People just let the thread die. I'm letting it die even though, I'm pretty steamed. Thanks to everyone who provided useful information. My final decision (which I don't understand why people care so much) is uncertain but if I do it, it won't be with a 15t back cog. I knew that before I ever started the thread. We'll leave it at that. And yes one day I plan on getting into track racing if only the velodrome was closer. If you want to keep insulting me miss mom give me a PM. <- I guess this is me, yay. This is even harsher than my learning to skid thread. Which was pretty lame, but sometimes you got to ask questions to learn anything. (I actually think this troll icon is pretty cute, so I'm glad to be a troll)
