I have a 2009 Raceface Turbine 3X9 crank set and I was wondering if it just simply switching out chainrings would be the solution to my conversion. I just want to know if the spacing is going to be out of wack basically. I know that I want 40,28 chainrings and obviously Raceface sells them, but I didn't want to buy them with out being certain they are going to work. Not replacing the crankset would be ideal of course but I suppose I could spring for a newer version if need be. All of the research I have done has pointed me towards raceface mainly producing a 4 bolt design cranks and chainrings. So I just want to know if they will work out correctly.
Thanks for the help everyone.
