I’ve run the short racing cyclone mkII on two bikes with 28 rear cogs. One early 80s road bike with horizontal suntour dropouts and one on a Bridgestone XO3 with suntour vertical do. The shifting on the suntour horizontal DOs was marginal. On the vertical DOs it was fine. Can’t hurt to try, if you are using horizontal DOs you might try different forward or backwards positions to see if the shifting improves
