I think this came from a non-series Shimano crank, but it will work with several crank arm model's. This is for an octalink v2 interface bb with spindle length of 113mm and bottom bracket width 73mm. I'm listing this as used, but it was a takeoff from set of cranks I swapped over several years ago brand new trek hard tail. It also includes fixing bolts, which don't typically come with the bottom bracket, but I kept them on here for whatever reason.
