Short Name: | SunTour AccuShift | Year Introduced: | 1988 |
Speed Range: | 6sp - 8 sp | Indexed Component: | Shifter |
SunTour Accushift is different than the Shimano SIS system in that it has a built in over shift in the shifter which moves the chain 1mm beyond the centerline of the cog to complete the shift, and then moves the guide pulley back to center the chain after the shift is completed. SunTour's rear derailleur also has little to no play in the guide pulley which forces the chain to be positioned directly under each freewheel cog, but this makes for less tolerance for being out of adjustment. |
