Aren't these just copper pipe fittings? Like to go from a smaller to larger pipe size? I could get like 10 of these at Lowe's for a buck. They won't last long at all if you're not using barends, either, cuz they're copper. It'll just dent and bend and get ruined and possibly stuck in your bars.
if you are going to talk to companies about it you might want to get a patient on them
