I have been having a debate with my riding mates about the lightest road wheels available to the general public (at general public prices). I know this topic would have been done before but any new updates? I have heard about Spada wheels from Italy (mentioned on an old WW list), but can't seem to find much about them. Any advice?

I think the AX Lightness 25mm rims with tune hubs and dt revolution spokes will give you one of the lightest wheels out there.

This too is light. Extralight Hyperclimb aka the "Moon Climber" @ 840g.

http://www.extralite.com/Products/hyperclimb%20E25.html

I have been riding this on my weenie build for about 6 months and unlike previous sub 900g pairs that I owned - the Tune Skyline-Reynolds KOM and LEW Pro VT-1, the Hyperclimb is stiff and incredibly smooth (albeit I opted for the ceramic bearings).

Eager to try AX-Lightness-Tune once the full suite of AX Alpha frame- Morphius crankset is out.

I have a set of Edge 25 with Sapim spokes and M5 front, Extralite Ultra hub rear that weigh 780g. They can be made lighter with Pilar Ti spokes, but that's about it for a set of wheels you can buy.
My set of AX Lightness SRT42 wheels with Sapim spokes and Tune Mig45/Mag160 hubs weigh 920g, which is very light for full aero wheels. These can be made lighter with different hubs and spokes, but for me there's no advantage since I have the Edge wheels already.
There's a few posts with AX Lightness SRT24 and Tune hubs--they aren't the lightest wheels, but still pretty light.

A set of Ax24mm on SX rear and M5 front with xtra spokes should be about 730grams, that's about as light as you can do with production parts and no tuning. The lightest non-standard parts build has been the 608gram set that we did for interbike last year. We'll be topping that this year and shaving about 15-20grams off that taking it down into the 580-590 gram range.

We also expect that there will be lots of production hubs coming out next year pushing the weights down further. I know of 4 different companies playing with different hub ideas. Most have been prototyped and are currently being testing.

Found a reference to the Italian made Spada wheels on Ebay.com.au and it appears they are available in Australia. They have a very light carbon tubular at 850g.

This is my first post and I signed up because of this old thread.
I like the Reynolds RZR 42 and the ax-lightness 42 but...I need UCI legal wheels and neither are.

Best I can tell of all the ax-lightness wheels ONLY the SRT24s are legal because they fall under the 2.5 cm depth so they don't have to be on the UCI list. The 42s are not on the UCI list. I'm posting so someone might correct me.

Anything UCI legal that approaches the performance of the ax-lightness SRT24?

I'm assuming then you are going to b eusing these in UCI races where they will be checking wheels?

There is the rub. Sometimes they do and sometimes they don't. This is for my U15 racer who will not be checked for 1.5 years (U17) but I want to buy something he can use at U17+. This year at US nationals one referee declared some TT bikes that junior riders flew out not to UCI spec and they had to use other bikes. I hope they enforce the rules they put us through all this pain to follow - or get rid of the rules.

No they are not. The team version is.

Looking forward to seeing and reading about those!

Can you show me please. This is the list I am looking at. http://www.uci.ch/Modules/BUILTIN/getOb ... id=NDkyNTc

My son has used both wheels this year and they are different in feel and weight.

The RZR 46 is listed as 968g/set
The RZR 46 Team listed 1185g/set is the only 46 listed as UCI approved
From Reynolds:
The RZR 46 Team, exclusively designed for athletes competing in UCI-sanctioned events, utilizes the same technology as the RZR 46 with the addition of Kevlar reinforced rims and spokes to meet the guidelines of the UCI (Union Cycliste Internationale).

There is a write-up on how the UCI denied approval of the RZR 46 leading to the creation of the RZR 46 Team.
