SIM WORKS, introduced on their site, the "WENDY" stem has become a quiet hit.
While SIM WORKS stems have until now been the 31.8mm oversized series, this WENDY is a so-called road stem with a 26.0mm diameter.
It is a modified version of NITTO's UI-2 by SIM WORKS,
ordered to NITTO with CP plating (a finish that is practical for ease of painting and brings out the material texture of the steel) and an extension angle of 82°.
(Apology and correction:
The web shop listed it as 72°. The correct angle is 82°. We sincerely apologize for this.)
The 82° angle looks like
this.
Depending on factors like the frame's head angle, I think this is an angle that creates a sense of unity around the handlebars on steel road and fixed-gear bikes.
The regular UI-2 is 72°, so it has a slightly more downward tilt.
And the well-received black series is also available. 
Also added to the black series is the SIM WORKS JOHN-B BAR Black
a 31.8mm oversized, lightweight, and high-rigidity chromoly steel handlebar for track racing.
In the grand scheme of bicycles, chromoly is a material from a bygone era, but the suppleness of the material, the smartness that comes primarily from its slimness, and the warm texture of NITTO's handiwork are things that cannot be expressed by other materials like aluminum or carbon.
Black, for better or worse, is an existence that allows nothing else to come close. It also gives a tightened appearance, making it perfect for those who want to build a speedier-looking bike or for those who want a slim, simple aesthetic.
