it looks like super duralumin. did she say she actually put those decals on?
someone asked about the alloy duralumin cranks awhile back... i dont recall if anyone had any info
She did not say that she put them on there, it is a new yst bottom bracket, she got this stuff in 1989 when she bought the remaining stock of nos parts from Redline when they sold out to Seattle Bike Supply. The decals have been on them for a long time but they are the same decals you find on redline frames that say redline all chromoly.
I know this is a real old post, but did anyone find any info over time.I know one thing that is being mistaken in all this, CW cranks that had the 1/2" pedal bosses used a standard square taper (not larger Anlun) BB. I started a post over on the museum, here is the link:
