than a cargo bracket does. Tell the Fit Finder you want it and we will email you the day it ships.
