Well Said There Hugh ! Let me add some additional points about Campagnolo cast wheels for automobiles and motorbikes :
As always , when discussing Campagnolo , or when having any questions about Campagnolo , SEE THE CAMPAGNOLO TIMELINE :
http://www.velo-retro.com/
In particular , see the listings for the years , 1960 , 1961 , 1975 , among others .
Also , if you have any access to old Road & Track magazines , see the advertisements for Alfred S. Cosentino's business , FAZA USA . The ads were in that magazine every month , at least during the early to middle 1970's . The ads quite often mentioned ( with photos ! ) the satellite chassis which was custom cast by Campagnolo , from "Elektron" ( magnesium - aluminum alloy ) , and sent into space by NASA !! Mr. Cosentino's company was a major source for Campagnolo wheels for sports cars .
Another big name in sports car parts was Bayless . Seeing all of the references to Bayless Engineering , and Bayless Inc. , when I was younger , is the reason that I now have such a hard time spelling the name , Brian Baylis ( sorry about past mistakes there Brian ) !!
If you're curious , and you download the Bayless catalog , page 8 has photos of Campagnolo wheels . The ones I know are Campagnolo wheels are numbers , 10 , 12 , 14 , 15 , and 16 .
And during the late 1960's and early 1970's , Campagnolo experimented with some very odd designs for unsuccessful brakes , for small road racing motorbikes of approximately 125cc .
But basically , Campagnolo cast a quite a few wheels for Ducati . And yes , there were sometimes problems with those wheels . When Cook Neilson ( yes he spelled it Neilson ) was racing his "California Hot Rod" Ducati Super Sport ( twin cylinder , bevel drive heads ) , he had his Campagnolo wheels tested for flaws ( x-ray ? zyglo ? ) . They did not pass the test . He wrote in Cycle Magazine that he hated to not use them . But , with a top speed of approximately 150 MPH . . . I hated reading that any Campagnolo part had failed any test . I wanted to read that Campagnolo wheels had won the Daytona 200 mile race !
BUT ! But most of all , we are supposed to be knowledgeable folks here . PLEASE do NOT call a one-piece , cast-alloy wheel , a "rim" . It is a wheel . It HAS a rim . But the rim is cast as part of the wheel . It has a rim . It is a wheel .
A rim is a separate part of a wheel .
Anyone who has worked behind the counter at a bicycle shop has the FRUSTRATING experience of dealing with the customer who does not understand the simple differences , between the simple terms ; Rim , Hub , Wheel , and Tire .
When a customer asks for any one of those four items , he or she may very easily be really looking for any of the other three items !!! Then , we play 20-Questions trying to figure out what they REALLY need !!!!
Sorry for shouting so much . I get frustrated when people confuse the terms rim and wheel .
I always wanted to make a large display board , with well lettered flash-cards on it : "this is a hub" , "these are spokes" , "this is a rim" , "together they make a wheel" , "this is a tube" , "this is a tire" , "they go on the wheel" ,
"if you have a flat tire , you do NOT need to ask for a new wheel !" "if you buy a new rim , you will need to lace it up into a wheel !" . . .
