Hello, I have a mismatched pair of bar end shifters that I took off of my old 3x8 Marin that had been converted to drop bars. They worked well there. I now have a new/used 3x9 bike that I'd like to convert to drop bars. I believe that they are just friction. I will attach pictures. One is Raleigh, and the other is Suntour. They each say the same company name on both sides of their lever. Will the right lever work on a 9 speed? Thank you!
