Anyone recognize this Sugino 75 BB

It is sort of different than ones I have seen.

Never installed.

jdawginsc which part you mean different? This is for the Sugino 75 crank. AFAIK, that crank should only be used with these Sugino 75 BBs.

Looks to me like the spindle and bolts are Sugino 75 but the cups are not. S75 cups have a different shape and are NJS-stamped. I have a spare DS cup if you’re looking for one.

Aha! That's why it looked different. So the part I was actually referring to was the crank bolts (honestly didn't think to look at the cups. Just assumed to be 75 (and now looking at them, it looks like the fixed cut is a bit off.))

So it is a Franken-bracket.

It came in a lot with some other part I wanted but thought it was cool nonetheless. I have no desire to search out Sugino 75 stuff! I would have to sell my children.

The Sugino 75 spindles and cranks use a proprietary taper that is not compatible with JIS or ISO cranks or spindles. Might be worth something on ebay or as trade for a standard spindle.
