Product Description:
This offering is for a new-old-stock (and still retail boxed) Suntour Sprint 9000 (6-speed index shifting) partial drivetrain set. With respect to the shifting capacities and other notable specifications, we have included the following...
Rear Derailleur:
Index shifting compatibility:
6/7 speed (with Suntour branded or compatible shifters and freewheel/cassette)
Friction shifting compatibility:
several options (most 5/6/7 speed freewheels/cassettes)
Front capacity:
double chainring w/12T (max) difference
Rear capacity:
index/friction...23T/26T
Total capacity:
26T (combined front chainring and rear sprocket difference...also known as chain wrap)
Weight:
212 grams (per our digital postal scale)
Other notes:
The pulley cage length is the technical specification having the most direct impact on rear derailleur capacity limits. This particular model has a relatively short cage length...measuring 48 mm from the center of the jockey/guide (top) pulley to the center of the tension (bottom) pulley. The cage length is slightly shorter than Shimano's designated "short cage" length of 50 mm, so this Suntour rear derailleur should compare (in terms of capacity limits) to similar Shimano branded models with the short pulley cage. The primary benefit to a shorter pulley cage is less weight (although, in all honesty we are only talking about grams here, so probably not a noticeable savings for most of us). The downside, as most already know, to a shorter pulley cage is lower capacity limits, which limits these derailleurs to double crankset road bikes with a relatively narrow gear range on the freewheel/cassette.
Having said the above, Suntour specified different capacity limits for this rear derailleur when in friction mode vs. indexing mode. Our experience, however, has been that friction mode capacity limits are attainable in indexing mode when care is taken to practice good shifting habbits. In other words, avoid poor chainline gear combinations that place unnecessary stress on the drivetrain.
Shifters:
Index shifting compatibility:
6/7-speed (with Suntour branded or compatible freewheel/cassette)
Friction shifting compatibility:
Several options (most 5/6/7 speed freewheels/cassettes)
Mounting bracket/spacers:
Braze-on model w/curved spacers
Weight:
109 grams (including mounting hardware and cables/housing...just as pictured)
Other notes:
The left-side shifter is designed for friction-mode only (although it does incorporate Suntour's ratcheting design, so the shifter makes a series of small "clicks" as the lever is pulled through the gears), so it should be compatible with most double/triple cranksets. The right-side shifter has three adjustments/settings that allow for 6 or 7 speed index shifting or friction-based shifting (although, the right-side shifter does not incorporate the same ratcheting design when switched over to friction mode).
Other drivetrain accessories include a set of shifter cables and two pieces of cable housing. The longer of the two pieces is typically used around the rear chainstay to protect the cable in this area as it loops around and enters the rear derailleur. The shorter of the two pieces is often used when there is a cable stop on the down tube and the seat tube that helps with the transition of the left-side cable from the left shifter to the front derailleur (and this assumes this shifter cable is routed above the bottom bracket shell).
Freewheel:
Model:
Winner Pro 6-Speed (WP-6000)
Cluster:
13-14-16-18-20-23
Threading Specifications:
British/English, so it's 1.370" x 24 tpi (threads per inch)
Index Shifting Compatibility:
6-speed (with Suntour indexing capable 6-speed shifters and rear derailleur)
Friction Shifting Compatibility:
Yes (many compatibility options)
Weight:
398 grams (per our digital postal scale)
Other notes:
As most folks already know, the Winner Pro model freewheel is Suntour's top-end.
This is a rare and very good quality partial drivetrain set from the late 80's (and among the first to incorporate Suntour's index shifting (Accushift) technology). We should also note our Suntour catalogs make a clear distinction between their sport/recreation components and their competition-level components. To this end, the Suntour Sprint components are always included among the latter...and near top-end...with only Suntour's Superbe Pro groupset above it. We are not saying the Sprint components are the equivalent of Superbe Pro, but they are in the discussion as Suntour competition-level components designed for the additional stresses brought about by competitive cycling.
As for condition, our limited stocks are retail boxed and show fairly well...with only minor shopwear noted. Probably the most visible of the shopwear (light scratches and scuffs) tends to show up on the shifters. We sell these shifters individually as well, and the polished silver finish must really be susceptible to scratching (as most of these shifter sets will have cosmetic scratches on the lever bodies...even though they have been packed/preserved fairly well over the years).  We should also mention the finish on the rear derailleur is a combination polished silver and blue/gray enamel (painted)...and generally shows well. The Winner Pro freewheel is finished in Suntour's traditional silver color for these top-end units.

Note to international customers regarding shipping...
We apologize to those that feel some of our international shipping charges are too high. We only charge actual shipping rates, but once an order exceeds a certain amount, we hesitate to use the least expensive US Postal Services First Class International service. We feel this way, because this service is not trackable or insurable...so more risk of loss. We prefer the US Postal Services Priority Mail International service for more expensive orders, because this service is trackable at USPS.com and insurable...so less risk of loss. Unfortunately, this service is more expensive, especially for smaller/lighter packages, relative to the First Class International service. We are sorry about these higher shipping costs, but hopefully our notes help to explain why this is the case.
Note to international customers regarding customs...
We also apologize to those that feel their country import taxes, duties and brokerage fees are excessive. As a small US business, we are required by customs' laws to declare each order as a retail sale. Additionally, the declared order value must be equal to total store purchases and/or winning auction bids (less any shipping costs, as these are not considered in the declared value). As a result, each customer will be responsible for paying his/her own country taxes, duties and brokerage fees, which will be collected upon delivery. Again, we apologize for these additional costs, but we cannot afford the penalties and fines that come with breaking customs' laws...so we have to strictly abide by them.
