    PF92 Bottom Bracket Shell Source?

    Does anyone know where I can get a PF92 bottom bracket shell, preferably in aluminum? Paragon has a few left in steel and Ti, but these are made undersized and they're being phased out anyway.

    I was making PF41/92 shells for years before Paragon started. They're easy enough to make but I've been buying the PMW since because they are nice.

    How are they being phased out? PF41 is the best system put there. I've heard nothing of this.

    My backup will be to make one on my FNC* benchtop Atlas. Just looking for the easy button since I'd have to order material anyway.

    *That's Feldy Numeric Controlled

    I mean phased out by Paragon, not the industry in general:

The outside diameter is 1-3/4" x 93.5 mm wide, providing 1.5 mm for facing after welding. The inside diameter is supplied .5 mm undersized to 40.5 mm (1.595"), and must be finished to size after fabrication by the frame builder. It is relieved in the center for weight reduction to 42 mm (1.653").

    DISCONTINUED STYLE, ALL SALES FINAL.

    Item sold individually.

    Someone ask Paragon to knock out the BB392EVO shells.

    For those scratching their head...it's a BB92 width shell that accepts PF30 bearings.
