I have a 1.5 head tube and putting a Sherman Slider on it. I for the life of me cant find the thread that had the adapters listed. There was one for about 50 bucks that was really nice, so any help there would be really cool. And here comes the stupid realization part, I am going to need a new stem as well, since the current one has a 1.5 stem .Am I correct in this assumption? The reason I ask is that Im going to wrench the bike myself, so Im going to try to minimize f*ck up time.
