88mm

Today it's wheels again (and so on).

Built the rear wheel for a fixed gear with
an 88mm carbon tubular rim.

Going back in time a bit to when I had just the rim—
there were some odd whitish spots on it.
I tried various things hoping to clean it up nicely,
but no luck.

The adhesive residue from peeling off stickers
came off cleanly though.

Fixed gear hub with both sides fixed, 24H
fully CX Sprint spokes, laced Italian style.
I'll tension the spokes later.

Since this is purely for racing use and there's no need to install a freewheel on the left side,
I was told it was fine to lace it Italian style,
so that's what I did.

The reason I went with a 6-cross lacing pattern
wasn't to match the spoke angle of a velodrome's 36H 8-cross build—
it was because the rim height was too tall, and with 4-cross lacing,
I'd only have round-section plain spokes as an option.
With 6-cross, though, I could just barely use CX Sprint spokes
that can be cut down to 240mm.
Using aero spokes was the customer's request.

That said, the spoke length is actually a bit shorter than 240mm—
it's seriously just barely fits.
In the photos above, the 14-gauge plain section
peeks out slightly from the nipple,
but in other spots the flat section starts right where the nipple ends.
The nipples are DT Swiss 12mm black aluminum—
the black color was the customer's preference—but
if they'd been 14mm nipples instead,
the nipple would've dug completely into the flat section
and I wouldn't have been able to build the wheel at all.
