Bertin bikes continued to expand their distribution during this period of the Bike Boom. Framesets were built with Vitus supplied Durifort/888 tubes and, later in the decade’ with Vitus 172 as was the case for the C 37 bis. Some higher end bicycles and framesets like the C 35 were built with a Reynolds main triangle and Vitus for the rest. Specific models like the C 37 and C 38 remained all Reynolds. Framesets were built using forged ends and braze-ons gradually reappeared on the higher end racing frames.
French equipment was the basic specification on frames, but in the mid-70s, Bertin became the French Shimano distributor and its gruppos proliferated through the lineup during this decade as an upgrade before the fullout Campagnolo option. The house brand Milermo equipment was speced extensively on everything from dropouts to saddles, to stems, tape and almost any other accessory required to complete a bike.
Bertin dabbled as well with non-traditional materials such as welded aluminum in the C 80 and welded titanium in the C 75T although these never became a major part of the Bertin lineup.

This French equiped early 70s Bertin C 117 was located in the archive section of Bike Forums from 2006. Bertins of this size were built from heavier gauge tubing to compensate for greater stresses and higher rider weight – not a universal practice for many other manufacturers.
The details above show the OEM stainless fenders and chromed rack of the C 117 from the photo above. The original front rack has been removed and replaced with a suspended bag rack like Velo Orange’s. On the lower photo note the generator mounting tab on the left seat stay. The wiring and generator appear to have been removed.
Bertin supplied the C 34 with tubulars as standard equipment in the 70s. This particular C 34 is fully French equipped even to a Bertin logoed water bottle.
A Japanese website in 2009 supplied this image of a small C 34 with Weinmann 500 sidepull brakes.
Bertin also built its C 34 model with clincher tires. That variety was designated C 34 bis. On this bicycle, there are Simplex derailleurs and a Stronglight 49 crankset. Note the red accented Milremo stem.
The generator/light combination on the rear stay identifies this bike as a Bertin C 132.These could be supplied with either dropped bars or the touring style bars as shown. The saddle is a quilted, padded, plastic based Milremo.
Another C 34 found on leboncoin from France.
The Bertin C 132 above retains its cellulloid fenders but is missing the original generator and taillight usually found on the non-drive seatstay.
Except for tires, original equipment chacterizes this Bertin C 117 mixte. Note the Mafac white plastic brake levers and the alloy wing nuts for wheel retention.
