Simplex Retro friction Shifters Part 2

According to velobase the next available version of retro friction shifters were produced by Simplex for Gipiemme in 1982.  These shifters are the ultimate version of retro friction shifters.  Not only were they the lightest version (70 grams) of retro friction shifters, but also easily the most attractive.  Looks and weight aside, these shifters are almost totally sealed.  The entire spring mechanism is held within the shifter body, therefore making  the shifting mechanism almost impossible for dirt and grime to infiltrate.

Often referred to as "coke spoon" shifters, given their elegant, spoon like shape, these shifters were likely able to shave extra weight by incorporating shaved down contours and less bulky shifter stops than on the "tear drop" style, which can be seen in the photo below.  The production of these shifters appears to have been quite limited as they were only available for a very short period of time.  Likely the cost associated with the extra nice polishing and more intricate shape made these shifters too expensive to continue producing.

Also around this time, Simplex began producing a newly styled version of their shifter lever.  Simplex removed the original "S" encircled with a star and replaced it with a "tear drop" shaped handle embossed with the company name.  The reason for this change was more than likely to reduce the weight of the shifters.

The earliest example of these levers I could find was in a french Peugeot catalogue from 1983.  These new style shifters appear on what I believe was Peugeot's introduction of the carbon fiber frame (PY 10 FC), which would give further credence to the idea that the design change was a weight saving measure.

Aside from the change in looks, the shifter was still identical internally to the second generation shifters.  The weight was reduced by 20 grams, from 95 to 75 grams.  These shifter were still available in clamp-on and braze-on models.  During this time Simplex also produced these shifters for Spidel, Mavic and Gipiemme.  Spidel shifters had their name embosed on their shifters.  Mavic and Gipiemme shifters were identical, varying from the Simplex shifters by the fact that they were unbranded.  The unbranded shifters were available in both silver and a black anodized version and were included in various Mavic and Gipiemme groupsets starting around 1984.

The "tear drop" version of retro friction shifter were likely produced until the late 80s when Simplex began their demise by bankrupting for the first time around 1985.  There was one more version of the retro friction to come, which was produced by Mavic and included in their ZAP groupset.  The Zap groupset was first introduced at the 1992 Tour de France and later publicly available in 1994.  Only the left shifter was retro friction.

This concludes the history I was able to dig up on the retro friction shifter.  If I come across any more info I'll make an updated post with corrections and/or new info.  Next post will likely be on my selection of brakeset.
