Having copied the 1971 Shimano Crane with their first New Success model, Sachs-Huret turned to the 1985 Shimano Dura-Ace 7400 as the basis of their second try - the 1987 Sachs-Huret New Success ARIS.

This is a classy piece of work. It’s a proper slant parallelogram design with two sprung pivots. The angular styling and the placing of the adjustment screws make for an individual look, and it has a spring loaded ‘cable saver’ built into the adjustable cable outer stop. It is more Shimano 600 quality than Dura-Ace, but it is a competent, composed design nonetheless.

ARIS stands for Advanced Rider Index System, Sachs-Huret’s answer to Shimano’s SIS. ARIS worked reasonably well, but lacked the degree of attention to chains and freewheel cogs that set Shimano’s system apart.

Note that,on the logo on the rear of this derailleur, ‘Sachs’ is writ large and ‘Huret’ has become vanishingly small.

This is a pleasantly tidy example of a later version of the short cage New Success ARIS (47.2D). Some of its distinguishing features include:

• It is anodised grey.
• The main b-pivot bolt takes a 5mm Allen key.
• The pulleys and the small plastic piece at the cable adjuster are dark grey.
