Suntour Accushift derailleur - reviews?
the bike I'm currently looking to purchase has had the original Sachs Huret Rival derailleur replaced with a Suntour Accushift (model unknown), I know Suntour is Japanese and have read the Accushift was an attempt to counter Shimano's new models but in general the reviews and comments I have read are all unfavorable. Do any members have personal experience with these and if so what are your opinions?

It works and it is well made. It does not index as nicely as Shimano. I currently have two accushift bikes and run them both in friction.

The OP doesn't say anything about the shift levers and whether they are only friction or are indexed. The Sachs indexing specs are a match to Shimano, the Sun Tour isn't. If one tries to mix and match with indexing shift levers the Sun Tour rear der will kind of but never really index across the entire range. Maybe a couple or three shifts will sort of be Ok at best. With friction all will be good.
Also not mentioned is which grade of Sun Tour der is at play. Like other brands Sun Tour used a series name (Accushift) on a number of ders. From inexpensive stamped steel units to finely made forged and machined Alu ones. The low cost ones were, well, cheap and have less precision in their function. The nicer ones were nicer. But as an indexed system all were a step behind the Shimano counterpart. Andy.

The photo shows a der with some stamped steel and some machined Alu. It looks to be a mid grade der. Maybe an Alpha 3000, or it's variant.
Still out there is the shift lever issue. Andy.

they wanted into the index shifting game & OEM Build spec list too ..
Sun tour had the Patent on the slant pantograph , to them selves for many years .
when it expired everyone else adopted it ..
Parallelogram pivot pins on shimano's were vertical as was My old Rally Campag..
sun tours design let the pulley assembly move at an angle closer to the shape of the freewheel/cassette cluster.

I have a bike which has SunTour XC Sport 7000 rear derailleur, Suntour XC 6-speed freewheel, and SunTour 6-speed index/friction thumb shifters, and it all works well.
In order for Accushift to work well, you'll need shifters, derailleur and freewheel designed for Accushift. I do understand that many have gotten various combinations of different brands of shifters/derailleurs/freewheels to play nicely with each other, but I have no experience with that.

The levers look to be friction so I suspect the shifting with the ST der will be fine. Andy.

My C'dale has an Accushift drivetrain and it works great. Has a very loud, crisp click to the shifters (Ole shifters, to be exact), though the shift action at the freewheel/RD isn't the most refined thing in the world compared to Shimano indexed downtube shifter drivetrains I've heard. However, it works every time, clunk and all.
