A instrument used to find out the front-end geometry of a bike, particularly the angle of the steering axis (rake) and the space between the entrance axle and the contact patch of the entrance tire (path). This geometry considerably influences the bike’s dealing with traits, significantly stability and maneuverability. For instance, altering these measurements can have an effect on how the bike responds to steering enter, leans in turns, and maintains stability at totally different speeds.
Understanding and manipulating these dimensions are important for bike designers and builders to attain desired dealing with qualities. This instrument permits customers to experiment with totally different configurations and predict the ensuing dealing with earlier than bodily modifications are made. Traditionally, figuring out these values concerned advanced trigonometric calculations, however such instruments simplify the method, offering quick outcomes and facilitating iterative design. These insights are significantly helpful in customizing bikes for particular driving types or racing functions, enhancing security and efficiency.
