REAR DERAILLEUR:
Huret Success Titanium (modified) - titanium upper and lower brackets marked with "T" inside a circle - forged light aluminum alloy shift arm - pivoting cable barrel mount - adjustable stop plate and demountable lower pivot bracket to accommodate either a 24 or 28 tooth maximum freewheel cog - 12 to 24 or 13 to 28 tooth freewheel capacity (adjustable) / 36 to 53 tooth front chain wheel capacity - rear body plate date code marked "MADE IN FRANCE 4077" for the fortieth week of 1977 - custom "drilled" and radiused stamped aluminum alloy pulley cage plates (...similar to what would later appear on 1980 to 1984 Super Success models) - custom milled alloy pivot pins and cable clamp bolt - model 2460 : Bullseye pulley wheels - Clear anodized aluminum alloy (Silver) - ten tooth design - NMB 6260 sealed cartridge bearings - width adjustable spacers - custom drilled ... [A period correct component of my choosing, albeit now thoroughly customized, and one of the fastest shifting, lightest, and yet durable rear derailleurs available from this era weighing in at a scant 170 grams in stock trim and a paltry 109 grams in the modified and yet still robust form seen here. The advanced Huret Success Titanium rear derailleur was truly "cutting edge" when introduced for public sale in the latter half of 1975 (...its moniker begot of the fact that the Sonolor / Cycles Gitane team had ridden these specially modified Huret Challenger components "successfully" throughout the preceding 1974 season) and arguably represents the pinnacle in both design and performance as achieved by the Huret brothers prior to a majority interest of their company being purchased by the German conglomerate Fichtel & Sachs AG in 1980. The original rear derailleur mounted to a Graftek G-1 sold as a "complete" bike would have typically been the venerable Campagnolo Nuovo Record model 1020/A.]
