Bikes: '96 Litespeed Catalyst, '05 Litespeed Firenze, '06 Litespeed Tuscany, '20 Surly Midnight Special, All are 3x10. It is hilly around here!

AFAIK, the UN-72 series bottom brackets are out of production and you will have to find an NOS one if you can.

Otherwise, the UN-52 is the best commonly available and current production square taper cartridge bb Shimano still offers.
