Malliard did make some "Dural" cogged freewheels. A couple of them were sold at eBay rencetly at just above $100, which Ithink were cheaper than what most Italian equivalentsgo for these days). Aluminum freewheel bodies and cogs have definitely been a weenie world item as titanium bb spindles are (very cool but could e scary in use), but it could still be useful for a C&Ver that putting together that sub-17 pound wonder thatall of us can appreciate.
