Identify these rims off a Klein Stage Comp

Need the ERD for rebuild - current spokes are too long.

Silver, has sticker that says KAZ Welding Technology. Other stickers
missing. Semi-aero profile (more like CXP's than OP's). I think they
are Matrix ISO CII's but cannot confirm.

Can you?

TIA

Two spokes, two nipples, and a ruler will tell you the ERD.

Assume I am an idiot (perhaps not far off) and explain the methodology
for doing as you suggest.

No, but it is simple.

Put a spoke in each of two diametrically opposite holes; thread a nipple
onto each, pull them taught.

Measure the distance between the ends of the nipples closest to the centre.
Call this "A"

Measure one nipple. Call this "B"

ERD = A + 2*B

Repeat for some small number of opposite holes, just in case your rim is
slightly out-of-round.

It is simple. I keep a couple of spokes with rusted on nipples and the
elbows cut off, but that's not required.

Put a spoke in each of two diametrically opposite holes; thread a nipple
onto each until the spoke is flush with the end of the nipple, pull them
taut.

Measure the distance between the inside curve of the elbows at the
centre. Call this "A". If your spokes overlap then the value of A is
negative.

Measure the length of one spoke with a nipple threaded on flush as
before. Bottom of head of spoke nipple to inside of elbow. Call this "B".

ERD = A + 2*B

Repeat for some small number of opposite holes, just in case your rim
is slightly out-of-round. I hadn't thought of this. Good idea.

Put them into two holes on opposite sides of the rim, bring the ends
together (without forcing the rim into an egg shape), measure how far
apart they are, then measure the length of each spoke from wherever you
just measured to the part of the nipple that sits on the spoke hole, and
plug those three numbers into google calculator. Presto.

Do it twice at right angles to each other if you thin the rim might be
slightly out of round.
