Another day of wheel building (etc.).
I built a rear wheel using Ambrosio RV30 rims.
This is the companion to the front wheel with RV26 rims I built the other day. The numbers in the model name indicate rim height,
and the rim width is 22mm external width in both cases.
R-FORCE large flange hub 32H, semi-comp two-to-one spoke pattern
with gold aluminum nipples. I'll do the truing later,
but the deformation amount of the spokes on the left and right sides is extremely similar.
This isn't so much because the left-right different diameter/different count spoke pattern is working, but rather
the offset rim design and
the narrow flange width are the bigger factors.
This hub has a list price including tax of 19,200 yen for the front and 28,300 yen for the rear.
This is according to the brand's website, but whether the consumption tax is 8% or 10%,
the pre-tax list price doesn't come out to a clean number.
However, since a five-spoke front wheel is listed at 113,400 yen and
a road disc brake rear wheel at 162,000 yen,
these appear to be prices from when the tax rate was 8%.
The RV30 rim this time around is an offset rim,
but there isn't a non-offset version available.
Also, the RV26 rim doesn't come in an offset specification.
According to the manufacturer's website,
the hole count for the RV26 is listed as "16/…/32H",
which I believe means they offer sizes from 16H to 32H
in 4-hole increments.
Most likely there's no 18H version.
If there were a 22H version, it could be used for repairs on Neutron front wheels.
If there were a 26H version, it could be used for repairs on Helium front wheels.
If there were a 21H version, it could be used for repairs on original Racing 3 rear wheels,
but since this rim has spoke offset, to make it compatible with Racing 3
it would need to have alternating right-left-right hole offset or no offset at all.
The RV30 is a rim brake-compatible rim, but because it's an offset rim,
if you're building a wheel for rim brakes,
it can only be used on the rear.
There's also an RD30 rim,
which is disc brake only, so like DT's RR411db,
it comes only in offset rim specification.
The hole count for both RV30 and RD30 is
"24/…/32H".
Why not just write 24/28/32H? Is there some issue with that?
