RipTide is driven to design, develop and make the best products ever made. When searching for the right bushing you want to look at three things; Riding style, Shape, and Durometer. The durometer of a bushing dictates how hard or soft a bushing is. The duro will determine how much lean you will get in your setup.
When deciding on the duro of a bushing you want to keep two things in mind. Your riding style and weight. If you are looking to do solely downhill then you would want a harder duro to provide you more stability where as a softer bushing would fit freeride applications better. Your weight will also help in deciding on a duro, the lighter you are, the softer the bushing and vice versa.
