SunTour Sprint 9000 rear derailleur. used $100.00

Part# RD-83

SunTour part#: RD-SP10-SSB

In 1987 SunTour redesigned the Sprint components. The rear derailleur got a new cage, parallelogram and name. It became the Sprint 9000. This new derailleur was produced from 1987 until 1990.

It will index 6 & 7 speed Accushift Winner Pro freewheels with the correct Sun Tour indexing levers.

SunTour meant for the Sprint components compete against Shimano 600 and to fit between Sun Tour Superbe Pro and Cyclone lines.

Weight: 200 grams.

SunTour AG Tech RD-5000 super wide-range rear derailleur. Used, $50.00

Part# RD-84

In the early 1980s SunTour began producing extraordinarily wide-range freewheels, topping out at a 14-38 five-speed monster. That 38-toothed cog probably remains the largest rear cog to have been commercially available.

But how do you move the chain around such a stump-pulling gearset? The answer was the SunTour AG (for "Alpine Gear") rear derailleur. We believe this derailleur was produced from the late 1970s into the early 1980s.

Our AG Tech is the summit of Sun Tour's wide-range derailleur production. We admit it's not pretty. But it is supremely effective. Though designed for 5-speed rear cogsets, on some bikes it is said to be capable of managing 8 or 9-speed cassettes.

It is almost entirely steel, except for the rear parallelogram body.

Ours includes a SunTour hanger-clamp for a bike without a rear dropout/hanger.

Before posting it for sale we overhauled this derailleur.
