Is it possible to convert the suntour down tube shifters (2 chainring in
the front and 8 at the back) to bar-end shifters? If so, any
recommendation?

Thanks, Tony

Go to the rivendell website. They have this bar end adapters. You attach your
shifters to the adapters and you plug them in the end of the bars. They work
great. Here is the link:
