Another wheel day (and so on).
Built the front wheel for Nomu Lab Wheel #4.
Reife hub, 20H, CX Sprint reverse two-cross radial laced
with red aluminum nipples.
This wheel was supposed to be built with green nipples,
but a customer came by today and we switched to red nipples at the last minute.
That was close. This wheel was one of my next build candidates,
so there was a real possibility I could have built it with green nipples yesterday.
The tire is a Continental Grand Prix 4000 S II (box says 4000 S2)
tubular tire.
The customer wants it stretched by tension without rim cement or tubular tape,
so after mounting I pumped it to 11 psi (tire's limit is 12 psi).
This tire is one of three Continental tubular models at the same price point
(the other two are Competition and Podium TT).
The tread pattern is the same as the Grand Prix 4000 clincher, but
otherwise it doesn't really have Grand Prix 4000 characteristics.
For one thing, the compound is completely different—
it has a stickier feel (in a good way), extremely high cornering limit,
and short sidewall height, so the overall wheel diameter including the tire
is noticeably smaller.
On the flip side, it doesn't have the exceptional durability
that the clincher model had.
The tire construction is quite unusual, even by tubular standards,
with the seam on the outer edge (under the tread),
so there's no seam bulge on the base tape side.
It's similar to TUFO tires, which have no seam at all.
When mounted on the rim without air, it has a pretty flat profile.
