After a week of not getting an answer from my lbs, it's time to sort it. Sure it don't take a week to not find out.
Apparently it used to be Jungle, but told by lbs that syncros are a rebadged DT Swiss product and they sell them, but warranty issues are sorted by Pace! Forks maybe, but not rims I would have thought.
Now we're "waiting to hear from Jungle".............
It's a DS28, 2" splits running out from about half the eyelets by the way.
