Hello,

I am currently building up a new 585 frame, and is curious to know if the Bottom Bracket needs to be raced/tapped prior to BB installation?

In general, I know that BB racing is common practice, but does the 585 need the race?

TIA

do yourself a favor and have the threads chased.

Mine were way f'd up when i got it.

mine were fine...

The only thing I did was to carefully remove the paint from the right face. I use a large file and carefully massage the surface, just enough to expose the aluminum. My BB threads were fine, the cups both screwed in with little effort.
