My current setup is as follows:
401 full wrap arms on what seems to be a new spindle (generic, proline or double pinch flight) with a new profile sealed BB. The spindle is not threaded like the early 401 dimpled spindles. I found out this when I bought new 401 bolts that didnt fit the current spindle, they were too big. The current bolts are alot smaller.
My question:
Can I run the current profile sealed BB on an old 401 dimpled threaded spindle?
thanks
