what caramba cranks? Kooka imho were made of cheese. Caramba double barrels were also prone to failure based on threads ive read. I have a nos set of caramba sidewinder cranks which look solid. I had another set which were used and seemed solid.
The Double Barrels were inconsistent from what I read. Drilling those long bores along the length didn't always go well and they ended up thinner than planned in areas.
