Playing around with ideas for a set of light weight wheels for my races with the most climbing.

Want aluminum rims and think my choices are basically:
Ambrosio Crono F20
Mavic Reflex
IRD Cadence
or buy a used set of American Classic 350's just for the rims.

Am I missing anything? Any favorites? These will be with White Industry hubs, 28 CXRays 2x, and I'm 140lbs/ 63.5 kg.

TIA,
Peter

Are you wanting clinchers or tubulars or does it matter one way or the other?

I ask this because your list has has both clinchers and tubies.

Doesn't really matter. Ideally they'd be clinchers (lower rolling resistance, more convenient) but since they will only be used for races it's not that big a deal.

Mavic or 7

I don't think you'd have to buy an AC350 wheelset really. I've been told rims can be sourced from Europe.

As to extend your list personally for clinchers I do find the Alex rims pretty interesting too.

Only problem is that most of the rims are very old. So they are very hard to find

Alex R3.1 370 grams- you can get them in the US.
AC350 365 grams- 80 euros each plus shipping from Germany.

I know which one I would buy

56 Euro for the AC rims if you order from the US.

That's minus the VAT I guess ???

Yes and with sales tax it's €65.

some more weights:
American Classic Magnesium - 300 gr!!
American Classic 350 - only 350 gr.
AC 420 - 420 gr

Is the Alex rim OK for the rear too, or is it a front only rim? And how do you find the breaking surface?

Also, I should have clarified that I'm only interested in rims that are currently in production.

Thanks for the suggestions! looking like the Alex R3.1, the Ambrosio, and the AC 350 are the finalists so far... Although, if the Mavic Reflex really only weighs 370, it would be considered as well- love the Mavic breaking surface.

I think the Alex 3.1 rims are for the front and the 3.2 are for the rear (offset) and weigh 420g.

You don't really have to have the offest rear specific rims for the rear. You could always just get the 3.1 and dish the spokes differently (just like any other rim). But bikemessenger could tell you that for sure as he is a wheel building guru.
