Hi all, my new wheelset is completed! I got Spada Oxygeno 18+24 spokes, plus today arrived IRC Formula Pro light Tubeless tires, 240 g each.
The setup was very easy, nothing to compare to my previous DA 7850 SL and Hutch Atom, which were really a p.i.t.a. to get on.
I used only some soapy water and the tire went straight on, almost by hand.
I rode them for a 30 km spin, and everythings ok, the wheelset is very light: 1150 wheels + 480 tires + 20 rim tape + 14 valves

Uphill is wonderful, very very responsive yet confortable, I run it at 6.5 f, 7.0 r., my weight is 63kg

Very nice!. That's incredibly light for clinchers. Do you have a source or link for the wheels?

Yes, http://www.spadabike.com/prodotti_ruote.html" onclick="window.open(this.href);return false;

Spada is a small shop in Tirano, near Passo Mortirolo, he himself produces hubs, while rims are Stan's and spokes a mix of Pillar and Sapim.

Sorry it's only in Italian, if you need I might translate. I spoke to him by phone,he's very kind and skilled, and his hubs are really interesting: no tools needed to open them.

You can save more weight by getting rid of them. :smartass:

Valve caps - OK, but you need the nuts on tubeless.

I had also on DA wheels, Shimano originals. Without nut, the valve looses air!

Does anybody know a supplier who can import these to the US or know somebody in Japan who can buy in bulk and ship them here? I feel like there's decent demand for these tires, but the only online importer is gouging the prices at like $150/tire.

Why don't you give it a shot? IRC might let you order, but chances are the minimum will be a few thousand $$s worth. See if you can organize a bulk by through WWs to help cover the cost.

Honestly, I don't even know where to start. There is 0 contact information on their English website. There are basically 0 US distributors for IRC bike tires, and the bike tire division of the company seems to be the tiniest of tiniest subsidiaries of the gigantic Inoac industrial company: http://www.microsofttranslator.com/bv.a ... 7%E3%83%B3

I talked to irc at interbike. They will be distributing their tires, including the formula pro light tubeless tires, in the US. I'll try to get timing information.

I assume they are the original (lighter) Stan's 340 rims. I didn't know you could still get those.
