The Suntour EDGE product line is good quality in a sport/recreation offering (and succeeded the 4050 groupset from the late 80's). This model rear derailleur was not intended for competitive cycling, but it borrowed from Suntour's competitive cycling technologies to provide a good quality component and respectable performance for a reasonable price. We have better quality rear derailleurs available, but for most non-competitive applications, this is 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). Listing Update...We've had some customers ask us about the black material that makes up the backside of the pulley cage.  To this inquiry, I can confirm this material is a hard (and fairly thick) resin/plastic.  I guess I'd prefer the entire pulley cage to be made out of a metal, but maybe Suntour's thinking was to save a bit on weight and that this material would adequately handle the stresses of non-competitive cycling.  For what it is worth, we've been selling these derailleurs for a number of years and feedback from customers has been good (with no complaints or returns of one of these units due to premature failure of the pulley cage).

As for condition, these units were bulk packed in plastic bags. As a result, the two-tone gray enamel finish generally shows some shopwear (scuffs/scratches), but they still show fairly well overall.  Please also note because we are nearing the end of our stocks in these rear derailleurs, I have begun updating the pictures to reflect the next unit that will ship.  I've also attempted to take some close-up pictures to show some of the scuffs/scratches, but such blemishes do not always show-up as well in the pictures relative to what we see in person (and just want to be honest here). Please also note that while we may have multiple quantities listed for sale, we will repeatedly update the pictures to reflect the next offering that will sell/ship.

Note regarding Suntour specifications (drivetrain capacity limits)...
We realize catalog specifications concerning drivetrain capacities tend to be conservative. As a result, they may generally be exceeded with slightly taller rear sprockets and total gear differences that exceed recommended limits...as long as proper shifting techniques are practiced to achieve preferred gear combinations. Manufacturer specifications generally consider worst case gear combinations when listing maximum drivetrain capacities, so as long as these combinations are avoided, riders are generally able to exceed catalog specified capacity limits. We realize most individuals scanning this listing are already well aware of proper shifting techniques that achieve preferred gear combinations, so we'll limit the discussion to the most basic of premises...and that is to maintain a chainline that is as straight as possible when making gear selections. For example, there should never be a need for a gear combination that includes the smallest chainring in the front and the smallest sprocket in the rear...or alternatively...the largest chainring on the front and the largest sprocket in the rear. These are the most extreme gear combinations that put undue stress on a drivetrain. As a result, avoiding these extreme gear combinations (as well as other gear combinations that approach these extreme examples), should allow each rider to squeeze a little more capacity out of a drivetrain.
