Actually, they are listed as 345 in their catalog. They look like they have a shorter sidewall then usual as well, very similar to the Stan's rims. Listed ERD is a slight bit different though, so I doubt they are just restickered Stan's rims (Sun makes those rims, don't they?). BTW, I just noticed Hayes has purchased Sun.Patchito said:This is their new scandium reinforced rim. They're listed at 330 grams, which would put them below Stan's or Am Classic, but their actual weights vs. claimed usually run about 15-20 grams more on the WW website.
I'd seriously consider these as replacements for the Valiants I've been running for about three years on my racing hardtail, but I haven't heard much about 'em. Anyone tried them with Stan's too?
