[MENTION=333224]juvela[/MENTION] I've never seen a Bertin with Huret dropouts. Maybe in the 1950's and very early 60's but they were very different dropouts than the designs from the mid 60's on.

Also, I don't recall seeing Simplex dropouts used on Bertins???

Bertin used Campagnolo dropouts on their top models from the early 1960's up through the 1980's.

Early 60's Campy dropout on a Bertin C-37 frame. Notice the inserts in the tube ends.



Late 60's C-37 with later style Campy 1010 dropouts and the tube inserts too.



1985 Bertin C-37 with Campagnolo 1010B short dropouts.




For a while Bertin used Campy stamped steel 1010-1 dropout on some of their mid-range models like the C-34. The bike pictured has a Huret Alvit rear derailleur mounted on a Campy 1010-1 dropout. Alvit derailleurs were very popular with the French - over 5 million of them were sold between 1958 and 1965! They were the French "answer" to the all metal Campy derailleurs (as opposed to the Delrin Simplex derailleurs).




By 1976 many mid range bikes especially the Japanese makes were coming with rear dropouts with integral derailleur hangers.

The mid-range Bertin models that we imported had stamped steel dropouts. We approached Bertin to have them start using Campy rear dropouts on those bikes.

Bertin came back to us and said that Campy dropouts would cost us an additional $15.00 USD per bike... But, they could use Milremo dropouts instead. They were made by the same company (Technociclo) that made Campy's dropouts for only $6.00 USD additional! No brainer!

There were several versions of Milremo dropouts that Bertin used. the first picture show the dropouts that are identical to Campy 1010 style. Notice the "hump" on the last picture.




Bertin was the importer/distributor for Shimano in France from the mid 70's until Shimano bought them out in 1990. They started using Shimano Shimano vertical dropouts on their top of the line "pro" models like the C79-SSC and C80-SSC.
