Cruisin' on my Bluebird
Had this in a drawer for a long time and finally decided to try and figure out what it is for. One side says "Japan BC 34.6" and other side says "Shimano 32 (Dura-Ace)". Both sides are threaded and I assume one side is 32 mm in diameter and the other 34.6 mm. The center piece which looks like it should be used to force something out (or in?) can be screwed in from either direction. Hope someone can tell what it is used for. Thanks.
