Since you didn't specify year or crankset I'll do a data-dump. My old 1989 klein quantum had a pressed-in bottom bracket which my lbs recommended be replaced with a phil wood. I bought a newer frame instead. My '99 quantum pro (double) and my 2000 quantum (triple) are both sized for a 68 mm bottom bracket. 2001, 2002 and 2003 tech manuals, available as a pdf download from kleinbikes.com, all say 68 mm. Spindle length is 109.5 for a double and 118 for a triple. my 99 double needed a 1 mm spacer to get the chainline aligned properly.
