Yup, another demo 9 thread, lets try to keep it civil. I am interested in knowing the science between upsweep backsweep and so on. Most bars are different, although not by much, i cannot find out how it "works". I find that i run almost all of my bars tilted very far back, thats where it feels comfortable, but is there a downside to that. (health wise, or riding wise) It seems that alot of people buy bars on width, but not so much on sweep, which may be equally important? Asked all the people i knew, couldnt get an answer, so any help would be appreciated.
