Wheels again today (and so on...).
A customer brought in a rim called the Excellent LT28 from the Fire Eye brand.
With a stated weight of 585g, this is a rim that's intentionally made heavier to prioritize strength.
Jumping ahead in the timeline—this is an image after the wheel was built.
After the FIRE EYE marking,
there's simply 28, which indicates the rim's outer width.
With the Excellent LT30 rim,
that number would be marked as 30 instead.
The rim diameter is 26" HE, which is the old MTB size, but
aside from this, there's also the Excellent rim available in
27.5" (650B) and 29" (700C) with finely graduated width variations in the lineup.
The precise outer rim width is not 28mm but
27.8mm.
The inner rim width is 21.0mm,
which is actually narrower than today's wide road rims,
and the bead hook has substantial thickness.
The valve hole is Presta (or Schrader) size.
I'm building it with a Shimano Alfine 11-speed internal hub.
Just the rim and hub together
exceed this scale's 2000g capacity,
so I can't weigh the complete wheel on this scale.
It's built.
SG-S7001-11 hub, 32H,
all Strong Rokuroku JIS lacing, no disc brakes.
Even with the center-lock rotor mount on the left side, this hub still has
a small amount of dish,
but not enough to warrant asymmetric or different-gauge lacing,
so I used symmetric same-gauge lacing throughout.
The spokes are Sapim Strong.
For a few centimeters from the elbow, they're 13g (2.3mm),
then from there they're 14g (2.0mm) single-butted,
and the nipples use 14g.
Since the customer requested strength above all else,
I chose these spokes.
The spoke relative weight metric I advocate
uses 14g plain spokes
(strictly speaking, DT Champion 14g)
as the 100% baseline,
so Strong spokes, which have thicker sections,
naturally rate above 100% in my metric.
The stated weight for 260mm × 64 spokes is 446g,
so calculating from that:
446÷64÷260÷0.0257 = 1.04291..., which gives
approximately 104%, but in reality it's closer to 106%.
