It goes without saying that the Pro Circuit throttle tube is a top notch replacement piece, leaps and bounds better than the stock plastic tubes. The finish is perfect, and the tube is as light as plastic. One note: make sure you leave a tiny bit of space between the end of the tube and the bar end, otherwise (especially if your bars have the small rubber end pieces) the tube and bar will rub together, causing the tube to stick and not turn freely. I struggled with this for a while before realizing that pushing the tube all the way inward on the bar was stopping it from moving freely. Otherwise, very happy with my purchase.
