Today, wheels again (and so on).
Continuing from the other day. I built a rear wheel with an Open Pro disc rim.
The hub is an Alfine SG-S7001-11 32H
and I used a CX-RAY 6×6 JIS lacing pattern.
The left-right flange width difference is 3.15mm,
which is less than a fixed-gear track hub with single-threaded cones,
so there's no problem using same diameter and same count spokes on both sides.
I won't use spoke bracing. If I were to do it, I'd do both sides.
In other words, with this combination, the front wheel actually has a larger dish,
and spoke bracing is necessary—a very unusual result.
The dish difference is 3.15mm. In other words, if I move the left flange out another 3.15mm,
the hub would have zero dish.
This hub's flange thickness is 3.2mm, so if I move the flange out by about one flange thickness,
I can make it a zero-dish hub, and
at that point there doesn't seem to be any risk of the rotor or disc brake body
contacting the spokes, so
I wonder why it wasn't done this way.
Since the customer's preference was for CX-RAY, I went with CX-RAY.
The hole count specifications only come in 32H and 36H,
but if they did exist and were 24H or less, I might have used all Comp instead of all CX-RAY.
The hub's stated weight is 1665g,
but it varies with things like oiling with the dedicated oil,
and individual variation can explain the difference either way.
