Another day with wheels (and so on).
Here's an ENVE 25 rim, now known as the Classic 25.
The 45 and 65 come in two types: a light "1" and a durable "2"
and the rim markings are printed as "1.45" and so on,
※A euphemism for "heavy"
The 25 doesn't have a "2," so
you won't see a marking like "1.25."
The "20" in "25-20" refers to the number of rim holes.
The serial numbers are 7 digits, ranging from 1.42 to 1.44 million.
From EDGE through ENVE, the 25 rim's published weight has evolved:
195g → 215g → 250g,
but at the very end it became 274g, and based on the serial number,
this is the final version of this rim. In other words, it's on the heavier end for this particular model.
It's under the published spec, so it's actually a lighter example among its generation.
I built the front wheel with the 264g one.
Leaf hub 20H, black CX-RAY reverse Nupoke radial lacing.
Even this is lighter than a SES 3.4 front WO rim alone.
These are my personal rims, so I don't mind showing their serial numbers.
The 45 from the 5-digit era doesn't have the "1.45" marking, so
there might not have been a "2" rim back then.
The actual measured weights from the images are 194g, 291g, and 308g,
and 291g for a 5-digit 45 is quite heavy for an individual example.
The average is probably around 278g.
This is also my personal rim, but
it has the original EDGE label, and
hard to make out, but it's a 5-digit number in the 90,000s, with a rim cement bed,
and here's the actual measured weight.
The hub is 24H, so it's a 24H rim,
but if it were 20H instead, the spokes would be minus 18.8g,
and the nipples would be minus about 1.3g,
so it would be about 20g lighter overall.
