Unusual Suntour bottom bracket
I just obtained a Suntour bottom bracket that is a sealed unit which can be adjusted for chain line. The end "cups" have eight square notches with a diameter just under the thread diameter. The lock rings are separate from the cups. The chain line is adjusted by adjusting both cups to the left or right, then tightening the lockrings to secure them. I haven't been able to find any mention of this bracket anywhere on-line, and will probably have to make my own tool to adjust the cups. Has anyone else seen these before, or know where a tool to fit the cup patern may be obtained ??? I have the original box but there is no part number on the box or part itself. The lock ring is inscribed Suntour-II Photo attached
