On a period-correct build, the down tube levers dictate the character of every shift. This Suntour SHIFTERS D4 pair belongs to the friction-shifting era, where the rider's hand sets the cage position and holds it there. The set is built from steel and aluminium, with a Japanese production origin, and the condition report notes no oxidation on the surfaces.
Friction shifting character for classic road frames
The D4 designation identifies a specific Suntour lever configuration, one that sits naturally on period steel road frames. Friction systems tolerate mixed-component drivetrains better than indexed alternatives, which makes a set like this practical for a restoration that combines parts from different years or groupsets. The levers give direct cable pull without the notch points of later indexed designs.
For restorers working through a complete drivetrain, the Suntour SHIFTERS LV1 variant offers a related but distinct lever profile. On French builds, the SIMPLEX Eroica shifters are another period path worth comparing.

FAQ
What country were these Suntour SHIFTERS D4 levers made in?
These levers were produced in Japan, as listed in the technical specifications.
Do these Suntour D4 shifters show any oxidation?
No. The condition report explicitly states that oxidation is absent, so no rust or corrosion is noted on this pair.
What material are these vintage Suntour shifters made from?
The pair is built from steel and aluminium, which is a common combination for friction levers of this period.
Are these indexed or friction shifters?
The Suntour SHIFTERS D4 belongs to the friction-shifting generation. The rider sets the cage position by hand, and the lever holds it in place.
