New-Old-Stock Suntour GPX Front Derailleur...Clamp-On (28.6 mm)
Thank you for your interest in this item and please visit our store for other offerings. We have very reasonable shipping terms and combine orders to save money (for customers) on shipping costs. We also maintain customer friendly return/refund/exchange policies.

Product Description:

This offering is for a new-old-stock (NOS) Suntour GPX front derailleur from the very early 90's. Some of it's more prominent design features include...

  • Compatibility: marketed as road bike model during the 6/7-speed freewheel/cassette era (although see notes that follow for other drivetrain possibilities)

  • Capacity: double chainring with 16T (max) difference (shop catalog specs)

  • Mounting bracket: clamp-on (28.6 mm) 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: 98 grams (per our digital postal scale)

We sell a number of Shimano front derailleurs and this Suntour model holds it's own when compared to many of them (probably falling somewhere in the Shimano 105 to 600/Ultegra quality range...our best guess). The finish most closely resembles the vintage Shimano 600/Ultegra front derailleur from around the same era, as the hardened steel chain guide/cage is nicely chromed while the aluminum alloy body is lightly polished around the clamp area and painted with a dark gray enamel elsewhere. The resulting contrast in colors makes for a nice finishing touch on a very good quality front derailleur.

We should also mention that all of our Suntour catalogs make a clear distinction between their competition-level components and other (lower-level) offerings, and without exception, the Suntour GPX groupset is always included in the competition-level category...and in the same company as Suntour's Superbe Pro and Sprint groupsets. We are not saying the GPX components are the equivalent of Superbe Pro, because they are not...but they are in the discussion as a competition-level groupset designed for the additional stresses brought about by competitive cycling.

In terms of their condition, these are all very nice cosmetic conditions.

General note regarding narrower/wider front derailleur cages (chain guides) and chains...
We do not see many good quality clamp-on front derailleurs with these slightly wider cages, which are typically more effective at shifting the wider chains desired on some vintage road bikes. Narrow chains may also be used with these vintage setups, but because they are typically more expensive and usually not as durable (because they are made with thinner/lighter component pieces)...they are probably not the best alternative for a vintage road bike. Wider chains are usually a better option, because they are made with thicker/heavier component pieces that will generally hold up better over a longer period (so more miles between replacements). The problem is that most of today's front derailleurs are built with cages to accomodate extremely narrow chains (for 9 and 10-speed shifting), which means they might not work as well on a vintage road bike when a wider chain is preferred (for the reasons noted above). In many cases, it's still possible to get the newer front derailleurs to function...but with a narrower cage and a wider chain, it would appear the limit screw adjustments have to be near perfect to eliminate chain rub (so little margin for error here...and hence the reason the slightly wider cage on these older front derailleurs is a nice feature).

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 more risk of loss. We prefer the US Postal Services Priority Mail International service for more expensive orders, because this service is trackable at and 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' we have to strictly abide by them.
