Another wheel day (and so on).
A customer brought in a Sun Assault rim for me to work with.
This rim comes in silver, black, and gold, plus two camo patterns:
Camouflage and Winter Camo. Winter Camo features a white, grey, and black winter pattern,
so this one is the standard Camouflage color.
The silver, black, and gold versions have brake zone treatment on the rim sidewalls,
but the two camo colors are painted all the way to the rim sidewall.
Because of this, they're not really intended for rim brakes.
The hub is a Hope disc hub that the customer provided,
so rim brakes definitely won't be used.
The intended use is cyclocross.
Front wheel is built.
It's a 6-cross reverse Italian spoking pattern.
If we only considered wheel balance, the front wheel is reverse ochoko (offset hub),
so 4-cross or 8-cross spoking would work,
but that would make the rotor side a 4-cross pattern (closer to radial than tangent),
so I avoided that.
Per the customer's request: black spokes with gold nipples.
I don't solder black spokes since soldering isn't really feasible on them.
Steel can't be anodized, so the black color is technically paint.
I've even tried soldering black spokes by letting solder seep into the nipple seat,
but it didn't work out.
About the front hub—
the end caps come off easily.
Looking at how little clearance there is between the outer and inner bearing diameters (meaning a larger axle can fit through),
it appears this hub is designed to be converted to thru-axle with just a parts swap.
Rear wheel is built too.
Unless the customer specifies otherwise, I build disc brake hubs with
reverse Italian spoking on front and JIS pattern on rear,
so this is also JIS pattern.
The Assault is a low-profile rim, but the hub has fairly large flanges,
so the non-drive side only needed spokes within 306mm length for 8-cross.
However, the longest available length of DT black competition spokes is 300mm,
so I ended up with a 4-6 pattern: 4-cross drive side and 6-cross non-drive side.
When doing X spokes on one side and Y spokes on the other,
if X/2 and Y/2 are both even or both odd,
with standard hole offset rims (what I call "correct rims" on this blog),
the phase relationship between spokes and hub flange holes becomes left-pull Italian spoking or right-pull JIS pattern.
When X/2 and Y/2 have one odd and one even,
this relationship reverses—a trap specific to 4-6 patterns that
I completely forgot about.
I noticed it during the preliminary build, so I took it apart and redid it.
↑It's a 4-6 pattern, so even though it's JIS, it's left-pull.
Despite me saying things like "watch out for this" and "this'll be on the test,"
I started building it right-pull initially.
JIS with 4-6 spoking is pretty rare, so...
that's my excuse anyway.
