The one shown in the video is a quill type with cone wedge.
I don't understand the advantage of the Innicycle solution over a standard threaded-to-threadless adapter; is there one?
Also, people keep mentioning that there's a weight reduction, but I don't see that either. 1-1/8 inch stems seem pretty partsy and clunky to me, so how are they lighter? Thinner walls to go along with the thicker cross-section?

The headset and quill stems are elegant looking components on any classic bikes. Whereas a 1 1/8" stem is just huge and clumsy looking. Also- why do bikes even need 1 1/8" steerer tubes? There are a fair number of motorcycles that don't even have steering stems that big.

Your aesthetic preferences aside, the fact remains that there is currently a vastly wider selection of 31.8 handlebars. Threadless stems are also widely available and most are much cheaper than the Nitto UI, which is particularly helpful for dialing in fit.
