Another wheel day (and so on).

Built a wheel with a Chris King pink anodized hub and
an Open Pro rim.

Front wheel: Classic Low Flange hub 32H in black, competition lacing, radial spoke pattern.
Chris King makes a hub called "Classic" that doesn't quite reach large flange proportions,
and this "Classic Low Flange" is the small flange version of that.
The flange diameter and width are so close to the R45 front hub
that you might say they're basically the same,
but the hub body itself is thicker here.
While Classic and Classic Low Flange come in 28, 32, and 36H configurations,
the R45 comes in 24, 28, and 32H (plus 20H for front only).

Got the rear wheel built too.

Classic Low Flange hub 32H in black champion/competition, 48-spoke lacing.
I'll do the dishing later.
The Classic rear hub has flange hole spacing of 53.0mm on both sides,
but with the Classic Low Flange rear hub,
the freehub side stays at 53.0mm while the non-freehub side becomes 44.0mm.
So really, only the non-freehub side becomes small flange,
making it more of a hi-lo flange setup than a pure small flange design.
I'm listing the flange diameter to one decimal place because
that's how Chris King's specs are written,
and some hubs do have non-zero values in the last digit.
By the way, my actual measured values are also 53.0mm and 44.0mm,
and Chris King calls this flange hole spacing measurement
Flange Diameter.
As I mentioned before, when you say "flange diameter" or "flange dimension" normally,
you're referring to the flange hole spacing, not
the outer diameter of the flange itself. I don't think that ever comes up.
On the non-freehub side of the Classic Low Flange hub,
the flange with 44.0mm hole spacing
has an outer diameter I measured at 52.3mm,
but I can't think of any useful application for that measurement.
In Shimano's catalog, for example, the rear hub of their XTR
FH-M9000, on the non-freehub side,
lists "spoke hole pitch diameter" as 44mm and "flange diameter" as 52.8mm.
The measurement I call "flange diameter" and Chris King calls "Flange Diameter"
is what Shimano calls "spoke hole pitch diameter," not flange diameter.
