This is on my new Marin Argenta road frame app. 2002 model. I want to be sure of the correct bottom bracket dimensions before I purchase one. Thanks!

It's almost a certain that the bottom bracket shell is 68 mm and English threaded. The required spindle length and configuration (ISO or JIS square taper, Octalink, ISIS) depend on the crank you have. The spindle is measured end-to-end and is often engraved on the existing spindle.
