Tange LN-3922 JIS square taper bottom bracket size 68x113. High quality all metal construction, made in Japan.
I ordered this to replace a worn out Shimano UN26 bottom bracket and wanted something higher quality than the Shimano UN300 series. I did install it briefly, but realized it was not the correct size and ended up buying a different size (same Tange LN-3922) for the new crankset I installed.
