I’ve run an old kona kilauea ss using a magic gear 34:17 for 15 years with out any issues. As long as the chain line is good you shouldn’t have any problems but it depends on the frame, I believe konas were designed with a magic gear in mind
It might be an urban myth (a really geeky cycling one) but I believe they designed the chainstay lengths on there early hard tails so people could run them singlespeed with a ratio of 34:17
