This frame is a pretty unique case for sobs. Unlike most of the frames this one uses the legacy head tube with the thick support only being on the bottom of the head tube rather than the one that has the supports on both the top and bottom. Another curious thing about this frame is the top tube measures 20.75 center to center rather than the 20.5 that you will usually find on sobs. The serial number features uneven hand stamped numbers. The font of the numbers is different from from the font found on hand stamped kastan made frames, and the sobs that were made overseas have perfectly straight machine stamped serial numbers. Speaking to one of the guys who works at dk, I found out that MAAS did one or two batches of the sob. That leads me to believe that this frame was made along side the early T1 barcodes. Pretty neat!
