Für die einfach Begabten unter uns (frage für einen Freund):
Was bedeutet denn „no Record“ und Open-c
http://www.velo-retro.com/tline.htmlauf den record naben steht ab irgendwann record drauf, davor wie bei diesen hier nur campagnolo, also no record.
ebenso war das c von campagnolo auf dem hebel vom schnellspanner und auch auf den schalthebeln bis irgendwann offen, wie ein E ohne den mittleren strich.
wann was geändert wurde, müssen die echten experten erklären.
1958
The iconic Record 5-pin cotterless crankset is introduced; 151mm bolt circle, 44 tooth minimum chainring, pedal hole dust caps, relieved spider and raised pedal lip. The Gran Sport "con denti" (with teeth) track pedal is introduced; aluminum cage plates, 10mm length thread for steel cranks and rubber "O" ring. Also introduced are the Record one-piece alloy, small and large flange hubs (oval holes in flanges, oil hole clip and open "C" on quick release lever) and the seat post introduced in 1956 now has a narrow cradle version to work with the Brooks B17 "Mod. Campagnolo" narrow-railed saddle that has twice the range of fore and aft adjustability. A patent is granted on hollow chainring bolts with Allen key hole and crank bolt cover with Allen key hole.
1963
Introduced in October, the Record bottom bracket marked "CON SFERE DA 3/16" using 3/16" balls instead of typical 1/4" balls. The races are pressed onto the spindle rather than machined directly on the spindle itself. Neither the cups nor spindle are interchangeable with bottom bracket components designed for 1/4" balls. Made for one year. A new wider base clamp design for the cable guides and down tube shifters along with thicker down tube shift levers with open "C" changed to closed "C". The word "Record" is added to the hub barrels and open "C" on quick release lever changed to closed "C". Thicker heads on seat post adjusting bolts. Next generation Record headset with non-domed lock nut, plain keyed washer. The low-cost "CAMPAGNOLO" model derailleur, an economy version of the Gran Sport derailleur (cadmium plate body and black oxide finish on pulley cage with the word "CAMPAGNOLO" on body), and also the low-cost Sportman rear derailleur are introduced. Record front derailleur has slot added to cable stop.
