1987

AccuShift index shifting introduced on 5 road and 4 mountain groups.  There were many problems with mis-matched parts not indexing properly.  Shimano more tightly controlled the allowable component spec and had a 3 year head start on Suntour.  Shifting options include Index Power Control with positions for regular spaced indexing, Ultra spaced indexing and friction Index Friction Control allows shifting in regular spaced indexing and friction Index Control is standard spaced indexing only Power Control uses the retro friction for better control and Friction Control is just regular friction shifting

1990

AccuShift Plus ramped cogs and Power Ring chain wheels improved shifting performance.  Suntour X-Press under bar, two lever shifters.  Multi Mount control systems allow the shifters to be mounted inboard or outboard of the brake lever.  Licensed the Beast front shifting system from Browning.  The chain was shifted by hinged gates instead of a front derailleur.   Delivery was 18 months late and very few bikes actually used the system.  Below are some pictures of the system installed on nickel plated Team Marin frame.  It is functional but seems to have a mind of its own some time.  Click on the pictures to enlarge.

This is the control box. The signal from the shifter moves the "railroad switch" to engage the tab that hinges the chain ring assembly.	Picture of the hinged chain ring section. You can see the switching tab right below the crank arm.	Pretty simple stuff. "H" for a higher gear and "L" for a lower gear.

Some interesting numbers comparing Suntour and Shimano from 1990.  16 manufacturers used Suntour parts on 322 models.

Interesting chart showing the change in percentage of Suntour by manufacturer.

Other miscellaneous 1990 facts:

Round chainrings 63% vs. Oval chainrings 37%

Oversized headsets

4 of 16 companies and 28 of 322 bike models

7 speed gearing:

1988: 11%, 1989: 44%, 1990: 75%

1995

For 1995, the XC Pro and XC Expert components are still listed as available.  The major push is the new XR (XR 50, XR 100, XR 150)series of components being promoted as "Plug and Play".  Plug and Play allows the Suntour components to be used with Shimano drivetrains.  Most of the components appear to be pretty basic and never found widespread usage.  SR Suntour forks are 9005, 8005 and 7005. Ergo Tec and Ergo Twist shifters are still offered. US sales office closes January 1,  1995.

1996

US office re-opens and concentrates on lower priced components.  I've not seen any catalog info for 1996 so I assume that there were no parts available.

1997

Pretty thin catalog for this year.  Suspension forks include the Sierra Magic 9007(with elastomer or MCU elastomers), 7007 and 8007.  Components are all Plug and Play compatible and include the Giga 450, Giga 350, XR250, XR150 and SX50.  Components are pretty much limited to derailleurs, cranks, shifters (twist or thumb), freewheels and cassettes.  Most parts look to be fairly inexpensive and I am not aware of any OE spec.  Mostly sold as inexpensive replacement parts.

1998-1999

1998 Suspension Forks:  Duo Track 6000/7007, Sierra Magic 7500/8300/8500V/9007M and MG-XC Magnesium

1998-1999 catalog: Whole slew of new forks even some triple clamp design.  New cranks (including the Superbe road crank).  The better mountain bike cranks feature a "slingshot" looking design.  Shifters, derailleurs and cassettes still available.
