What length of aerobar should I select?





Do you want the bar end thumb shifters right in your hands? The bar end thumb shifters add 1.5" (approx 38mm) to the overall extension length. Having your hands always around the shifters makes it easy to maintain a steady tempo/effort. If you don't move around a lot, and the distance you are riding is short, then select the shorter size. If you shift your position a lot, ride long distances, or plan on mounting a drinking system, then longer is better.
