oldtired:
which  era  flight crank,  and what size is the bb on the frame ?

Bfellows:
401 full wrap flights with standard 51mm (?) US style BB.

oldtired:
from that info bb will be standard   U.S  one....... if the spindle is an un threaded one...

 however some  redlines had  different spindles , depending on the what years they're  from, which may affect the bb type you need


 check out this thread , covers a lot of redline gens ,and the bb that go with em,   if you're unsure when it lands post up a pic , you'll get a definite answer from someone then  :daumenhoch:
