Yes, but where do my "D" holes fit into all this. I was told that they were factory original to the GTA......but who knows? What do you think?

All my 6" Campys have the D-shape. I think that the ones without may be an early casting before they figured out that this may be a weak spot.

That's a good thought.

Well, there have been a lot of replies to this thread. I saw some pictures of GTA wheels and I thought I'd add some more.

The first 3 pictures are 6x 14" Tecnomagnesio's, the second 3 are 7x14" Campagnolo and the last 3 are 7x15" Alfaholics replica's.

And the other 4 pictures.

my Technomagnesios have the lettering inside the rim...


We're missing a pic of the HB GTA wheels here, the 6.5x14s

hello all

im trying to gauge if there is any interest here to purchase new 14x7 techomagesio wheels on the bb. today i paid a visit to the old north american technomagesio distributor to see if he can get more of the 14x7. he said they are unavailable for some time and but he knew were the molds were in italy and it may be possible get a batch re-casted. he mention it would be fairly high cost due to the poor exchange rates and high shipping cost compared to past. he guestemated it would 550-700usd per wheel. most likely we would have to order a minimum of 10 sets to make it worth while for the guys in italy. they will be like the orginal tecnho's (cant remember the ET off hand) only without the techno licensed trademark. if there is interest i'll start a new group buy thread.

heres a little campy/techno history ive posted from another thread. http://www.alfabb.com/bb/forums/alfetta-gtv6-1975-1986/150182-looking-hens-teeth-campagnolo-wheels.html
please keep in mind this what i vaguely recalled back in the early 90's please free to correct or contribute any further information that pertains the techo/campy saga.

happy new years

In 1993 I bought 5 Tecno's from Alfa Ricambi since I worked for a alfa shop and bought 5 I paid $440.00 a piece for them regular price was about $550.00 to $575.00 each. There still in the box that alfa ricambi sent them in. Still haven't finished the restoration yet. There size 14x6.

Sorry this is a bit late, but catching up on AlfaBB...

Original Campagnolos:
There were, I think, two different nave patterns, one with D holes, one with all round holes. I THINK the ones with D holes were used for certain rim sizes, presumably where the section between the rim and the nave, into which the valve hole is machined, was at a shallower angle, to give a little more clearance around the valve. I am assuming here that the casting is made with the rim very roughly formed, and it is then machined down accurately to the correct size. Campagnolo made 6", 7" and 8" versions, and I suspect that the D holes were used for the 7" and 8", and the round holes for 7" and 6". That would be why the 7" versions come in both formats. Campagolos are for decorative purposes only these days, in my opinion. I've seen plenty of cracked ones, and they're all going to be too old for use these days. Sure, buy them for the sake of completeness, but don't use them

Technomagnesio:
I bought my Technos in 1986, and they were exactly the same as those in the pictures on Zowie's posting above - 'Technomagnesio' machined into the nave between the bolts, and a smooth interior - no ribs. They're great copies, but heavy. In fact, I think they're aluminium, not magnesium, because they don't suffer pitting like magnesium wheels do when they get scratched and wet. (Water pits magnesium FAST). They're great wheels though, and mine are in excellent condition despite 20-odd years of use

Others:
As I say, original GTA Campagnolos are extremely dodgy for use - I would never fit them to my beloved little GTA. Were I buying today I'd go shopping at Alfaholics or Classicalfa websites: There have been some real advances in technology, and the wheels currently on offer from both these sources are strong, safe and look superb, as well as being light. There may be other sources: the two I mention are both organisations I use and trust completely. Use their websites - they're a mine of useful, expert information

In that case, there must have been more than one version of the Tecnos. Mine were anything but heavy at between 11 and 12 pounds for a 14x7.

Will,
As a matter of interest my 6" Campagnolos have "D" shaped holes either side of the valve. I was told that this was done to balance the weight of the wheel after the metal removal for the valve stem....!!!!

Hi Stuart,
I could well have got it the wrong way round - I am just thinking out loud, and offer my thoughts for the sake of discussion rather than fact.
Cheers, Will

My 6x14 Tecnomagnesio GTA wheels weigh 4.45KG, so definitely magnesium
