Gross. This reminds me of the 2006ish era when companies hadn't quite figured out the really good heat treating techniques people tried to save weight with $80 titanium stem bolts and holes drilled in frames. What I think is dumb is that folding tires (which I thought were a good effective way to save a lot of weight) are basically extinct now because people thought they're were too expensive, but here we are re-introducing a dumb, fragile part that will save like 2 ounces.
