2″ Cup Bottom Bracket Set,One-Piece Bottom Bracket Cup Set Bearings Included,Silver

Good fit for eighties Sears free spirit.I can’t tell you the tpi wether 24 or 28 as it’s not specced.The threaded bearing cones fit which was a huge relief. Pay attention, the right and left bearing cones have different internal diameters. This is how the single crank is. The right crank side for the bearing cone is larger than the left side. So don’t be discouraged if you grab one and it appears to big!! That’s the right side one.
