Just be aware we are talking two different wheels here; the Roin wheels are great quality although an aluminum alloy, whereas the Marvic are made to original spec and magnesium alloy. The Marvic will be lighter for the same wheel and they offer the 10's with short or long ribs per original design.
I believe it is the Roin aluminum alloy wheels that Mr Fiat carries;
$1,405 for a 10" or they also offer a 17" dia. in 11" and 9" widths to suit more modern rubber availability.
