Yes, in 1989 SunTour introduced combination brake levers & thumb shifters that were AccuShift 7 speed compatible. They were offered for both the XC9000 and XCD 6000 ATB groups. Their respective part numbers were CL-XC02-U7 and CL-XD02-U7. This was the only year that they were produced, as in 1990 they were dropped in favour of SunTour's new X-Press shifters with two push levers. Good luck with the search.
