Starting with the Cyclone Mk II derailleurs in the early 1980s, SunTour began using a flat coil return spring in its upper-end rear derailleurs. This kind of spring gives a very fluid return movement. To the best of our knowledge, no other derailleur maker has used this kind of spring.
Here's a disassembled SunTour derailleur showing the flat coil return spring.

SunTour XC Pro MicroDrive rear derailleur. New, $200.00/each
Part# 75300
- SunTour part# RD-XP00-SSB
- SunTour's MicroDrive system used smaller diameter chainrings and rear cogs, by reducing the number of teeth in both. This increased frame clearance and reduced weight. SunTour said it made for faster, smoother shifts and eliminated chain jam.
- Accushift Pro compatible
- Sealed bearing pulleys
A very tidy, efficient little derailleur.

SunTour LePREEL Mid-cage rear derailleur. Used, $60.00/each
- Produced mid to late 1980s
- SunTour sold this friction rear derailleur under both the "LePREE" and "LePREEL" names depending on how the company felt the different names would do in different markets. This created no end of confusion among SunTour fans. To cut the Gordian Knot: They are the same derailleur, with or without the final "L".
Mid-cage offers a sharp shifting derailleur and a good gear range.

SunTour BL GT wide-range rear derailleur. Used
- Both of these derailleurs were completely taken apart and fresh grease installed in the springs and pulleys.
- The "BL" stands for "Blue Line", a series of derailleurs intended to fit above the Vx and below the Cyclone derailleurs.
- SunTour part# RD-3300
- The BL derailleurs were made starting in 1981 and through at least 1984.
- Weight: 220 grams
- Though named "Blue Line", most BL derailleurs were made with black trim.
SunTour BL GT wide-range rear derailleur #1. Used, $80.00
- We tapped a new stop in the cage. It won’t pull up as much chain slack as before, but we wanted to save a blue Blue Line.
- This BL derailleur does have blue trim.

SunTour Superbe Pro short cage friction rear derailleur, good for parts. Used, $25.00
- Here's a great derailleur for spare parts.
- Produced 1983 - 1986
- SunTour part #RD-5200
- Sealed bearing pulleys.
- Factory specs say max cog size is 26, but depending on dropout geometry and wheel placement, it can sometimes be made to throw a 28.
disraeligears.co.uk said this about the SunTour Superbe: "Many people regard the SunTour Superbe Pro (5200) as the finest friction derailleur of all time. It was light, strong, extremely effective and constructed to fantastic tolerances from the finest materials.
"No detail was overlooked, from the aluminium hanger bolt and pulley bolts to the sealed bearing pulley wheels to the stainless steel pivots with Allen heads that were removable so that the gear could be completely disassembled."
It's missing a pulley
And from the back it can be seen that there are broken and bent pieces.
SunTour V-GT rear derailleur. Used, $50.00
- SunTour part #4900
- SunTour made several versions of this derailleur. This might be version 2C or 2D.
- It was produced from 1971 until 1973.
Hard to believe this derailleur is 50 years old.

SunTour VX-GT rear derailleur. Used, $60.00/each
- The VX was introduced in either 1976 or 1977 and was produced into 1981.
- The VX is essentially a slimmed-down SunTour V. It has more aluminum and has a neater, cleaner design.
- Our VX rear derailleur has been overhauled and is ready for use.
This will shift almost anything.

SunTour Cyclone shortcage rear derailleur, 2nd-style. Used
- Produced about 1975
- Made for a maximum cog of 26 teeth, but with a rear derailleur hanger dropping 32mm or more, it can handle a 28.
- Weight: Only 179 grams
- This is the second version of the Cyclone.
- This derailleur is a masterpiece of component design. The Cyclone probably shifted better than any derailleur in the world in 1976. The cable routing through the parallelogram is clever and simple.
SunTour Cyclone shortcage rear derailleur, 2nd-style #1. Used, $60.00/each
A bit scratched, but works perfectly well.
This is about as good as a friction derailleur gets.

Here's a page from SunTour catalog #59 from 1981:
For fun, here's a 1982 ad for Cambio Rino components, famous for their controversial copy of the SunTour slant parallelogram rear derailleur.
About the product line, Velobase.com wrote: Private-labeled version of the Cambio Rino Criterium crankset, with 'Excel' logo in place of 'Rino' on the crankarm flutes. Excel was a US manufacturer of lower-end components based in Franklin Park, IL, supplying the original Schwinn Bicycle Co. of Chicago and Sears Roebuck & Co's line of Free Spirit bikes. When production of those mass-market bikes shifted to Asia in the early 1980s, Excel moved upmarket, contracting with Cambio Rino to produce Excel-branded versions of Cambio Rino derailleurs, cranksets and seatposts.
