SR SAKAE CUSTOM BICYCLE 22.2 MM 5355 STEM 50 MM REACH 25.4 MM CLAMP 180 MM

From the best of my research these dimensions should be close. Please see my photos if you think my info is off Please let me know so I can correct the listing.  I wascnot super positive about the 180mm measurement - didn't know where to start/ stop measuring the long side. These are new with no packaging

They camebfrom an estate that had a huge amount of vintage BMX and bike parts.
