Product Description:
This offering is for a new-old-stock (and still retail packaged) Suntour 4050 shifter/derailleur 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/14T (max) difference
Rear capacity:
index/friction...24T/28T
Total capacity:
28T (combined front chainring and rear sprocket difference...also known as chain wrap)
Weight:
257 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 56 mm from the center of the jockey/guide (top) pulley to the center of the tension (bottom) pulley. The cage length is slightly longer than Shimano's designated "short cage" length of 50 mm, so this Suntour rear derailleur should compare favorably (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 habits. In other words, avoid poor chainline gear combinations that place unnecessary stress on the drivetrain (and please see the more detailed note that follows regarding Suntour drivetrain capacity limits).
Front Derailleur:
Compatibility:
marketed as road bike model during the 6/7-speed cassette/freewheel era
Capacity:
double chainring with 18T (max) difference
Mounting bracket:
clamp-on (28.6 mm)...so should be compatible with many vintage steel tubed road bikes that require a clamp-on unit
Cable pull:
bottom (so cable routing must enter from below the unit)
Design:
conventional/bottom swing
Weight:
102 grams (per our digital postal scale)
Other notes:
The derailleur cage (or chain guide) should be wide enough to accommodate most wider chains found on vintage road bikes having standard spaced 6-speed drivetrains (126 mm rear spacing) or even standard spaced 5-speed drivetrains (120 mm rear spacing). This is critical when considering most newer front derailleurs are designed with narrower cages to accommodate narrower chains.
Shifters:
Index shifting compatibility:
6-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/built-in 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 does not incorporate this same ratcheting design when switched over to friction mode.
The Suntour 4050 product line is good quality in a sport/recreation offering. It was not intended for competitive cycling, but it borrowed from Suntour's competitive cycling technologies to provide a good quality offering and respectable performance for a reasonable price. We have better quality drivetrain components available, but for most non-competitive applications, these components are probably a good fit...and especially for those that are trying to resurrect an old stock index shifting Suntour drivetrain (as Suntour ceased production of such components in the early 90's).
As for condition, our limited stocks are retail packaged (in sealed/heavy Suntour branded plastic bags) and show fairly well...with only minor shopwear noted.

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.
