Campy shift lever question.
I asked the following questions in the "Mechanics" section and only got "the threads are probably the same" which didn't help much. Does anyone here know?
Is there a difference between the Campagnolo friction adjustment wing nuts between a frame mounted and a bracket mounted downtube shift lever? It would appear I need a wing nut instead of a wing stud for my bracket mount - am I correct? The bike is a 1975 Holdsworth. Thanks.

Part 604/1, called the "Friction adjusting wing nut" in the catalog is interchangeable between the braze-on and clamp-on downtube shifters. If that is what you are referring to, if not, pictures could help.

they are the same... they are both 'studs' or bolts or screws or whateva
if you are going from band-on to braze-on, you might need the washers and stops, however
(by the way, I'm looking for a washer or two, since it seems you are going in the other direction...)
edit/pic for an idea:

Yes, Campag. downtube levers take "wingbolts," which are commonly mislabeled "wingnuts." It's sort of like owning a late model VW/Audi, which uses lugbolts, which lots of folks erroneously call "lugnuts."

well.. i was looking for some steel washers as used on the slightly earlier shift levers to match the one i already have..
but the plastic washers are the same size and also interchangeable with lots of other shifters like suntour, etc...

I found a set of cheap, NOS Victory or Triomphe downtube shifters off Ebay to get the washers, as far as I can tell they're not sold at Loose Screws or anything. Fortunately, they were compatible with my nuovo record shifters and I haven't looked back since.

I still, for the life of me, can't figure out how to tell the difference between Campag shift levers. Actually, that's the case for me with most of their parts, but the levers in particular.

Here is a correspondance I received:
"The originalCampy shift levers(startingabout 1955), whether brazed to the frame or clamped-on,usedathreaded male screw(wing nut, D-ring screw, etc).* Beginning in the 1960sCampy introducedthe lower-priced Sport and Gran Sportshifters, which had the male threaded stud mounted, and used a large diameter round internally threaded wheel (or nut)."
There is a difference between nuts and bolts (studs). A nut has internal threads and a bolt (stud) has external threads. I'm looking for Campy nuts. Thanks for the responses. Skip

yes the nuovo gran sport had the knurled type adjusters..
but i didn't think they made any braze-on type shifters of this sort
i'm not sure i understand what your question is...

Hi Coelcanth,
I think my question was "Did the Campy downtube shifters have two types of friction adjustment knobs?" And I think the answer is yes and I think the braze-on type shifters had a nut brazed onto the frame so the adjustment "nut" was actually a stud with a cap and the clamp-on shifter came in two flavors: a nut and a stud on the clamp-on part - the nut required the stud (with cap) and the stud required a knurled type tension adjuster.
