Another day, another wheel (you know the drill).
Here's an ENVE 25 rim—what's now called the Classic 25.
The 45 and 65 come in two types: the light "1" and the robust (※) "2"
and the rim markings show things like "1.45",
※euphemism for "heavy"
The 25 doesn't have a "2" variant,
so it doesn't get marked "1.25".
The "20" in "25-20" refers to the spoke hole count.
The serial numbers are seven digits, running from 1.42 to 1.44 million.
From EDGE through ENVE, the 25 rim's claimed weight evolved as
195g → 215g → 250g,
but at the very end it hit 274g, and judging by the serial number
this is the final version. In other words, it's among the heaviest specimens of this rim.
It comes in under spec, so among this generation it's still a relatively light example.
I built the front wheel with the 264g one.
Reef hub, 20H, black CX-RAY outpoke radial lacing.
Even so, it's lighter than an SES 3.4 front WO rim alone.
These are my personal rims, so I'm fine showing their serial numbers.
The five-digit 45s don't carry a "1.45" marking,
so maybe there was no "2" variant back then.
Measured weights from the photos are 194g, 291g, and 308g respectively,
but 291g for a five-digit 45 is pretty heavy.
The average probably sits around 278g.
This is also mine, but
it's got the original EDGE label, and
hard to read, but it's got a five-digit serial in the 90k range and a rim cement bed.
Here's what it actually weighs.
The hub is 24H, so it's a 24H rim,
but if it had been 20H instead, you'd lose about 18.8g on spokes
and about 1.3g on nipples,
so it'd come in around 20g lighter overall.
